NORTH AMERICAN COLEOPTERA. 177 
Revision of the genera an<l species or ANTHONO^IIWI 
inhabiting Nortii America. 
BY WILLIAM G. DIETZ, M. D. 
Since the publication of " The Rhynchophora," (Proc. Amer. 
Philos. Soc. 1876) but few new species belonging to the tribe under 
consideration have been described, while the amount of material ac- 
cumulated in our collections has been considerable. It was my in- 
tention, originally, to confine the following essay to Anthonomus 
proper ; the discovery, however, of new and important characters, 
as well as a greater appreciation of others heretofore deemed of but 
secondary importance in the classification of genera of this tribe, 
has led me, step by step, to include all the genera and species oc- 
curring within our faunal limits. The Anthonomini of Europe 
have been made the subject of a monograph by Desbrochers des 
Loges (Monographie des Balaninidse et Anthonomidse d'Europe et 
de confines Mediterranees, 1867), which has, however, scarcely offered 
a suggestion that might have aided me in the study of our North 
American species. The genus Orchestes was similarly treated by 
Brisout (Monogr. Ann. Fr. 1865). Very recently a paper has been 
published on the species of Anthonomus inhabiting Great Britain ; 
the latter publication I have not seen. 
In taking a general comparative survey of the present tribe of 
CurculionidjB, as presented by our own with that of the European 
fauna, one is struck with the few points of close similarity encoun- 
tered. Referring to Anthonomus proper, the European species, as 
far as I am able to judge by the not inconsiderable number repre- 
sented in my collection, present far greater uniformity, structurally 
as well as in general habitus, than our own. In all of them the 
funicle of the antennse consists of seven joints, and species entirely 
clothed with scales do not occur. The European genus Bradybatus 
Germ., in which the claws are connate at base, is not represented in 
our fauna. 
In defining the limits of the tribe, a modification of LeConte's 
arrangement becomes necessary. Several new genera have been 
included, whose position is somewhat doubtful, and which, with equal 
propriety, might have been placed in some other tribes of the Me-

corrhyiK'liid series. One of these, Alyeodes, Avhose affinity to the 
Erirrhini is well shown by the formation of the ventral segments, 
the covered pygidium and the simple claws, and by its toothed 
femora, would have to be placed after Dorytomus, but the obliquely 
truncated anterior thoracic opening, the prosternum short in front 
of the coxte, the antennal formation, etc., have induced me to place 
it in the present tribe. Another aberrant genus, Euclyptus, resem- 
bles Notolomus bnsalis Lee. in its general appearance, and also in the 
ventral formation ; the prosternum, however, is short in front of the 
coxse, the pygidium freely exposed, and the appendiculate claws 
warrant its position here. Elleschus, placed by Lacordaire among 
the Tychiides, I have retained in the present tribe ; the second, third 
and fourth ventral sutures are slightly bent backward at the sides; 
this character is also noticed in a few Anthonomi (A. elegans, juni- 
permus). Sin)ple claws occur in a small number of species, dis- 
tributed among several genera. This abnormality in the present 
tribe is the final result of a gradual reduction in development, passing 
from the bifid claws of some Anthonomi (Anthonomorphus) to the 
very small, though distinct tooth of Chelonychus and a few others, 
to disappears altogether in Epimechus, Ephelops, etc. A i-emarkable 
character exists in the subcontiguous middle coxre of Magdalinops. 
As will be seen further on, considerable importance has been attached 
to the relative length of the ventral segments. 
The sexes can generally be separated without much difficulty by 
keeping in view the following points : 
3Iale. — Beak stouter, more coarsely sculptured and generally more 
opaque ; autennie inserted nearer the apex, or more correctly speak- 
ing, the beak as already pointed out by Jekel (Annales de la Soc. 
Entom. de France, 1864) is less prolonged beyond the insertion of 
the antennae, the distance of the latter from the base is about equal 
in both sexes. 
Female. — Beak more slender, less coarsely punctured and more 
shining ; antenna; more remotely inserted from the apex. 
The third and fourth ventral segments appear to be a trifle shorter 
in the males ; the fifth is generally longer and rounded in the female ; 
shorter, subtruncate, or emarginate in the male, permitting the py- 
gidium to become more or less visible from below. The latter is 
more freely exposed in the male, rarely entirely covered by the apex 
of the elytra, while frequently only partially exjiosed or entirely 
concealed in the female. 
NORTH AMERICAN COLEOPTERA. ] 79 
The tibial armature, and especially the iiiucro of the posterior 
tibiie, is more slender and longer in the male than in the female. 
As is well known, all the members of the present tribe are phyto- 
phagous, and the greater number, no doubt, spermophagous. A few, 
like A. sijcophanta, P. crakegi, Coccotorus, etc., are said to breed in 
galls. I regret that I have nothing new to offer in the life-history 
of these insects. 
Family CURCULIONID^. 
Tribe Anthonomini. 
Mandibles bi-emarginate and three-toothed at tip; gular peduncle 
long ; oral organs small. 
Beak cylindrical, long and slender ; more rarely moderately stout 
and shorter (Macrorhoptus, some Anthonomi). More or less curved 
in all, but nearly straight in Macrorhoptus and Cionistes. Scrobes 
commencing at a distance from the buccal opening (less remote in 
the subgenus Paranthonorous) ; straight or somewhat curved ; directed 
against the middle or lower segment of the eyes; more rarelv (Mac- 
rorhoptus, Cionistes, Pseudanthonomus and Ephelops) oblique and 
directed beneath the eyes. 
Antennae variable, long and slender in the great majority ; in- 
serted at a distance from the apex (less remote in Paranthonomus) ; 
subbasal in certain Orchestes (Alyctus Thorns.). Scape long and 
slender, rarely (Macrorhoptus, certain Orchestesj short and stout ; in- 
crassate at its distal extremity and generally impinging against the eye, 
except in Tachypterus and those genera having the scrobes oblique 
and directed beneath the eyes. Funicle five to seven jointed, o-lab- 
rous; first joint stout, generally elongate; following joints variable, 
each with a verticel of six to ten stiff or flexible hairs; rarely 
(Acalyptus and Euclyptus) entirely pubescent. Clava elongate oval 
or elliptic, acuminate, pubescent; closely or more loosely articulate 
(first joint strongly glabrous in Magdalinops, some Anthonomi and 
Neomastix), rarely very elongate and very loosely articulate (Ta- 
chypterus and in the subgenus Leptarthrus), or broadly oval and 
closely articulate (Neomastix). 
Eyes at least moderately large, rounded and remote from the pro- 
thorax ; rarely (subgenus Anthonomorphus) small and subrostral in 
their position ; widely separated above, and nearly flat or modei-ately 
convex in most; rarely (.4. elegatis, leucosticfus ; Leptarthru.?, Or- 
180 WILLIAM G. DIETZ. 
chestes) very prominent, and approximate upon the front ; large, 
transversely oval and approximate beneath in Macrorhoptus. In a 
number of species the posterior margin of the eyes is more or less 
free and elevated, in consequence of wliich its surface is directed 
more anteriorly. 
Head more or less rounded or conical, not deeply immersed into 
the prothorax (except Cionistes). 
Prothorax wider than long (except A. hrunnipennis) ; narrowed 
in front; anterior opening obliquely truncate (except Acalyptus). 
Very rarely (Macrorhoptus, subgenus Anthonomorphus and Tricho- 
baropsis) emarginate antero-inferiorly and giving a feeble appearance 
of postocular lobes ; base bi-emarginate, produced in front of the 
scutel ; latter small, oval or rounded, densely pubescent or scaly. 
Elytra variable, generally wider at the base than the prothorax ; 
striato-punctate (striae confluent at base in most Pseudanthonomi). 
The outer margin shows the following variation : in those species 
having the elytra ample, that is, completely concealing the pygidium, 
the outer margin of one elytron forms a continuous horizontal line 
in its juxtaposition with the other and the outer stria unites with the 
sutural stria at an almost right angle. On the other hand, in those 
species in which the pygidium is freely exposed, the outer margin 
of each elytron ascends towards the apex, forming an angle in which 
the pygidium becomes more or less visible, and the outer and sutural 
strife unite at a more or less obtuse angle. In the text, the term 
dehiscent has frequently been used to denote the latter character, 
which varies greatly in extent, being most strongly marked in A. 
profundus, elegans, etc., and scarcely noticeable in A. nebulosus, j^e- 
ninsularis, etc. 
Prosternum short in front of coxpb (long in Acalyptus, a:nd mod- 
erately so in Antli. rufipes and disjunctus). Anterior coxse contigu- 
ous, rather large and prominent ; middle coxae separated by the 
mesosternum (subcontiguous in Magdalinops) ; the latter generally 
narrow, very rarely (subgenus Anthonomocyllus) wider than long, 
between the coxse. Metasternum moderately long (short in Antho- 
nomocyllus) ; side pieces narrowed posteriorly. Posterior coxae 
widely separated (only moderately so in Magdalinops). 
Ventral segments variable in length ; subequal in Macrorhoptus, 
Tachypterus, Magdalinops, and some Anthonomi. First and second 
segments elongate (scarcely elongate, with the first segment short 
behind the coxre in Anthonomocyllus ; very strongly elongate in 
NORTH AMERICAN COLEOPTERA. 181 
Anthoiioinopsis). Third and fourth segments shorter than the for- 
mer, rarely (Alycodes, Elleschus and Euclyptus) very short. The 
fifth segment, aside from sexual differences as noted before, attains 
its greatest length in Alycodes, Elleschus, Euclyptus and a few 
species of Anthononuis. 
The sutures are straight and deep, except the first, which is less 
deeply impressed (almost obsolete in Anthonoinopsis) ; the latter is 
curved in Elleschus, Anthonomopsis and Euclyptus. 
The pygidium varies in size ; it is oblique and concealed in both 
sexes in Alycodes, Macrorhoptus, Magdalinops, Tachypterus and 
Ellesciius ; more or less exposed, at least in the male in all the others. 
The more perpendicular its position, the more freely exposed it be- 
comes. It is inflexed in some males, where it fits into the emargina- 
tion of the last ventral segment ; this is most notably the case in 
Coccotorus, to a less extent in Anthonomocyllus and Neomastix. It 
is narrowly excavated in a longitudinal direction in the subgenus 
Paranthonomus. 
Legs never very stout (except Nanops) ; thighs more or less cla- 
\ate and generally toothed. Tibise generally slender; posterior of 
male curved in Anthonomocyllus and Cnemocyllus ; toothed inter- 
nally in ^. elegans and Leptarthnis irroratus. The apical armature 
requires more than a passing notice. It consists either of a hook, 
unguiculum, arising from the apical articulating surface, curved in- 
ward at almost a right angle with the tibial axis, or else a mucro, a 
prolongation of the internal apical angle into a point, in the direc- 
tion of or approximating to the longitudinal axis of the tibia. Being 
morphologically distinct, I have found difl^ereuces in the armature 
of sufiicient importance to be made use of in the separation of 
genera. The anterior and middle tibise are unguiculate, and the 
posterior mucronate in the majority of genera. All are unguiculate 
in Alycodes, Tachypterus, Magdalinops, Macrorhoptus, Chelonychus, 
Anthonomopsis, Elleschus and Nanops. Acalyptus has the anterior 
and middle tibise unarmed, the posterior feebly mucronate, while in 
Euclyptus all the tibise are unarmed, and in Xanthus the armature 
becomes very feebly developed. 
Tarsi variable, never very stout (except some species of Elleschus) ; 
frequently long and slender ; third joint bilobed, spongy or pubescent 
beneath, fourth joint generally of moderate length (short in Elles- 
chus, very long in several species of Cnemocyllus). Claws somewhat 
approximate and armed with a large tooth in the great majority ; 
182 WILLIAM G. DIETZ, M. D. 
the tooth is either curved inward at the apex and ap{)roximate to, or 
else straight and parallel with the tooth of the other claw. The 
tooth is small and inconspicuous in a few Anthonomi and Nanops, 
and especially so in Chelonychus, where the claws are also bent back- 
ward. The claws are appendiculate, that is, armed with a broad tooth 
beneath in Elleschus, Euclyptus and Orchestes, and entirely simple 
and more widely divergent in Alycodes, Epimechus, Ephelops, Xan- 
thus and Acalyptus. 
The species of the present tribe are mostly small insects, a few 
almost minute; none in our fauna, at least, exceeding 6 mm., or .25 
inch, in measurement.* The vestiture consists of pubescence or 
scales. In Anthonomochseta the pubescence is intermixed with erect 
set*. 
In conclusion of these introductory remarks, I desire to express 
my thanks to all who have kindly permitted the use of their material, 
especially Dr. G. H. Horn, Mr. E. A. Schwarz, Mr. H. Ulke, Mr. 
A. Baiter, Mr. R. Rauterberg and Dr. John Hamilton. I am under 
great obligation to my friend, Dr. Horn, who kindly made compari- 
sons for me with type specimens in the LeConte collection at Cam- 
bridge, and who again has undertaken the task to see this paper 
through the press.

subequal, third and fourth but little shorter than the second ; fifth a 
little shorter than the preceding segment in the % and of about 
equal length in the $. Pygidium concealed by the elytra and 
scarcely visible from below. Legs long and slender ; thighs feebly

beneath. Head convex, punctured and coarsely pubescent ; front 
foveate. Prothorax wider than long, narrowed in front ; sides nearly 
.straight behind, rounded in front ; antero-inferior margin eniarginate, 
giving rise to the appearance of feeble postocular lobes. Hind an- 
gles rectangular, slightly exserted. Base scarcely eniarginate each 
.side. Elytra oblong, very little wider at the base than the prothorax ; 
sides nearly parallel, broadly and conjointly rounded at the apex, 
which covers the pygidium completely. Striss almost obsolete; sur- 
face densely punctured, each puncture bearing a scale. Ventral 
segments subequal, third and fourth a little shorter than the others. 
Legs moderately long; thighs feebly clavate, anterior armed with a

TACHYPTERUS gen. nov. 
Head moderately convex. Eyes rather small, round and moder- 
ately convex. Beak long and slender; scrobes deep, linear, directed 
toward, but not quite attaining the eyes ; antenniTe inserted at a dis- 
tance from the apex, slender ; scape not attaining the eye ; funicle 
7-jointed, first joint long, 2-7 .short. Clava elongate, acuminate at 
apex, I'ather loosely articulate. Prothorax wider than long, con- 
stricted at apex, sides rounded ; base bisinuate. Elytra wider than 
the prothorax at base; each elytron protuberant at the base, fitting 
into the emargination at the base of the prothorax ; strongly convex 
and declivous posteriorly, concealing the pygidium. Surface tuber- 
culate or uneven, striiB punctured. Prosternum moderate in front 
of the coxae. Mesosternum rather narrow between the coxae. Meta- 
sternum short, about as long as the first ventral segment at middle. 
Abdomen broadly ovate, first and second segments moderately long, 
subequal, third and fourth shorter, fifth longer. Legs moderately 
stout. Thighs feebly clavate, anterior bidentate, middle and poste- 
rior unidentate. Tibise somewhat compressed, anterior subangulate 
about the middle, bisinuate ; articulating surface oblique, all un- 
guiculate at the a|)ex. Tarsi rather stout; first joint a little longer

pilose beneath. Claws cleft, teeth convergent. 
The ty|)e of this genus is Aiith. quadrigibbus Say, a common spe- 
cies found over our whole territory, and to which I have to add a 
new s[)ecies. They are readily distinguished as follows : 
Elytra strongly tnberculate, alternate interspaces more prominent, pubescence 
flense quadrigibbus Say. 
Elytra feebly tnberculate, interspaces equal, pubescence sparse... cousors n. sp. 
1. T. quadrigibbus Say. Plate v, figs. 3-3a. 
The generic descri|)tion with the above synoptic reference, will 
readily distinguish this well-known species from any other. A large 
tubercle is situated on the third interspace on the summit of the de- 
clivity, another on the fourth nearer the apex. There are also some 
irregular elevations on the fifth and seventh interspaces. The elytra 
are transversely impressed behind the scutellum, and this space is 
densely clothed with whitish pubescence. The prothorax has three 
narrow lines of whitish pubescence, while a lateral stripe of bright 
yellow pubescence is continued upon the densely pubescent side 
pieces of meso- and metathorax.

The species varies considerably in the development of the tuber- 
cles, as well as in size and general coloration. Conimon in the Spring 
on Cratcegas oxyacantha L. The sexes are readily distinguished by 
the usual characters. Long. 3-4.5 mm. ; .12-18 inch. 
Hab. — Occurs probably over our whole territory. Specimens are 
before me from the Eastern and Western States; Texas, California. 
•2. T. consors n. sp. — Ovate, rufotestaceous, thinly pubescent. Head con- 
vex, punctured with a fine frontal carina; frontal puncture deep. Eyes moder- 
ately convex, small. Beak long and slender, feebly curved, median elevated Hue 
not pronounced, substriate each side and densely punctured. Antennae slender, 
second joint scai'cely longer than the third. Prothorax broadly rounded on the 
sides and feebly constricted at apex, base not strongly bisinuate. Surface very 
coarsely punctured with a dorsal line of condensed, white pubescence. Elytra

species. 
CIONISTES gen. nov. 
A short, stout, convex species from California, denselv clothed 
with fine pubescence, forms the type of this genus. 
Beak moderately stout, cylindrical, slightly widened toward the 
apex and almost straight ; striato-punctate. Scrobes short, oblique, 
evanescent posteriorly. Antennae inserted about one-half ( S ) or 
two-fifths ( 9 ) from the apex ; scape slender, impinging against the 
lower segment of the eye; funicle rather stout, T-jointed, first joint 
long, n(jt very stout ; joints 2-4 a trifle longer than wide, 5-7 trans- 
verse ; club elongate-ovate, very closely articulate. Head deeply 
imiuersed into the prothorax; front rather flattened with a deep, 
round fovea. Eyes round, approximate above. Prothorax wider 
than long, strongly narrowed in front ; surface uneven ; base straight 
each side, produced in front of the scutelhim, the latter oblong. 
Elytra wider at base than the prothorax ; humeri prominent, rounded, 
a little widened to behind the middle and rapidly narrowed to and 
conjointly rounded at apex, which covers the pygidium completely ; 
surface irregular, tuberculate, very convex, striate; strise obsolete on 
the post-scutellar space and toward the margin of the elytra ; punc- 
tures obsolete, or at least concealed by the dense pubescence ; inter-

spaces densely punctulate. Prosternum very short in front of coxae. 
Mesosterniiin moderately wide, but short, between the coxse and al- 
most perpendicular in front. Metasternum short, as long as the first 
ventral segments at middle. Abdomen broadly ovate; first and 
second segments rather short, segments 3-5 about equal, and each but 
little shorter than either of the former segments ; pygidium not 
visible, under surface sparsely pubescent. Legs rather short and 
stout. Femora clavate, all toothed. Tibije short, slightly compressed, 
subparallel, feebly bisinuate internally ; articular surface scarcely 
oblique. Anterior and middle tibiae feebly unguiculate, posterior 
nnicronate at apex. Tarsi stout, first joint but little longer than the 
second, and each with several suberect, stout, clavate bristles, arising 
from the upper surface ; third joint deeply bilobed. Claws armed 
with a large, obtuse tooth. 
Related to the preceding genus by the form of the abdomen, the 
covered pygidium and the irregular, tuberculate surface, but readily 
distinguished from it by the mucronate posterior tibise and from all 
others by the short, oblique scrobes. 
A single species. 
1. C. insolens n. sp. Plate v. figs. 4-4a. — Riifo-piceous, densely clothed 
with fine yellowish pubescence. Protliorax with a prominent, serai-circular ele- 
vation, in front of which there is a broad, transverse impression ; broadly im- 
pressed each side of base. The elevated points are clothed with pale, the de- 
pressions with fulvous pubescence. Elytra broadly oval, a trapezoidal space in 
front and extending about one-third the length of the elytra, rufous and clothed 
with pale ochreous pubescence. The rest of the surface is dark piceous and 
clothed with yellowish gray pubescence; an oblong tuberosity on the third, fifth 
and seventh interspaces about their middle and arranged in a somewhat oblique 
line. A small but acute tubercle on the third interspace posteriorly. Posterior 
to the basal margin is a broad, transverse elevation and between this and the 
oblique row of tubercles each side, a broad impression : another tubercle is situ- 
ated on the fifth and seventh interspaces anteriorly. The under surface is more 
thinly pubescent. Long. 2.25 — 2.5 mm.; .09 — .10 inch.

AIVTHOIVOMUS Germ. 
As here restricted, the genus presents the following characters: 
Beak variable, generally long and slender, more rarely shorter and 
stouter. Scrobes long, directed against the eye. Antennje variable ; 
scape reaching the eye, or very nearly so ; funicle 6- or 7-jointed. 
Club ovoidal, annulate in some, more looselv articulate in others. 
NORTH AMERICAN COLEOPTERA. 189 
Elytra distinctly striate and punctured, leaving the pygidiuni, at 
least in the male, more or less exposed. Prosternum short, very 
rarely (A. rvfipes, disjundus) somewhat elongate in front of the 
coxse. Mesosternuni at least moderately wide between the coxse. 
Ventral segments variable; pygidium visible. Thighs generally 
toothed, more rarely nmtic. Tibial armature distinct, anterior and 
middle tibia? unguiculate, posterior mucronate at apex. Claws gen- 
erally armed with a large, distinct, more rarely with a small, incon- 
spicuous tooth. 
This genus contains by far the largest number of species, whicli 
vary greatlv, not merely in their general habitus, but also in more 
important characters, possessing at least a subgeneric value. I have 
deemed it, therefore, expedient to establish a number of subgenera, 
in preference to still further increasing the number of those having 
full generic value. As will be seen, I have included Coccotorus Lee. 
in the present genus, as the unusually deep emargination of the fifth 
ventral segment of the % , has after all but a relative value, and 
should therefore not remain distinct.

The above description has been taken from a single % specimen 
in the collection of Mr. E. A. Schwarz, who obtained it from Mr. 
Bruner. This appears to be a distinct species, but having only a 
unique specimen for comparison, larger series may prove the above 
characters to be inconstant, and therefore consider the matter still 
sub-judice. 
Subgenus Anthonomocyllus. 
This subgenus has for its type A. elegans Lee. The beak is long 
and slender, feebly curved, striate and earinate. Antennae inserted 
two-fifths ( S ) or one-half ( 9 ) from the apex ; scape slender, im- 
pinging against the eye ; funiele 7-jointed. Club not closely ar- 
ticulate, somewhat shining and sparsely pubescent. Eyes convex, 
posterior margin elevated, free. Head globose, punctured and pu- 
bescent. Prothorax convex, wider than long, and about twice as 
long above than below ; strongly narrowed in front; base bisinuate. 
Elytra wider at base than the prothorax, broadly oval and very 
convex ; striato-|)unctate. Presternum very short in front of the 
coxpe. Mesosternum rather wide between the coxse, declivous in 
front. ^letasternum short. Middle coxse rather widely separated. 
First ventral segment short behind the coxse. Male: segments 1-4 
short, nearly equal, fifth elongate, about twice as long as the pre- 
ceding and emarginate. Female : segments subequal, fifth not elon- 
gate. Pygidium exposed, convex ; inflexed and more freely exposed 
in the male, perpendicular and less exposed in the female. Legs 
rather stout ; femora strongly clavate, all armed with a large, acute 
tooth. Tibiae stout, toothed or not internally ; posterior tibiae curved 
in the male, straight in the female. Tarsi rather slender, third joint 
broadly bilobed, last joint long. Claws armed with a long, slender 
tooth. 
To this genus I refer also A. pusillus Lee. and two new species, 
which, while presenting the es.sential characters, differ by the first

two ventral segments being a little longer and the anterior tibiae not 
toothed internally. In foot, they may be looked upon as forming 
the end of a series, of which A. elegans forms the type, and where 
intermediate forms are wanting, or at least not represented thus far 
within our ftiunal limits. All are robust, broadly oval and very 
convex. The vestiture consists of scales intermixed with a fine, 
semi-procumbent pubescence. 
They are distinguished as follows : 
Eyes protuberant, narrowly separated above. Plate v, fig. 7a. 
Anterior and middle tibiffi toothed internally, densely clothed with variegated 
scales elegaiiN.

the prothorax and somewhat protuberant each side of the scutel; sides rounded, 
almost imperceptibly wider behind the middle, strongly declivous behind. Striae 
fine: punctures concealed by the scales. The pattern formed by the scales is 
complex; the ground color is a silvery gray to grayish brown. Scutel and a 
spot each side of the suture behind it white; base, sides, two approximate, ob- 
lique lines before the middle enclosing a silvery white line and continued along 
the sutural interspace to a posterior transverse fascia, brown. The space between 
the latter and the anterior oblique band is yellowish brown, A humeral spot 
and another each side of scutellum seal-brown. Each ventral segment with a 
row of long, blackish hairs. Thigh armed with a large triangular tooth. Tibise

Agree? with A. elegans in form, convexity, and the closely approxi- 
mated eyes, but differs markedly by the upper surface being simply 
pubescent, with spots and lines of large, condensed scales. 
A unique S in my collection. The first ventral segment is a little 
longer behind the coxtie, and the pygidium less inflexed than in 
elegans.

It gives me pleasure to dedicate this species to my friend and col- 
league, Dr. J. Hamilton, whose zeal in behalf of entomology is well 
known. 
Three specimens; coll. of Dr. Hamilton. The second ventral 
segment is a little longer than the third or fourth, and the fifth a 
little shorter than the two preceding segments united. It is closely 
related to the following species : 
4. A. pusilliis Lee. — Not very unlike the former, from which it differs in 
the following characters: much smaller, more broadly oval ; ferruginous to pi- 
ceous. The scales are smaller, and the pubescence more conspicuous. Front less 
squamous; fovea obsolete. Antennse a trifle stouter; second joint of funicle 
stout and but a trifle longer than the third ; outer joints more distinctly wider. 
Elytra more distinctly wider at base than the prothorax and scarcely longer than 
wide. Markings obscure, almost obsolete. The tooth on the hind femur is 
scarcely noticeable. Tibife feebly bisinuate internally. The third and fourth 
ventral segments are very short in the male; the second longer than the first 
behind the coxae, and the fifth as long as the two preceding segments together. 
In the female the second and fifth segments are about equal, the others shorter.

Hab. — Massachusetts. 
Subgenus Anthonomorphus. 
Distinguished from the other subgenera by the eyes, which are 
small, rubrostral in their position and somewhat approximate upon 
the front. The beak, which is slender, has four grooves or deep 
strijfi, extending from the base to about the insertion of the antennae. 
Scape of antennae slender ; funicle rather stout, more so in the female ; 
first and second joints elongate, joints 3-7 short, about as long as 
wide (■£ ), or somewhat transverse ( 9 ). The head is conical ; front 
foveate. Prothorax wider than long, strongly narrowed in front ; 
base bisinuate, emarginate at its antero-inferior margin, giving the 
appearance of feeble postocular lobes ; surface coarsely punctured. 
The elytra are elongate-oval, but little wider at the base than the 
prothorax. Mesosternum narrow between the coxse. Ventral seg- 
ments subequal, third and fourth but little shorter than the others. 
NORTH AMERICAN COLEOPTERA. 195 
Legs slender ; femora clavate, at least the anterior bidentate. Tibiae 
feebly bisinuate internally; apical armature strongly developed. 
Tarsi slender, first joint elongate, third feebly bilobed, spongio-pilose 
beneath, fourth joint moderately long. Claws large, broad, slightly 
divergent and deeply bifid, especially the anterior; teeth scarcely 
approximate to each other. The vestiture consists of coarse pubes- 
cence. 
The type of this subgenus is A. falvus Lee, to which I have to 
add two new species from Lower California, very recently received by 
Mr. H. Ulke. The species are at once recognized by the eyes being 
situated at the base of the rostrum ; they are smaller and narrower 
in A.fulvus than in the other species. They are readily distinguished 
as follows : 
Pubescence forming patterns on the elytra ; anterior femora alone bidentate. 
ftllTUS. 
Uniformly pubescent ; all the femora bidentate. 
Black ; liead constricted behind the eyes, which appear more prominent. 
peninsularis. 
Ferruginous; head not constricted behind the eyes; front transversely im- 
pressed pervilis. 
A. fulviis Lee Plate v, figs. 8, 8«. — Elliptic, ferruginous, thinly clothed 
above with coarse, pale yellowish pubescence. Beak not very slender, quadri- 
sulcate, sulci punctured. Antennse inserted one-third ( '^ ) or two-fifths (9) 
from the apex. Eyes transversely oval, slightly convex. Head finely and re- 
motely punctured, moderately constricted behind the eyes; frontal fovea large 
and deep. Prothorax about one-half wider than long; sides rounded; apex 
feebly constricted ; surface very coarsely and subconfluently punctured, each 
puncture bearing a yellowish hair; pubescence condensed along the median line. 
Elytra a trifle wider at the base than the prothorax, sides very feebly rounded, 
gradually narrowed to and slightly separated at the apex; strije fine, feel)ly im- 
pressed ; punctures moderate, elongate, coarser and more deejily impressed at the 
base; interspaces flattened, remotely punctulate, pubescence condensed in lines 
as follows : short post-scutellar line, second and eighth interspace from near the 
base to the apex, apical half of tenth, an anterior oblique and posterior subtrans- 
verse line behind the middle and extending from the eighth interspace to the 
third, where they coalesce; between these latter lines another exists on the sixth 
interspace. Scutellum densely pubescent. Underside punctured, more densely 
pubescent, especially on the thoracic side pieces. Long. 4.5 — 5 mm. ; .18 — .20 inch. 
Hab. — Kansas, Indian Territory, Texas. 
A readily recognized species. 
A. peiiiiisiilaris n. sp. — Oblong oval, pitchy black, conspicuously clothed 
with long, coarse, dirty white pubescence, which is scarcely more dense beneath 
than above. Beak slender, carved, strife well impressed, coarsely punctured, 
apical portion more remotely punctured ( % ). Auteuuie slender, inserted two- 
196 WILLIAM G. DIETZ, M. D. 
fifths ( % ) from the apex; second joint of fiinicle longer than the third. Eyes 
almost round, moderately convex. Head distinctly constricted behind the eyes, 
giving the latter the appearance of prominence ; rather coarsely, but not densely 
punctured, sparsely pubescent; frontal fovea elongate, superficial. Prothorax 
less thau one-half wider than long and nearly twice as wide at the base than at 
the apex, latter scarcely constricted; sides regularly rounded; surface coarsely 
and rather densely punctured, evenly pubescent. Elytra oblong oval, distinctly 
wider at the base thau the prothorax ; sides feebly, apex more strongly and con- 
jointly rounded. Striae wide, deeply impressed, especially nearer the base , punc- 
tures moderately large and approximate, especially nearer the base; interspaces 
feebly convex, punctulate and sonewhat rugose: surface evenly pubescent, scu- 
tellum more densely so ; underside of thorax finely and more remotely, abdomen 
densely and more coarsely punctured; pygidium slightly exposed {%). Legs 
slender ; femora feebly clavate, bidentate, outer cusp of middle and posterior 
feeble. Tarsi slender, claws bifid, tooth long and slender. Long. 5.5 mm. t .22 
inch. 
Hab. — Lower California; exact locality not given. 
A % specimen in Mr. H. Ulke's collection, very recently received. 
Structurally, this species agrees very closely with the foregoing, but 
the eyes are nearly round, the elytra almost conjointly rounded at 
the tip and all the femora are bidentate. In coloration and vestiture, 
it is totally diffei-ent. 
A. pervilis n. sp. — Agrees with the preceding in all particulars, except the 
following : ferruginous, underside of thorax piceous. Head not constricted 
behind the eyes, which are scarcely convex; a transverse, deeply indented line 
above the eyes. The pygidium is very little exposed. Long. 5 mm. ; .20 inch. 
Hab. — Lower California. 
A 9 specimen, received with the foregoing from INIr. H. Ulke for 
determination. It is with some reluctance that I record this species 
as distinct from peninsnlaris, but the strikingly different coloration, 
which is not due to immaturity, the head not constricted behind the 
eyes and the deep, transverse indentation above the eyes, seems to 
warrant its separation, until more extensive series of specimens shall 
establish its identity with the former. 
Subgenus Trichobarapsis. * 
A coarsely pubescent species from Texas, having the prosternum 
emarginate and the seventh joint of the funicle continuous to the 
club, forms the type of this subgenus. The anterior and middle 
femora are bidentate, posterior with a single tooth. The tibiae are 
bi-eraarginate internally, and the armature well marked. The tarsi 
are slender; claws broad and widely separate, armed with a tooth 
nearly as long as the claw.

'a. texaiiiis n. sp. Plate v, fig. 9.— Elongate oval, rufo-piceoiis, densely 
clothed nbove and beneath with very coarse, yellowish gray pubescence. Beak 
moderately slender, somewhat depressed and shining; punctured and pubescent 
at the base; 4-sulcate from the base to the insertion of the antennfe. sulci punc- 
tured; beyond, finely and remotely punctured. Autennse not very slender; 
secoud joint of funicle much longer than the third ; joints 3-7 subturbinate, 
somewhat transverse and becoming gradually wider ; seventh joint continuous 
to the club. Verticels consisting of about 8-10 stiff, long white bri.stles. Club 
elongate ovate, joints rather closely connate, pubescent. Head convex ; occiput 
finely, front somewhat flattened and more coarsely punctured ; transversely im- 
pressed behind the eyes, frontal fovea deep, elongate. Eyes moderately convex, 
not free behind. Prothorax conical, one-third wider than long and about twice 
as wide at the base than at the apex ; sides feebly rounded from base to apex, 
latter not constricted, slightly emarginate; base feebly bisinuate. Surface feebly 
convex, densely and coarsely punctured and pubescent; pubescence condensed 
along the median line ; anterior thoracic opening not oblique, rather deeply emar- 
ginate at its inferior margin, giving rise to the appearance of postocular lobes, 
which are ciliate with long, flying hairs. Elytra oblong, scarcely wider at the 
base than the prothorax ; sides nearly straight, parallel for two- thirds their length, 
gradually rounded to and feebly separated at the tip, leaving the pygidium ex- 
posed ; base straight; strife and punctures deep and rather coarse on the disc, 
less so toward the apex; interspaces convex, especially toward the base, finely 
punctured; pygidium perpendicular. Legs slender; femora feebly clavate, an- 
terior and middle bidentate ; hind thighs unidentate; all the tibiae bisinuate 
internally and subangulate above the middle. Tarsi slender. Long. 3.25—3.75 
mm. ; .13 — .15 inch. 
Hab. — Texas. 
In form this species resembles somewhat Trichobaris, without, 
how^ever, the denuded spots; through the emarginate prosternum and 
the outer joints of funicle continuous to the club, the present subgenus 
approaches Macrorhoptus, and through the former also Anthonomor- 
phus. 
Subgenus Leptarthrus. 
Under this subgeneric name I have separated from Anthonomus 
proper two new and peculiar species from Florida, in which tlie an- 
tennal club becomes greatly elongated and the joints very loosely 
articulate ; the beak is slender. Antennte very slender, funicle 7- 
jointed, with the first and second joint longer than the following 
ones. Pr(«ternum very short in front of coxse ; mesosternum mod- 
erately wide between the coxte. Ventral segments subequal ; first 
and second moderately long, former longer than the latter; seg- 
ments 3 and 4 short, equal, or nearly so; fifth segment a little 
longer than the fourth in the male, and about equal to it in the 
female ; pygidium exposed in both sexes ; anterior legs h)nger and

The toothed tibije distinguish this species from the preceding, and 
in this respect agrees only with A. elegans^ from which it is sufficiently 
distinguished otherwise. 
A specimen in Mr. Schwarz's collection has the elytra more uni- 
formly whitish, with a few darker spots ; the alternate interspaces 
are a trifle more convex, and the tuberosities on the summit of the 
elytral declivity are obsolete. I do not consider it specifically dis- 
tinct. 
Subgenus Paranthonomus. 
This subgenus, which has for its type ^4. profwidus Lee, is readily 
recognized by the deep, longitudinal excavation of the pygidium. 
Beak cylindrical, rather slender and punctured ; scrobes connuen- 
cing one-Hfth ( S ) or one-third ( 9 ) fi'om the buccal 0|>ening, straight, 
deep and attaining the middle of the eyes ; the latter are round, con- 
vex. Head conical, punctured ; front foveate ; antennae slender, in- 
serted less than one-quarter ( S ) or one-third ( 9 ) from the apex ;

joint long, second n)uch shoTter and abont twice as long as the third 
joint ; joints 2-7 a little longer in the male than in the female ; club 
long, elliptical, acuminate at apex, and rather loosely articulate; 
shining and thinly pubescent. Prothorax wider than long, narrowed 
anteriorly and somewhat constricted at the apex, convex ; base feebly 
bisinuate. Elytra oblong, wider at the base than the prothorax ; 
humeri prominent, rounded ; a little wider and more strongly convex

freely exposed ; scutel oblong, densely pubescent. Presternum short 
in front of the coxse ; mesosternum rather narrow between the coxie. 
Ventral segments more unequal in the male ; third and fourth shorter, 
fifth nearly twice as long as either the third or fourth segment, with 
a smooth semi-circular space at the apex. Female: segments nearly

ones ; pygidium exposed, perpendicular, with a deep, sharply defined, 
longitudinal excavation. Legs long and slender ; femora clavate, 
toothed ; tibise slender, armature strong ; tarsi slender, first joint 
elongate, longer than the second ; third deeply bilobed, spongio- 
pilose beneath ; fourth joint long and slender ; claws large, separate

The vestiture consists of rather coarse, whitish pubescence, which, 
on the elytra, is intermixed with fine, blackish hairs. 
The genus is represented by three species in our fauna, while in 
Europe it is represented by A. pubescens, and ])robably A. pyren<jevs. 
Our species may be tabulated as follows: 
Thorax coarsely and less densely punctured; pubescence sparse, black hairs very 
scant ; tooth of anterior femur without accessory cusp. 
Larger, piceo- ferruginous ; prothorax nearly parallel at the sides behind, and 
less transverse; first two joints of funicle relatively longer.

Thorax more finely and densely punctured ; pubescence more cons])icuous, black 
hairs more evident; anterior femoral tooth with an accessory cusp.

Hab. — Illinois, Pennsylvania, Maryland, Michigan. 
The apex of the fifth ventral segment in the male projects in the 
form of a small lobe, which fits into an emargination of the py- 
gidium. 
A. viilpiiillS n. sp. — Agrees with the preceding species, but is smaller, and 
of a reddish color; the first and second joint of the funicle are relatively shorter, 
the latter scarcely one-half as long as the former in the % and still shorter in 
the 9 ; t'le following joints are about equal in both sexes. Prothorax less than 
one-half wider than long and more rounded at the sides; the elytral interspaces 
less convex and more finely rugulose; the underside is scarcely darker than the 
rest. Long. 2.75 mm. ; .11 inch. 
Hab. — Pennsylvania (Hazleton). 
Two males and three females were taken by myself some years 
ago by bush beating and considered as S. rubidvs Lee, from which 
it differs by its larger size, more reddish color, coarsely punctured 
and finer pubescence. 
.4. I'libulns Lee. — Oblong oval, scarcely wider behind, testaceous, rather 
densely clothed with yellowish pubescence. Beak punctured, with a smooth

dant than in the two preceding species. Scutellum densely clothed with pale 
yellowish pubescence; scutellar region dusky, suture dark, underside darker 
and rather densely clothed with long pubescence. Legs testaceous, thighs 
strongly toothed, the anterior pair with a well marked additional tooth ; anterior 
tibia? curved near the base and bisinuate internally. Long. 2.2 — 2.5 mm. ; .09 — 
.10 inch. 
ifofe.— District of Columbia, Maryland (Deer Park). 
Readily recognized by its pale color, small size, very convex eyes, 
and the additional cusp of the anterior thighs. The black hairs on 
the elytra, although more abundant than in the two preceding species, 
are scarcely visible, except under a lens of considerable power.

202 WILLIAM G. DIETZ, M. D. 
As already pointed out by LeConte (op. cit. p. 199), this cannot 
be A. hehohis Boh. (Sch. Gen. et Sp. Cure. vol. vii, 2, p. 224), as the 
description "femoribus anterioribus breviter unidentatis, posticis 
muticis," and again, " Thorax latitudine postica nonnihil brevior," 
does in no wise correspond with the species under consideration. 
Subgeuus Anthonomus. 
I have but little to add to the definition of the genus as here re- 
stricted, to what has been given in the table. The fifth ventral seg- 
ment of the male is but rarely emarginate. The funicle is 6-jointed 
in but a small number of species. 
The present subgenus contains by far the greatest number of spe- 
cies, which present structural difl^erences of considerable importance, 
and which I have made use of in subdividing the species into the 
following groups : 
Funicle seven-Jointed. 
Upper surface pubescent (scales, if any, are arranged in spots or lines, except A. 
concinnus) ; claws strongly toothed. 
Elytra conjointly rounded at the apex; pygidium of % very little exposed; 
pubescence dense, arranged in patterns on the elytra. 
nebulosus Group. 
Elytra not conjointly rounded at the apex ; pygidium, at least of the male, more 
fully exposed ; pubescence uniform, or condensed in spots or lines 
without distinct patterns. 
Anterior femora bidcntate g-ularis Group. 
Anterior femora uuidentate. 
Third ventral segment longer than the fourth; fifth segment shorter, 
rarely as long as the fourth in the male. 
Pubescence of elytra uniform, rarely condensed in spots or lines, and 
without denuded patch or fascia. PI. vi, fig. 14...suturalis Group. 
Elytra with spots or lines of condensed pubescence, enclosing a denuded 
patch or fascia. PI. vi, fig. 15 sig-natus Group. 
Third and fourth ventral segments equal or nearly so; fifth segment of 
male longer than the fourth. PI. vi, fig. 16....scutellatus Group. 
Upper and lower surface pubescent; claws armed with a small, inconspicuous 
tooth juniperinus Group. 
Upper and lower surface clothed with scales; tarsi long squamosus Group. 
Funicle six-jointed. 
Claws armed with a large, distinct tooth subfasclatus Group. 
Claws armed with a short basal tooth ung-ularis Group. 
nebulosus Group. 
I have nothing further to add to the description of this group, 
as given in the synopsis, except that the tooth of the claws is rather 
NORTH AMERICAN COLEOPTERA. 203 
shorter and more obtuse than in the other species with 7-jointed 
funicle, in this respect resembling rather A. pyri, ulmi, ornatns, etc., 
of Europe. In fact, the two species belonging here, one of wliich 
is introduced from Europe, are more characteristic of the fauna of 
that continent than our own. 
The two species are readily distinguished as follows: 
More robust, anterior thighs bideutate, pubescence more squamiform. 
iiebulosus Lee. 
More slender, anterior femur with a large triangular tooth, pubescence piliform. 
poinoruiu Linn. 
\. iieblilosiis Lee. — Oval, brownish piceous; pubescence dense, rather 
squamiform of a grayish, brown or fawn color and intermixed with very fine, 
short hairs, forming distinct patterns on the elytra. Beak long, slender, mod- 
erately curved, quadristriate, lateral striae deeper and longer, punctured and 
scarcely pubescent. Antennte inserted remotely from the apex, rather long and 
slender ; scape slender, paler than the rest; second joint of fuuicle slender and 
longer than the third ; joints 3-4 slightly elongate, longer than the following 
joints. Eyes convex, posterior margin free. Head convex, pubescent; occiput 
more finely, froTit more coarsely and densely punctured. Prothorax more than 
one half wider than long; sides more strongly rounded in front, strongly nar- 
rowed anteriorly; apex feebly constricted and impressed at the sides behind the 
anterior margin ; surface evenly, densely and rather coarsely punctured, rather 
sparsely pubescent with three narrow, paler lines. Elytra one-fourth wider at 
the base than the prothorax, oblong, sides feebly rounded and gradually nar- 
rowed to the tip, which is conjointly rounded ; striae impressed, punctures coarse 
and rather closely placed; interspaces convex, punctulate; scutellum white; the 
pubescence is arranged as follows: a trapezoidal basal space, a double curved 
band commencing below the humerus and extending obliquely to the middle of 
the suture, thence curving outward in a transverse direction to the outer margin : 
within the space included is another triangular area of pubescence; underside 
of body and head clothed with squamiform pubescence. Abdomen less densely 
and more coarsely pubescent, pygidium very little ( '^ ) or not exposed ( O ). 
Legs moderately stout, thighs clavate, anterior bidentate, internal tooth long, 
outer tooth small, triangular and connected with the former at the base. Tibiae 
rather shorter and stouter than usual ; anterior pair curved near the base, pos- 
terior near the apex ; armature strong. Tarsi slender, pubescent beneath ; claws 
armed with a rather short tooth, which is submedian on the anterior tarsi and 
becomes almost basal on the posterior. Long. 3.75—4.25 mm. ; .15— ,17 inch. 
Male. — Pygidium carinate, depressed at the sides, fifth ventral 
segment feebly lobed at the middle. 
Fe?na/e.— Pygidium convex, fifth ventral segment bilobed at the 
middle. 
Hab. — Ohio, Michigan, Illinois, Missouri. 
Varies in the ground color from pale ferruginous to almost black, 
and also in the patterns of pubescence. The external cusp on the 
204 WILLIAM G. DIETZ, M. D. 
anterior thigh varies in pnjminence, and in one specimen before 
me becomes almost obsolete, being replaced by several serratures on 
the outer margin of the internal, or large tooth. This modification, 
however, could not give rise to confusion with the next species in 
which the anterior femoral tooth is much larger, and the external 
margin perpendicular. In the majority of specimens examined the 
pygidium is entirely concealed by the elytra. 
A. poiiioruni Linue. Plate vi, fig. 12. — Less robust than the preceding, 
dark brown or piceous, pubescence fulvous brown, intermixed with pale. Beak 
slender, subopaque, feebly striate, a median elevated line, pubescent at the base, 
funicle stouter than in nebulosus ; second joint but little longer than the third, 
joints 3-7 transverse. Eyes convex, posterior margin not free. Head short, 
conical, rather coarsely punctured and pubescent, more coai-sely so and rather 
concave between the eyes; frontal puncture small, but deep. Prothorax about 
one-half wider than long, narrowed from the base, latter scarcely emarginate 
each side, median lobe almost obsolete; sides feebly rounded and scarcely con- 
stricted at the apex, a curved impression behind the anterior margin ; surface 
densely punctured, pubescence coarse, hair-like, almost concealing the sculpture, 
brown with a median and lateral vittse paler. Elytra oblong, one-fourth wider 
at the base than the prothorax ; humeri rounded, sides feebly so, conjointly 
rounded at the apex, declivity more oblique than in nebulosus, transversely 
impressed behind the base; strife rather wide, but superficial; punctures large 
and deep, and like the striae more or less concealed by the pubescence, latter 
dense and less coarse than in the preceding species ; a subdenuded spot near the 
base of the third interspace; an oblique fascia behind the middle, extending 
from the seventh to the first interspace; a triangular spot on the declivity, with 
its base on the first interspace ; scutellum, a few small spots on the disc and along 
the margin of the oblique fascia, white. Beneath, thorax rather coarsely, abdo- 
men more finely punctured and thinly pubescent, except the prothorax. Legs 
more slender, femora feebly clavate, unidentate, anterior femoral tooth very 
large, acutely triangular, external margin perpendicular; tibife and tarsias in 
nebulosus. Long. 4 mm. ; .16 inch. 
Hab.—Oh\o. 
A female specimen of this common European species was received 
some years ago among specimens of nebulosus, to which it bears a 
superficial resemblance. The less robust form and large, single tooth 
of the anterior thighs, will readily distinguish the present species. 
. It is with some hesitancy that I introduce this species as occurring 
in our fauna, based, as it is, on a unique specimen. 
gularis Group. 
The species belonging to this group have the anterior thighs bi- 
deutate, the pygidium rather freely exposed, and the j)ubescence 
coarse or sparse, without any attempt at forming distinct patterns.

The second joint of funicle is longer than the third. Legs and tarsi 
slender (except f/randis), claws armed with a long, slender tooth. 
The ventral segments not very unequal, the fifth generally longer 
than either the third or fourth. 
They may be tabulated as follows : 
Larger, pubescence coarse, anteunse iuserted more remotely from the apex.

A. graiidii^ Boh. — Stout, subovate, rufo-piceous and clothed with coarse, 
pale yellowish pubescence. Beak long, slender, shining, and sparsely pubescent 
at the base; striate from base to the middle, strife rather coarsely punctured ;

the sides: pubescence more dense along the median line and on the sides. Elytra 
oblong, scarcely wider at the base than the prothorax ; sides subparallel for two- 
thirds their length, thence gradually narrowed to and separately rounded at the 
apex, leaving the pygidium moderately exposed ; striae deep, punctures large and 
approximate; interstices convex, rugulose, pubescence somewhat condensed in 
spots. Legs rather stout, femora clavate, anterior strongly bidentate, inner tooth 
long and strong, outer one acutely triangular and connected with the former at 
the base ; middle and posterior thighs unideutate. Tibiae moderately stout, an-

blackish, and rather widely separate ; tooth almost as long as the claw. Long. 
5—5.5 ram. ; .20— .22 inch. 
Hub. — Mexico, Texas. 
Whether the introduction of this species into our faunal limits is 
permanent or not, future observations must decide. Three specimens 
are before me, two in the collection of Dr. Horn,* labeled Mexico, 
and a s|)ecimen in Mr. Schwarz's collection from Texas. Thev tallv 
well with the description given by Bohemann, though the descriptive 
expression in reference to the elytra — " thorace plus triplo longiore"

— is not correct. It is easily recognized by its size and the charac- 
ters as given in the table. The third and fourth ventral segments 
are shorter than in the other members of this group. 
A. g;iilaris Lee. — Oblong-elliptic, jntchy black, shining, finely and .sparsely 
clothed above with whitish pubescence. Beak shining, finely punctured; three 
feebly elevated lines extending from the base to about the insertion of the an- 
tennse, the median line extending upon the front; scrobes deep, straight. An- 
tennae slender, second joint of funicle longer than the third; scape and first 
joint of funicle bright rufous, succeeding joints fuscous, verticels consisting of 
about 7-8 long, flexible hairs. Head short, conical; frontal puncture very small 
or obsolete ; occiput very finely and remotely punctured, front finely rugose. 
Eyes moderately convex, posterior margin free. Prothorax scarcely wider than 
long; sides nearly straight behind, strongly rounded and narrowed anteriorly, 
not constricted at apex; posterior angles not rounded and base not bisinuate ; 
surface densely and rather coarsely punctured on the sides, less so on tbe disc; 
pubescence somewhat condensed near the posterior angles and along the median 
line. Elytra oblong, a little wider at the base than the prothorax, feebly rounded 
on the sides and separately rounded at tip, almost twice as long as wide; striae 
finely impressed, punctures small, elongate, and not closely approximate on the 
disc, a little coarser and more closely placed on the sides; interspaces wide, flat 
finely punctulate; scntelluni densely clothed with yellowish pubescence; under- 
side of head, thorax, and sides of abdomen, densely clothed with pale, yellowish 
squamiform pubescence. Abdomen along the middle finely and sparsely pubes- 
cent and rather closely punctured ; pygidium exposed, perpendicular and coarsely 
punctured. Legs long and slender, rufo-piceous ; base of thighs, distal half of 
tibife and joints 1-3 of tarsi paler; anterior thighs with a large, elongate-trian 
gular tooth, externally to which there is a small triangular cusp; median and 
posterior femora armed with a strong single tooth. Long. 3 — 3.5 ram.; .12 — .14 
inch. 
Hab. — Virginia, West Virginia, Maryland, Michigan. 
Each elytron has a fuscous i-eflection along its disc. This species 
could only be confounded with the following, from which it is dis- 
tinguished by the characters given in the table. 
A. virgO n. sp. Plate vi, fig. 13. — Resembles gularis in form and pubescence, 
it differs as follows : Beak more densely punctured, less shining; median ele- 
vated line, scarcely attaining the base. Head opaque, densely and finely punc- 
tured, front with an impressed line. Prothorax rufo piceous. Elytra bright 
ferruginous, periseutellar space and along the suture dark piceous ; anterior tibiae 
fringed with hair along the inner margin ; anterior tibia? of male curved inward 
near the apex, and the internal angle produced in form of a broad hook. Legs 
and abdomen along the middle ferruginous. Long. 2.5 — 3.4 mm. ; .10 — .15 inch. 
Hab. — Cobb's Island, Va. Coll. E. A. Schwarz. 
Two males and one female. The female has the anterior tibiae 
simple; neither curved nor produced at the apex ; one male is much 
smaller, and has the elytra entirely piceous and the legs partly so. 
NORTH AMERICAN COLEOPTERA. 207 
A. riifipennis Lee. — Of the same oreiieral habitus as gularis, but smaller, 
and the pubescence a little more pronounced. It differs in the following char- 
acters: Piceous, elytra ferruginous. Beak shorter and stouter, opaque; striolate 
with several rows of remote punctures, lateral elevated line more prominent, 
median not extending upon the front. Antennae pale rufous, club dusky, second 
joint of funicle elongate. Eyes convex, but not free behind. Prothorax scarcely 
one-half wider than long. Elytra semi-opaque, stria? and punctures more strongly 
impressed ; interspaces slightly convex, finely rugose, each with several irregular 
rows of punctures ; scutellar space and along the suture darker; the pubescence 
on the under surface is white and as dense as in gularis ; the legs are a trifle 
stouter. Long. 2.2— 3 mm. ; .09— .12 inch. 
This species varies somewhat in size and coloration, some speci- 
mens are entirely rufous ; the pubescence, also, is more pronounced 
in some than in others. 
LeConte's description: "thorax a little longer than wide," does 
not correspond with any specimens before me, nor does the statement 
in his synoptic table of species — that the anterior thighs are uniden- 
tate. The smaller, outer cusp is well marked in all but a single 
specimen, in which it is nearly obsolete. 
Hah. — Pennsylvania (LeConte), Illinois, Texas, Florida. 
suturalis Group. 
The species belonging to this group have the anterior thighs uni- 
dentate. The ventral segments decreasing in length from the second, 
the third segment being always longer than the fourth, and this lon- 
ger than the fifth, at least in the male, except corvuhis, where the 
fifth is scarcely shorter than the fourth segment. In general, the 
species are rather sparsely pubescent, except subguttahis, all the 
femora armed with a single tooth (hind pair rautic in melancholicus), 
although the tooth of the posterior pair becomes nearly obsolete in 
specimens of stibguttatus and morulns. 'V\^e tarsi are more slender 
than in the next group, and the first joint longer than the second; 
the elytra are without a denuded fascia ; lines and spots of pubes- 
cence do not occur, except in siibguUatus, more rarely m flavicortiis. 
The species are closely related, and while it is not difficult to rec- 
ognize typical specimens, aberrant forms occur whose exact position 
it may not be always easy to determine. 
I have arranged the species as follows :

A Bolteri u. sp. — Oblong, ferruginous, thinly clothed with fine, whitish 
pubescence. Beak slender, curved, subopaque, finely pubescent and punctured, 
substriate at the base with a finely elevated, smooth median line. Antennse

Three specimens in Mr. Bolter's collection, to whom it gives me 
pleasure to dedicate this addition to our fauna. 
A. rubellii!^ u. sp. — Of the same color and similar in form to the preceding 
species, but smaller and a trifle stouter. Beak slender, curved and finely punc- 
tured ; median and a feebly elevated line each side extending from the base to 
about the middle of the beak. Antennae a little more robust, second joint of 
funicle scarcely longer than the third; joints 3-7 not longer than wide, each 
with a verticil of about six rather stiff bristles. Head dusky, very convex ;

glabrous with a few small, remote punctures, finely aud coucentrically rugulose; 
frontal puncture distinct. Eyes slightly convex, posterior margin moderately 
free. Prothorax one-third wider than long, base bisinuate; sides nearly straight 
and parallel from base to about the middle, rounded before the middle and 
strongly constricted behind the anterior margin, about three-fourths as wide at 
the apex as at the base ; surface densely and coarsely punctured, sparsely pubes- 
cent. Elytra subovate, almost one-third wider at the base than the prothorax, 
slightly widened posteriorly; sides broadly rounded to the apex, which is 
scarcely dehiscent and covers the pygidium almost completely ; strife moderately 
fine, becoming deeper and wider toward the base and sides: punctures moder- 
ately large, round, and not closely approximate; interspaces feebly convex- 
smooth and scarcely pubescent; underside with a few remote punctures, other 
wise as in BoJleri, but the pubescence is less marked, and the pygidium almost 
completely concealed by the elytra. Legs and tarsi as in that species. Long- 
2.2 ram. ; .09 inch. 
Hab. — Lake Superior. 
A unique female in my collection. It might be confounded with 
the preceding species, its nearest all}^ but differs especially in size 
and form of prothorax. From confusus it is distinguished by the 
much le.ss pronounced elytral sculpture and the interspaces being 
smooth. 
A. coilf'iisiis n. sp. — Similar in form to A. Bolter i ; rufo-testaceous, pubes- 
cence coarser and more conspicuous. Beak a little stouter and less curved ; me- 
dian elevated line very feeble, or almost obsolete; more densely and coarsely 
punctured. Antennse stouter, second joint of funicle less elongate, but always 
longer than the third. Eyes scarcely convex, posterior margin not free. Head 
a trifle more coarsely punctured. Prothorax constricted at the apex, bisinuate 
at the base. Elytra coarsely striato-puuctate, punctures large and round, almost 
or quite as wide as the interspaces near the base ; pubescence coarser and longer ; 
underside, legs and tarsi as in Bolteri. Long. 2. .3— 3 mm. ; .09 — .12 inch. 
Hub. — California, Montana, Wyoming. 
The three preceding species are very closely related, but more ex- 
tensive series are necessary, to prove them as mere variations of one 
species. Two specimens in Dr. Horn's collection, from Montana, 
which I refer to the present species, show a decided similarity to 
Bolteri in the less coarsely punctured, elytral stride, more convex 
eyes, less conspicuous pubescence and larger size. 
A. sycopliaiita Walsh.— Stouter than the preceding, dark piceons. elytra 
and abdomen ferruginous, thinly pubescent. Beak not very slender, curved, 
coarsely punctato-striolate ; median elevated line well marked, a lateral one less 
so. Antennae stout, testaceous; second joint of funicle longer than the third. 
Head convex, punctured, frontal puncture deep. Eyes feebly convex, scarcely 
free posteriorly. Prothorax transverse, two-thirds wider than long, base scarcely 
l)i-emarginate; sides rounded behind the middle, narrowed anteriorly and con- 
stricted at the apex ; surface densely and coarsely punctured. Elytra more than

one-fourth wider at the base than the prothorax ; subparallel for two-thirds their 
length and separately rounded a,t the apex, deeply and coarsely striato-punctate, 
especially so toward the base; interspaces somewhat convex, rugulose: under 
surface more coarsely pubescent, pubescence less squamiform, pygidium exposed. 
Legs and tarsi moderately slender, thighs feebly clavate, claws rather small. 
Long. 2.5—3 mm. , .10— .12 inch. 
Hab. — Pennsylvania, Illinois, Wisconsin, Massachusetts, New 
Hampshire, Michigan, Oregon, Colorado, S. California, District of 
Columbia. 
Occurs probably in all the Atlantic, Middle and Western States. 
Varies somewhat in coloration, but the elytra and the abdomen are 
always ferruginous. The anterior thoracic margin is generally red- 
dish. The legs are either bright ferruginous, or else pitchy black, 
without having observed any intermediate variations. One specimen 
in Dr. Horn's collection from South California has the elytral stria 
rather su])erficial and the punctures smaller. I have no doubt of 
the identity of this species with ^4. hcematopiis Boh. 
A. Silluralis Lee. — Similar in size and form to sycophanta, but a trifle less 
robust, pitchy black, elytra more or less ferruginous, tibife rufo piceous, tarsi 
paler, the beak is opaque, feebly striate and puntttured. Antennte, head and eyes, 
as in that species. Prothorax transverse, more strongly rounded on the sides 
behind, narrowed in front, constricted and transversely impressed behind the 
anterior margin ; surface more densely and finely punctured, base bi.sinuate. 
Elytral strife not strongly impressed; punctures small, not very close; inter- 
stices flat, more shining and very finely rugose; scutellum clothed with white 
pubescence ; under surface as in that species, but the pubescence is a little more 
dense and squamiform ; the tibise are a littb- stouter, the tarsi longer, and the 
claws larger; the tooth of the latter is also a little larger. Long. 2.7 — 3 mm.; 
.11— .12 inch. 
Hab. — Eastern and Western States. 
The red apical blotch varies greatly in extent, leaving always, 
however, the suture and scutellar space black. Larger sized speci- 
mens with the elytra almost entirely red, may be confounded with 
A. virgo, from which the i)resent species differs by its unidentate an- 
terior femora, more strongly clavate thighs and smooth rostral carina. 
From sycophanta it is to be distinguished, aside from coloration, by 
the sides of the prothorax being more strongly rounded and the 
apical constriction, the punctures also, are less coarse and less dense, 
and the elytra more shining. 
A specimen in Dr. Horn's collection from Iowa, while evidently 
belonging to the present species, has the prothorax quite coarsely, 
though very closely, punctured. The elytra are entirely ferruginous, 
with a triangular basal space dusky. 
NORTH AMERICAN COLEOPTERA. 211 
A. briiiiiiipeniiis Mann. — An oblong species, resembling the preceding 
in form and size, with the beak punctured and striate, the head puuclured, 
frontal line long ; the prothorax is a little longer than wide, very coarsely and 
densely punctured ; the elytral strise punctured, distant, not much impressed ; 
interspaces flat, smooth : the antenuse are testaceous, with piceous club; second 
joint of funicle equal to third and fourth united. Legs slender, thighs very 
feebly clavate, armed with a very small, acute tooth, almost obsolete on the hind 
pair ; tibise nearly straight. Body thinly pubescent, with some intermixed scales 
towards the sides and on the under surface. 
Hob. — Geysers, Cal. Mr. Crotch. 
I have not seen this species in nature, and therefore can only repeat 
liere the description as given by LeConte. , 
A. inelanclioliciis u. sp. — Elongate-oval, black, with scarcely any lustre, 
and clothed with a fine, squamiform pubescence, which is sparse above and more 
dense on the under surface. Beak rather stout, coarsely punctured, opaque; 
median carina almost reaching to the apex ; scrobes scarcely attaining the eye. 
Antennse rufo-testaceous, not very slender; second joint of funicle longer than 
the third, joints 3-8 transversely rounded ; clava elongate, dusky. Eyes convex, 
more widely separated above than usual. Head convex, rather coarsely punc- 
tured, with a well marked frontal fovea, and. like the beak, glabrous, except a 
few scattered scales. Prothorax conical, a little wider at the base than long 
strongly narrowed anteriorly, with the sides very feebly rounded and scarcely 
constricted at the ajjex ; surface convex, finely, densely and equally punctured, 
and sparsely covered with scale-like pubescence, each hair arising from a punc- 
ture; base feebly bisinuale. Elytra elongate, rather suddenly and about one- 
fourth wider than the base of the prothorax ; sides almost straight, gradually 
narrowed to apex, which is but slightly dehiscent; strife fine, feebly impressed ; 
punctures small, elongate and rather remote ; interspaces flat, or nearly so, and 
having some lustre, remotely puuctulate, sparsely pubescent; underside : pectus 
rather densely, abdomen more sparsely punctured, rather densely clothed with 
pale scales. Legs slender, thighs feebly clavate, anterior and middle with a small 
sharp tooth, posterior mutic; tibiae slender, rufo-piceous, anterior and middle 
' straight, posterior feebly bisinuate and dilated internally at the tij) ; tarsi slender, 
paler than the tibiiP. Long. 3.2 mm. ; .13 inch. 
Hah. — Victoria, Vancouver. 
Two males and one female, collected by my friend, F. H. Wickham, 
at the above locality. The female has the beak more shining and 
slender, the hind tibire less bisinuate and scarcely produced at tip. 
On account of the squamiform pubescence, which is readily removed, 
this species might be referred to the sqnwnosvs grou|), with which, 
however, it has not the least affinity. Abraded specimens resemble 
more nlgrimis, from which it differs by the finely punctured protho- 
rax and shorter fifth ventral segment.

twice as wide as long, bisinuate at the base and moderately constricted at the

sides nearly straight, separately rounded at apex ; strise fine on the disc, becom- 
ing wider and more deeply impressed on the sides; punctures small, slightly 
elongate and remote, larger and more closely approximate on the sides; inter- 
spaces shining, plane on the disc, more convex towards the sides and apex, fiuely 
rugose, scutel and intra-humeral spot densely white pubescent; underside re- 
motely punctured. Legs stouter than in suturalis ; thighs more strongly clavate. 
anterior and middle tibipe bisinuate internally, posterior straight; tarsi slender,

Hab. — Southern States (Patin ?). 
A specimen in my collection, taken in this neighborhood (Hazleton, 
Pa.), measures scarcely 2.5 mm., but does not differ otherwise. Two 
specimens from Texas in Mr. Ulke's collection are a little less robust, 
with two interrupted lines of condensed pubescence on the elytra, 
thereby forming some similarity to subguttatus. From nigrinns, with 
which the present species might be confounded, it is to be distin- 
guished by the less coarsely and less densely punctured prothorax, 
testaceous anteunte and less slender legs. 
A. nioruliis Lee. — Black, or piceous, robust and convex; pubescence fine, 
sparse, a trifle more dense on the under surface. Beak moderately slender, 
punctured, shining towards the apex, median carinate line distinct, feebly 
striate from the base. Antennae rather robust, rufopiceous ; scape and first joint 
of funicle rufous, second joint of funicle longer than the third, joints 3-7 trans- 
verse, outer joints wider. Eyes feebly convex and scarcely free behind. Head 
globo.se, occiput scarcely, front more distinctly punctured ; frontal puncture 
rather large: a transverse, impressed line on a level with the superior margin 
of the eyes. Prothorax scarcely one-half wider than long, moderately narrowed 
anteriorly, scarcely constricted at the apex ; sides almost straight behind, feebly 
rounded before the middle, base not bisinuate; surface coarsely and rather 
densely punctured. Elytra about one-third and rather suddenly wider at base 
than the prothorax and less than one-half longer than wide ; the sides, seen from 
above, appear slightly emarginate behind the humerus, due to a feeble bulging 
outward of the ninth and tenth interspaces, rather suddenly narrowed to the 
apex, which is separately rounded and widely dehiscent, leaving the pygidiun) 
freely exposed ; strife fine, punctures moderately large and approximate ; inter- 
spaces flat, subopaqne and rather strongly rugose ; under surface punctulate. 
Legs not very slender, thighs moderately clavate, all armed with a small, acute 
tootlv; tibife slightly widened toward the apex, anterior and middle scarcely 
biemarginate, posterior straight ; tarsi moderately slender, tooth of claw long and 
slender. Long. 2.6 — 2.8 mm.; .10— .11 inch.

Hah. — California. 
Oulv two female specimens in Dr. Horn's collection are before me. 
Bears a striking resemblance to Epiinechus niimicus, described further 
on, from which, indeed, it cannot be distinguished, except by the 
toothed claws. 
Since writing the above I have received a specimen from Dr. Horn, 
which has entirely the coloration of a typical A. siduralis, the elytra 
being bright rufous with the exception of a triangular basal space ; 
it is easily recognized, however, by the form of the prothorax and 
the less shining elytra. 
A. corvtllus Lec.--Eather robust, oval, black shining; pubescence rather 
long and coarse, but sparse and easily removed. Beak moderately slender, punc- 
tured with well-marked median carina; scrobes curved, somewhat approximate 
beneath and directed against the lower angles of the eyes. Autennje stout, rufo- 
piceous; scape paler, second joint of fuuicle scarcely longer than the third, 
following joints gradually wider, verticels consisting of stiff, bristle-like hairs. 
Eyes feebly convex and slightly free behind. Head convex, occiput impunc- 
tured, front with a few punctures and a well-marked fovea. Prothorax trans- 
verse, more than one-half wider than long, strongly rounded on the sides and 
gradually narrowed to apex, which is feebly constricted ; base scarcely bisinuate, 
surface coarsely, but not densely punctured. Elytra about one-fourth wider at 
the base than the prothorax ; humeri rounded ; sides a little widened to behind 
the middle, separately rounded at tip, leaving the pygidium freely exposed ; strise 
deeply impressed, wide; punctures large, not closely approximate; interspaces 
convex, smooth, with small, remote punctures; scutellum white pubescent: 
underside remotely punctured, pubescence more dense. Legs slender, thighs 
feebly clavate, all armed with a small, acute tooth ; tibise almost straight, and at 
the apex, like the tarsi, brownish. Long. 1.5 — 2.2 mm. ; .06 — .09 inch. 
Hab. — Pennsylvania, Massachusetts, District of Columbia, Illinois, 
Wisconsin, Michigan, Texas, Arizona. 
Easily recognized by its small size, shining black color, coarsely 
punctured prothorax and spar.se pubescence. The pubescence is 
easily rubbed off, giving the in.sect a still more shining appearance, 
and on superficial examination, might give rise to confusion. Speci- 
mens are before me of a l)ro\vn color, probably due to their being 
immature. 
A. siibguttatus n. sp. — Elongate-oval, piceous, more slender, but other- 
wise closely allied to flavicornis, from which it differs in the following charac- 
ters: Pubescence coarse, dense and white. Beak more slender and shining, 
finely and less closely punctured ; median carina more distinct, shining, and ex- 
tending to the frontal puncture. Head not concentrically rugulose, second joint 
of funicle scarcely longer than the third. Prothorax less rounded on the sides, 
which are almost straight behind with the hind angles rectangular: apex not 
constricted, punctures smaller and remote on thedi.sc, crowded on the sides; a

median vitta, wider at the base of condensed pubescence. Elytral striae gener- 
ally more deeply impressed, two interrupted lines of condensed pubescence, ex- 
tending from the sides to the second interspace, where they unite; the space 
enclosed between these lines is not denuded, densely clothed on the underside 
with white ])ubescence; pygidium freely exposed. Legs slender, rufo-piceous. 
thighs feebly clavate, tooth small, posterior almost obsolete: anterior and middle 
tibife scarcely bisinuate internally. Long. 2.7 mm. ; .11 inch. 
Hab. — Florida, District of Columbia. 
A specimen in Mr. Ulke's collection, from District of Columbia, 
differs from the typical form by the ])ul)escen('e being pale yellowish, 
sparser and less coarse. 
This species might possibly be referred to the dgaatus group, with 
which, however, it has no close relationshi]i ; the first and second 
ventral segments are relatively shorter, and there is no denuded 
elytral fascia. Dr. LeConte indicated this species under A. scutella- 
tus Gyll. (Proc. Amer. Phil. Soc vol. xv, p. 199), but failed to de- 
scribe it. 
sig-natus Grotip. 
This group contains species of rather small size, and presenting a 
sin)ilarity of habitus which makes them easy of recognition. They 
agree with those of the preceding group in the abdominal formation; 
the first and second ventral segments, however, are generally longer 
and nearlv equal in length, the gradual decrease in length commen- 
cing with the third segment, instead of the second, as in that group. 
The elytra have a post-median denuded patch or fascia, surrounded, 
in the fresh state at least, by spots or lines of pubescence. They 
differ very little in sculpture, and are to be distinguished rather by a 
general assemblage of characters and habitus. The first two tarsal 
joints are equal, or nearly so. 
The following table, supplemented by the s))ecific description, will 
enable the student to identify his species : 
Elytral interspaces equal, or nearly so. 
Front foveate. 
Larger and more robust, second joint of funicle distinctly longer than the 
third: prothorax strongly rounded on the .sides. 
Frontal fovea small, punctiform ; pubescence fine, inconspicuous.

A. signatus Say. Plate vi, fig. 15. —Robust, oval, piceous ; elytra red, de-

Beak moderately slender, feebly curved, subopaque and rather densely striato- 
pnnctate: median carina smooth, distinct. Antennse testaceous, club darker, 
funicle rather stout, outer joints distinctly wider, second joint distinctly longer 
than the third, but not slender; joints 3-7 transversely rounded. Eyes moder- 
ately convex, free behind. Head convex, occiput somewhat shining, front with 
a few remote punctures, finely and indistinctly rugulose, frontal puncture dis- 
tinct. Prothorax wider than long, moderately narrowed in front; sides not 
strongly rounded, feebly constricted at the apex and transversely impressed 
behind the anterior margin ; surface rather coarsely and densely punctured, 
pubescence condensed along the median line. Elytra less than one-fourth wider 
at the base than the prothorax and about one-half longer than wide, a little 
widened to behind the middle; sides feebly rounded ; strise impressed, punctures 
moderately large, close set and becoming smaller towards the lateral margin ; 
interspaces slightly convex, shining with an irregular row of fine punctures; 
the denuded fascia extends from the side to the third interspace, another de- 
nuded spot on the second interspace ; scutellar space and along the suture darker ; 
scutellum and intra-humeral spot densely pubescent. Thorax underneath more 
densely clothed with white, squamiform pubescence. Abdomen sparsely pubes- 
cent, segments transversely strigose, first and second segments rather long. Legs 
slender, femora feebly clavate, piceous, all armed with a sharp, well-marked 
tooth ; tibise paler, anterior feebly bisinuate, middle and posterior nearly straight ; 
tarsi pale, first joint elongate. Long. 2—2.9 mm. ; .08— .12 inch. 
Hab. — Atlantic slope. 
Varies considerably in size, and still more so in coloration, from 
pale testaceous to almost pitchy-black ; the latter variation might 
readily be mistaken for the next species, from which it differs by the 
less rounded prothorax and stouter antennal funicle ; the beak also 
is more densely punctured and less curved. The following variety 
is well marked, and deserves special consideration : 
Var. pallidus. — Testaceous ; head dark piceous ; rostrum and 
pectus infuscate. Prothorax nearly twice as wide as long ; the scu- 
tellar space is scarcely darker. I would consider this to be hidg- 
iintus Gyll., but the expression — " thorax latitudine baseos paulo 
216 WILLIAM G. DIETZ, M. D. 
hrevior," does not apply to the form under consideration, and prob- 
ably refers to a pale variety having the typical form of thorax. 
Occurs in Louisiana, Georgia, Florida, Maryland. 
.4. coii!iiiinilis u. sp. —Agrees with signatus in size and general habitus, but 
(liflFers in the following characters: Color uniformly pitchy-brown or black. 
Beak distinctly curved, less densely punctured and a little more slender ; funicle 
of antennae less robust, outer joints scarcely wider; second joint more elongate 
and slender. Head opaque, rugulose. Prothorax, with the sides, more strongly 
rounded, and more strongly narrowed anteriorly; denuded fascia always reach- 
ing to the first interspace ; tibife, especially middle and posterior, more widened 
toward the apex. Long. 2.5 — 2.8 mm.; .10 — .11 inch.

somewhat shining; median elevated line almost obsolete, feebly striate at base. 
Antennae rather stout, scape and first joint of funicle paler; second joint elon- 
gate, outer joints but litttle wider. Eyes flattened, scarcely free behind. Head 
short, convex, remotely punctured, each puncture l)earing a whitish hair, front 
sulcate. Prothorax wider than long, moderately narrowed anteriorly; sides 
rounded from the base, scarcely constricted at the apex; coarsely but not very 
closely punctured, base bisinuate. Elytra more than one-fourth wider at base 
than the prothorax ; sides feebly rounded ; striae deeply impressed, punctures 
coarse, closely approximate; interspaces convex, finely rugose and each with 
several irregular rows of piliferous punctures; surface rathei- dull, without 
lustre; the fascia extends from the side to the third or second interspace; side 
jjieces of thorax densely clothed with white scales. Abdomen more thinly pu- 
bescent, the fifth ventral segment is not shorter than the fourth, pygidium freely 
exposed, densely xnmctured. Legs not very slender, thighs moderately clavate, 
armed with an acute tooth. Long. 2.3—2.5 mm. ; .09 — .10 inch. 
Hab.—C. 111. (Hamilton), Fla., Ga., Texas (Dr. Horn). 
Differs from signatus by its coarse pubescence, larger, elongate 
frontal fovea and uniform brown color ; the elytral fascia is wider, 
extending farther anteriorly, and is not interrupted. 
Dr. Hamilton's specimen has the prothorax more finely and 
densely punctured, and the posterior thighs not toothed. It may 
possibly be distinct, but as it agrees otherwise, I do not feel justified 
in establishing a new species on a single specimen.

Varies in coloration ; fresh specimens have the elytra more bright 
red, which in dried specimens changes to a dark brown or even 
blackish color. The denuded spot can generally be recognized by 
its darker color, and being surrounded by a line of pubescence, 
which is liable, however, to abrasion. AVhy Prof Riley should con- 
sider this species identical with signatas (Agric. Report 1885, pp. 
276-282) I cannot understand, for, aside from the difference in length 
of the second joint of funicle which is always evident in fresh and 
can be demonstrated on old specimens that have been relaxed, the 
present species is less robust, thorax less rounded on the sides, and 
suture always darker. According to Dr. John Hamilton it is rarely 
found after the first week in June, whereas signatus is found always 
during the whole of Summer on various plants and shrubs, while 
the former is generally taken on Huckleberry.

Two specimens in Mr. Scliwarz's collection. A very distinct spe- 
cies, readily recognized by its vestiture consisting of scales inter- 
mixed with fine pubescence and the double elytral spots, the anterior 
of which is semi-annular in shape; superficially, it very much re- 
sembles light colored specimens of signatus, but is smaller. The 
first ventral segment is rather shorter than usual in this group, and 
fifth segment of the male does not appear to be shorter than the 
fourth. 
A. siilcifroilS Lee. — Subovate, dark piceous, shining, thinly clothed with 
white pubescence. Beak not slender, shorter than head and thorax, feebly 
curved, subopaque, punctured, median Hue feeble. Antennae rather slender,

straight, anterior feebly bisinuate internally ; tarsi less slender, first three joints 
bioad, not longer than wide, fourth joint less slender and a little shorter than 
in the three preceding species. Long. 2 — 2.2 mm. ; .08 — .09 inch. 
Hab. — Mi.ssouri, Illinois, District of Columbia, Pennsylvania. 
Similar in size and habitus to corvuliifi, from which it differs by 
the prothorax being more strongly rounded on the sides and less 
coarsely punctured, the denuded elytral fascia and the tarsi shorter 
and more robust. From consimllis, of the present group, which it 
resembles in appearance, it diflfers by its smaller size, shorter and 
relatively stouter beak and shorter tarsi ; the first two joints of the 
funicle are also relatively shorter than in that species. It might also

be confounded Avith the dai'k variety of mnsculus, from which it can 
readily be distinguished by the shorter beak and tarsi, and the second 
joint of fuiiicle distinctly longer than the third. 
Comparison with the type of this species, in the LeConte collection 
at Cambridge, was kindly made by Dr. G. H. Horn. 
A. sexguttatus n. sp. — Oblong, rufo-te^taceons, pubescence whitisli, fine 
and sparse. Beak not slender, curved, about as long as head and thorax, finely 
punctured, somewhat shinine-, with a fine, elevated median line. Aiitenufe 
moderately slender, second joint of fuuicle very little longer than the third, 
joints 3-7 transverse, club dusky. Eyes feebly convex ]iosterior margin free 
and more than usually approximate upon the front. Head convex occiput finely 
alutaceous, dusky; front with several rows of piliferous punctures and with a 
long and distinct suhnis between the eyes. Prothorax wider than long, sides 
rounded, broadly but not strongly constricted at the apex, transversely im- 
pressed in front, rather finely and not very densely punctured, except on the 
sides, where the jainctures become a little more crowded and coarser. Elytra 
less than one-fourth wider at base than the prothorax, suboval, a trifle wider 
posteriorly ; sides feebly rounded ; striae impressed, punctures moderately large, 
round and closely approximate; interspaces slightly convex, with an irregular 
row of small punctures and somewhat rugulose; scutellar space and along the

humeral spot and a spot on the anterior and posterior margin of the denuded 
fascia, on the fourth interspace more densely pubescent, between the latter two 
spots is a dark line; underside and legs thinly pubescent and remotely punctu- 
late. Legs not very slender, thighs rather strongly clavate, anterior with a large, 
triangular tooth, middle with a small tooth, posterior thighs mutic; anterior

This species greatly resembles rufipennis of the gnlaris group, but 
is smaller, and differs further by the front being sulcate, the anterior 
thighs with a single tooth and the posterior thighs mutic. 
The first two ventral segments are relatively shorter in this than 
the other species of this group, and the spots of condensed pubescence 
on the elytra give it a peculiarly striking appearance. 
A. intei'Stitialis u. sp. — Elongate, subovate, black ; pubescence very fine 
and scant above ; side pieces of thorax and sides of abdomen densely clothed with

ond joint of funicle rather slender, elongate ; joints 3-7 rounded, outer ones but 
little wider. Eyes scarcely convex and but indistinctly free behind. Head sub-

nigrinus Group. 
The species of this group differ from those of the two preceding 
ones by the fifth ventral segment of the male being longer than the 
fourth, the third and fourth equal in length, or very nearly so. In 
some specimens the fifth ventral is not longer than the fourth ; in 
this case, however, the third and foui'th are always equal and shorter 
than in the two preceding groups. 
The species are closely related, and are to be distinguished as 
follows : 
All the thighs armed with a single tooth. 
Black ; front foveate. 
Eobust; anterior and middle tibiie curved inward near the apex; first joint 
of anterior tarsi twice as long as the second ; femoral tooth spinifonn. 
ebeiiiiiiis. 
Less robust; tibiae straight, first tarsal joint scarcely longer than the second ; 
femoral tooth acutely triangular iiigriiiiis. 
More elongate; tibise curved near the base; first tarsal joint longer than the 
second; femoral tooth large albopilosus. 
Piceous or blackish, with seneous lustre ; front sulcate between the eyes. 
Pubescence uniform; elytra without denuded fascia or lines of condensed 
pubescence. 
Larger and more robust; base of middle and hind thighs and distal half 
of tibia:' and tarsi, honey-yellow xanthoonenius. 
Smaller and more slender; legs piceous, tihite and tarsi paler..8eneolus. 
Elytra very coarsely .striato-punctate with partially denuded fascia and lines 
of condensed pubescence faber. 
Posterior thighs mutic, elytra with denuded fascia. 
Less robust, front sulcate, upper surface rather densely clothed with squami- 
form pubescence, denuded fascia ill-defined effetns. 
Very stout, front foveate, upper surface less densely pubescent, denuded fascia 
well defined sctitellatus. 
NORTH AMERICAN COLEOPTERA. 221 
A. ebeiiinus n. sp. — Robust, ovate; lilack, with a faint seueotis lustre and 
rather conspicuously clothed with white pubescence, which is more dense on the 
under surface. Beak long and slender, feebly curved, punctured, scarcely striate. 
Antennae long and slender, scape and first joint of fuuicle rufo-testaceous, re- 
mainder rufo-piceous; tirst joint of funicle long, not very stout, second joint 
longer than the third, outer joints scarcely wider, club rather loosely articulate. 
Eyes somewhat prominent, convex, posterior margin free. Head convex, occiput 
impunctured, front finely punctured and pubescent, especially between the eyes, 
frontal fovea elongate, rather deep. Prothorax fully one-half wider than long 
and nearly twice as wide at the base than at the apex, latter scarcely constricted ; 
sides regularly rounded from the base, latter biemarginate ; surface densely and 
rather coarsely punctured, punctures subcoufluent on the sides, each bearing a 
whitish hair; scutellum oval, densely pubescent. Elytra shining, one-fourth 
wider at the base than the prothorax; oval, sides feebly rounded; striae im- 
pressed, punctures round, small and closely approximate: interspaces slightly 
convex, each with about three iri-egular rows of fine, piliferous punctures; pu- 
bescence evenly distributed, except a small intra-humeral spot, which is more 
densely pubescent; underside densely punctured, pubescence scarcely as long as 
above; pygidium fully exposed, punctured. Legs long and slender, thinly pu- 
bescent; femora slender, feebly clavate, armed with a spiniform tooth; tibiae 
long and slender, sinuate internally, anterior and middle curved inward near 
the apex, posterior straight ; tarsi slender, first joint of anterior almost twice as 
long as the second ; claws armed with a long slender tooth. Long. 3.5 mm. : 
.14 inch. 
Hab. — Lower California; exact locality not stated. 
A % and 9 specimen in Mr. Dike's collection, who received it 
very recently from the above locality. 
The raesosternum is moderately wide between the coxse, where it 
ends in an elevated, transverse ridge, and slopes very gradually in 
front. The third and fourth ventral segments are of equal width, 
and the fifth distinctly longer than either ; the pygidium is freely 
visible from below. 
This species, although very distinct, is closely allied to fiavicornis, 
nigrinus and albopilosus. It resembles flaviconm so closely that, if 
viewed from above, it cannot be distinguished, except by its somewhat 
greater size ; the abdominal formation, however, is strikingly different, 
the beak, legs and tarsi much more slender; the first joint of the 
anterior tarsi twice as long as the second, while equal in Jiavicomis. 
From the next species it difl^ers by its being more robust, the beak 
more slender, thorax less coarsely punctured, the femoral tooth spini- 
form, the anterior and middle tibise curved near the ajiex, and the 
more slender tarsi with the first joint nearly twice the length of the 
second. The elytra, also, are a little more strongly striato-punctate, 
and the pubescence much more conspicuous than in that species. 
222 WILLIAM G. DIETZ, M. I). 
From albopilmus it dirters by its stout form, the elytra less coarsely 
striato-piinctate ; the femora are more slender, the tooth smaller, and 
the tibi?e are not curved near the base. 
A. nigriilUS Say.— Siibovate, robust, pitchy-black, thinly clotlu-fl with 
fiue, whitish pubescence. Beak not very slender, opaque, coarsely punctured 
with the median elevated line distinct, shiuing, and striate each side from the 
base to about the middle ; scrobes slightly curved inferiorly and rather superficial. 
Antennae inserted about the middle, slender, piceous : first joint of funicle ro- 
bust, second elongate, slender; following joints gradually wider. Eyes feebly 
convex and scarcely free behind. Head short, spherical, with a fev\-, rather 
large, remote punctures, front deeply foveate. Prothorax wider than long, sides 
broadly rounded from the base, moderately narrowed anteriorly and scarcely 
constricted at the apex ; equally, densely and coarsely punctured. Elytra oval, 
one-third wider at the base than the prothorax and about one-half longer than 
wide, finely striato-punctate, punctures not approximate: interspaces flat, re- 
motely punctulate; seutellnm densely clothed with white pubescence; under 
surface a little more coarsely and densely pubescent; side pieces of thorax and 
abdomen with a few remote punctures. Legs slender, femora feebly clavate, 
armed with a small, acute tooth; tibiaj rather slender, nearly straight; tarsi long 
and moderately slender, fringed with white hair. Long. 3 mm. ; .12 inch. 
Hah. — District of Columbia, North Carolina, Louisiana, Virginia. 
Not unlike flavlcornis, from which it differs in the abdominal for- 
mation, more coarsely punctured thorax and pitchy-black antennae. 
Might also be confounded with morxdns, but is more robust and less 
convex, and the elytra more shining. Its resemblance to ehenbws 
has been noted under that species. 
,4. albopilosus n. sp.— Oblong-elliptic; black, somewhat shining, not 
densely clothed with long, white pubescence. Beak longer and more slender 
than in nigrinus ; smooth, shining, sparsely and finely punctured ; substriate from 
the base to about the middle, median elevated line well marked, shining; .scrobes 
straight. Antennje slender, inserted about two-fifths ( '^ ) or one-half ( 9 ) fi'om 
the apex ; rufo-testaceou.s, first joint of funicle long and less stout, second joint 
a little more slender, elongate: following joints scarcely wider than long. Eyes 
almost flat, not at all free behind. Head subconical, somewhat shining, and 
rather coarsely punctured, frontal fovea deep. Prothorax a little wider than 
long, rather strongly narrowed in front and feebly constricted at the apex, sides 
broadly rounded; surface closely, but not very coarsely punctured ; base nearly 
straight each side. Elytra oblong, shining, but little wider at the base than the 
prothorax. feebly rounded on the sides and gradually narrowed to the tip. coarsely 
striato-punctate, punctures rounded, approximate; interspaces moderately con- 
vex, punctured; under surface rather coarsely, but not very closely punctured, 
more densely and coarsely pubescent. Legs long and slender, femora clavate, 
armed with a triangular tooth, which is larger and very prominent on the ante- 
rior pair; tibise slender, anterior strongly curved near the base and bisinuate 
internally ; tarsi long and slender. Long. 2.8—3.3 mm. : .11— .13 inch.

on the sides. Elytra broadly oval, strije deeply impressed, punctures rather 
large and closely approximate: interspaces convex, rugulose and irregularly 
punctured ; scutellum densely pubescent ; side pieces of thorax and abdomen 
finely and remotely punctured. Legs slender, thighs clavate, all armed with a

This species has been confounded with fiavicornis, from which it is 
easily distinguished, aside from structural differences, by the colora- 
tion of the legs. It varies somewhat in sculpture. A specimen in 
my collection which I refer, with some hesitation, to the present spe- 
cies, has the elytra rather finely punctato-striate. It is closely related 
to the two following species. 
A. ieneoItiN n. sp. — Closely allied to the preceding, but is smaller and 
much le.ss robust, blackish with teneous lustre ; pubescence white and fine. Beak

Hab. — Vii'ginia. 
A single 9 in my collection found among a lot of loose material 
sent me years ago by Mr. H. Ulke, of Washington, and labeled 
" Virginia." 
This species is an exact reproduction of A. ungularis in form, color 
and pubescence, but for the 7-jointed funicle, absence of elytra! 
-fascia and very slender tooth of claw, it could not possibly be dis- 
tinguished. The fifth ventral segment is longer than the preceding. 
A. orchestoides n. sp. — Elongate-ovate, black, sonjewhat shining, and 
very thinly clothed with fine, white pubescence, which is scarcely more dense 
on the under surface than above. Beak rather stout, slightly widened toward

The anterior coxre are more prominent than usual, and the ventral 
sutures curved slightly backward at the sides ; the beak, also, in re- 
pose seems to be deflected further backward than is usual among 
other members oi' this tribe.

This species, at once recognized by its pale testaceous color and 
dark elytral spot, lias a remarkable similarity to Nanophyes trans- 
versifs Aube of Southern Europe, and which, according to Desbro- 
chers,* was described by Chevrolat as Anthonomus juniperi. 
squamosus Group. 
Contains all those species with 7-jointed funicle, in which both the 
upper and under surface are predominantly clothed with scales. 
The scaly vestitui-e, while dense in most of the species, is sparse and 
intermixed with a fine pubescence in some. The scales also vary 
from almost round to very elongate, piliform. The ventral segments 
are less unequal than in the majority of the pubescent species. Some 
of the vittate forms show great similarity to the species of the sub- 
genus Cneraocyllus, from which they differ merely by the hind tibiae 
of the male not being dissimilar from those of the female. 
The species may be tabulated as follows : 
Stout species ; all the femora armed with a tooth. 
Anterior thoracic opening very oblique, prosternum short in front of the coxffi. 
Elytra without transverse, partly denuded fascia. 
Beak and antennse slender; legs reddish, or rufo-piceons. 
Larger; beak long and very slender; first and second joint of funicle 
elongate. 
Not densely clothed with scales, which are more or less piliform ; color 
pitchy-black, legs rufo-piceous ater. 
Densely clothed with oval scales, reddish to rufopii-eous. legs rufous. 
squamosum. 
Smaller; beak shorter and less slender, first and second joint of funicle 
less elongate tectus.

the third, legs dark piceous !«quaiiiiiIaluM. 
Elytra with dark, transverse, partly denuded fascia iiiolucliiiiiis. 
Anterior thoracic opening less oblique; prosternum more elongate in front of 
the coxae. 
Prothorax strongly constricted at the apex ; beak and antejinse stouter, 
second joint of antenna; scarcely longer than the third. ..rilfipes. 
Prothorax not constricted at the apex; beak and antennae slender, second 
joint of funicle longer than the third disjuuctus. 
More or less elongate, hind femur not toothed. 
Scales piliform ; elytra wider at the base than the prothorax. 
Eyes as widely separated above as the width of rostrum at the base, more 
elongate; prothorax scarcely wider than long. 
Second joint of funicle longer than the third, scales very small and less 
dense intiriuus.

tennse slender, rufous, clava darker; first and second joint of funicle long and 
slender, following joints subturbinate, not wider than long, club densely pubes- 
cent. Eyes feebly convex, not free behind ; front somewhat flattened, obscurely 
impressed transversely, fovea elongate. Piothorax a little wider than long, 
sides broadly rounded and narrowed from base to apex, latter constricted ; base 
scarcely emarginate each side; surface densely, but not coarsely punctured, each 
puncture bearing a scale, which become broader and larger along the median 
line, on the sides and under surface ; scutel densely clothed with white scales. 
Elytra rather suddenly and about one-fourth wider at the base than the protho- 
rax, suboval, a trifle wider behind ; strise fine, punctures elongate, approximate; 
interspaces almost flat, very slightly roughened ; scales rather piliform, irregular 
in width and entirely concealing the derm, those of the alternate interspaces, 
especially the fourth and sixth, paler; underside of pectus densely covered with 
grayish white scales; abdomen coarsely pubescent. Legs slender, rufo-piceous ; 
femora clavate, armed with a sharp, triangular tooth ; tarsi slender, paler. Long.

Hub. — California, Oregon. 
Closely allied to squcmiosu-i, from which, indeed, it differs but little 
structurally, except in the form and density of the scales. Comparison 
will show at once that it should not be placed among the pubescent 
species. 
A. sqiiauiOSllS Lee. — Oval, reddish brown to piceous, densely covered with 
grayish white, or pale yellowish, oval scales ; otherwise, like the preceding spe- 
cies, from which it diff"ers, aside from coloration, form and density of scales, as 
follows: Beak reddish brown, more shining, less punctured and scarcely striate. 
Prothorax more distinctly wider than long. Elytra scarcely one-fourth wider 
than the prothorax at its base, humeri more oblique; striae and punctures more 
concealed by the scales. Legs reddish brown. Long. 3.5 -4.5 mm.; .14 — .18 inch. 
Hab. -Kansas, Colorado, New Mexico, California, Nebraska. 
Varies considerable in form, coloration and density of the scaly 
vestiture. The alternate elytra! interspaces are paler in some speci- 
mens, giving them a vittate appearance, more or less marked. 
Two variations, deserving special mention, occur : 
Var a. — Scales uniformly grayish white, less closely adherent to 
the derm. Each elytral interspace with an irregular row of suberect, 
setfe-like hair.

Two males in my collection. A very distinct species ; differs from 
tectus by its smaller size, short and robust beak, and the anterior and 
middle tibife strongly bisinuate and subangulate along the internal 
margin ; also closely allied to rufipes Lee. by the form of rostrum 
and tibise, but is smaller and the prosternum is short in front of the

Very distinct ; might, perhaps, with equal propriety be referred 
to the pubescent species, the whole habitus, arrangement of elytral 
vittse, however, place it unmistakably in the present group, while 
the conspicuous, partially denuded elytral fascia, distinguishes the 
present from all the other members of the same. 
A. rufipes Lee. — Oval, pitchy-black, antennae and legs ferruginous, thinly 
clothed above with grayish scales intermixed with fine pubescence, under surface

Hah. — Illinois (Dr. Hamilton and A. Bolter), Iowa. 
The identification of this species, which was donbtf'ul from the 
description as given by LeConte, has been verified by my friend, 
Dr. Horn, by comparison with the type in the author's collection at 
Cambridge. 
The difl^erentiation from squmnulatus has been referred to under 
that species.

inch. 
Hab.— Oregon (H. Ulke), Colorado (Dr. Horn). 
Two males and one female are liefore me. Closely allied to hirtus, 
but is less densely scaly above and the .second joint of funicle is dis- 
tinctly longer than the third. Not unlike A. effetvs in form and 
coloration, but is a little more elongate, and the vestiture consits of 
true scales, while in the former it consists of suberect, scale-like pu- 
bescence. 
A. liirtiis Lee— Of the same form and sculpture as the preceding, but a 
little smaller and densely covered with grayish or ochreous scales, which com- 
pletely conceal the color of the derm, which varies from rufo-ferruginous to 
pitchy-black. Antennae and legs rnfo-ferrueinous ; the beak is more slender and 
scarcely striate or punctured ; the second joint of funicle is scarcely longer than 
the third; three thoracic vittte and along the suture paler, each elytral inter- 
space with a row, more or less irregular, of short, suberect, piliform scales. Legs 
and tarsi as in mnrinus. Long. 2.8 — 3 mm.; .11 — .12 inch. 
Hab. — California, Arizona, Utah. 
The scales vary in form from broadly oval to piliform. The sub- 
erect, scale-like hairs of the interspaces are almost obsolete in some 
specimens. Resembles also the next species.

preceding, rufo-piceous, upper and under surface densely clothed with ochreous, 
lanceolate, suberect scales. Beak a little shorter and less slender than in hirtus,

cent, median elevated line not distinct. Antennse ferruginous, moderately slen- 
der; second joint of funicle longer than the third. Eyes somewhat convex, less 
widely separated above than the base of the beak. Head short, punctured, and 
densely pubescent; frontal fovea elongate. Prothorax about one-half wider than

Two females in Mr. Ulke's c(jllecti()n. 
Might easily be mistaken for hirtiis; in fact, the descriptive phrase, 
as given by LeConte of that species, " densely clothed with coarse, 
scarcely squamiform, ochreous pubescence," applies far better to the 
species under consideration ; it is, however, less elongate, the eyes 
slightly encroaching upon the front, the prothorax distinctly wider 
than long, the thighs more strongly clavate, and both anterior and 
middle armed with a tooth. The peculiar curved projection of the 
terminal hook of the anterior and middle tibia? I do not remember 
of having observed in any other species. One of the specimens has 
a strongly marked, oblique impression each side of the prothorax. 
The unusual occurrence of this kind of sculpture in the present 
tribe is no doubt due to some disturbance in the earlier stages. 
A. pauperculii!« Lee. PI. vi, fig. 18. — Oblong-elliptic, rufo-piceous, densely 
clothed above and beneath with large, round, grayish white scales, mottled with 
brown on the upper surface. Beak moderately long, not slender, regularly

line distinct, pubescent at the base. Antennae stout, rufous; first joint of funicle 
very stout, second not elongate, outer joints gradually wider, rounded, and like 
the club, darker. Eyes moderately convex, posterior margin not free. Head

ally narrowed from the base, latter feebly bisinuate; sides broadly rounded, 
broadly, but feebly constricted at the apex ; surface coarsely and closely punc- 
tured, punctures concealed by the scales, a broad brown stripe each side of the 
median line, latter and sides paler. Elytra oblong-oval, a little wider at the base 
than the prothorax ; huujeri oblique, sides broadly rounded to apex ; stripe wide, 
impi-essed, punctures moderately large, not closely approximate and concealed 
by the scales, which are predominantly brownish in color; scutellum, periscu- 
tellar space, an irregular oblique stripe extending from humerus to about the 
middle of the suture, and an indistinct, transverse, posterior fascia, paler. Legs 
and tarsi long and slender, pale rufous; thighs slender, infuscate about the mid-

less pronounced, pubescence conspicuous and somewhat condensed along the 
median line; the elytra are less conspicuously wider at the base than the pro- 
thorax, the striae a little more coarsely punctured, the first and second not more 
so than the rest; the denuded fascia is more evident, and extends from the sides 
to the suture ; under surface more densely pubescent. Legs a little more slender ;

The elytra are generally paler, testaceous, but a s|)ecimen in Mr. 
Dike's collection is of a dark brown color, thereby greatly resembling 
latmscalus.

dirty white, cuneiform scales, which are a little larger and more condensed on 
the underside of the thorax. Beak long and slender, slightly widened toward

together. Eyes nearly flat, scarcely free behind. Head convex, finely and re- 
motely punctured, rugulose and thinly pubescent; frontal fovea distinct, elon- 
gate. Prothorax much wider than long, markedly narrowed from base to apex, 
the latter feebly constricted, sides rounded; .surface rather convex, densely and 
rather coarsely punctured, each puncture bearing a piliform scale, which, how- 
ever, become broader on the sides; base scarcely emarginate each side. Elytra 
but little longer than wide and about one-fourth wider at the base than the 
prothorax, feebly rounded on the sides and rapidly narrowed to the tip, strongly

Hab. — Nebraska, Montana, District of Columbia. 
A specimen in Mr. Bolter's collection and one in my own, which 
I received from that gentleman some years ago, differ from the above 
description in the following points : Larger, the scales are larger, 
white; antenna3 entirely testaceous, joints 2-4 of funicle equal in 
length, fifth and sixth wider. Prothorax depressed each side at the 
base, punctures smaller and more remote ; elytra more finely striato- 
punctate. Long. 2.2 mm. ; .09 inch. Hab. — Montana. Both speci-

mens are badly abraded, but what remains of scales seems to indicate 
that they are more dense and more closely adherent to the surface. 
I do not feel justified in considering it specifically distinct until in- 
creased and better material shall prove it to be so. 
A. moleciiliis Casey.— Closely allied to robustulus, with which it agrees in 
form and vestiture, and from which it differs in the following characters: Beak 
shorter and relatively more robust; antennse entirely testaceous, except the 
club, which is darker ; second and third joints of funicle not elongate, equal, and 
together shorter than the following three joints; the head is more densely scaly, 
frontal fovea not well defined, elongate. Prothorax less closely punctured, punc- 
tures smaller; hind angles somewhat depressed; the femoral tooth is extremely 
small. Legs pitchy-black : tibise scarcely widened towards the tip and like the

ung-ularis Group. 
The three species constituting this group are readily distinguished 
by the 6-jointed funicle and the claws armed with a short, incon- 
spicuous tooth ; they are elongate in form ; the elytra have a trans- 
verse denuded fascia. 
They are easily distinguished as follows : 
Beak long and slender, thighs toothed, pubescent. 
Larger, femora feebly clavate, pubescence yellow uiigiilaris. 
Smaller, femora strongly clavate, pubescence white Iloralis. 
Beak short and stout, thighs not toothed, squamous iiubilus.

than the prothorax ; sides nearly straight for two-thirds their length, thence 
gradually rounded to apex; strife fine, superficial, except the sutural one, which 
is more deeply impressed; punctures moderate, elongate, not very close; inter- 
spaces nearly flat, smooth, remotely punctulate; scutel densely pubescent; trans-

from the buccal opening; scape of antennse longer, second joint of funicle a 
little longer than the third. Eyes and head as in ungulnris, front with a few

surface coarsely, but not densely punctured, pubescence more concentrated along 
the inedian line and on the sides. Elytra one-third wider at base than the pro- 
thorax ; strise wider, more deeply impressed : punctures larger, rounded ; inter- 
spaces slightly convex, rugose; under surface as in ungularis. Legs stouter, 
femora more strongly clavate, all toothed; tibise shorter and stouter; the tarsi 
are broader and shorter, and the claws armed with a somewhat longer and acute 
tooth, than in that species. Long. 2. — 2.5 mm ; .08— .10 inch. 
Hab. — Florida, North Carolina. Coll. E. A. Schwarz and H. 
Ulke. 
A specimen in Mr. Ulke's collection, from North Carolina, is 
larger (2.5 mm.) than the average, more coarsely sculptured and of 
a pitchy black color with the pubescence very conspicuous ; it does 
not api)ear to be distinct. 
.4. iiiibilus Lee. — Elongate elliptic, ferruginous to rufo-piceous and clothed

few hairs; front flattened, fovea variable, an obscure transverse impression above 
the eyes. Prothorax wider than long, moderately narrowed anteriorly, sides 
broadly rounded, scarcely constricted at the apex ; surface coarsely, but not very 
closely punctured. Elytra wider at base than the prothorax, sides feebly rounded, 
gradually narrowed to and conjointly rounded at the tip; strife wide, moder- 
ately impressed : punctures coarse, interspaces convex, rugulose; a broad, oblique 
stripe and declivity more densely scaly, suture darker; underside moderately 
punctured, thorax densely. Abdomen sparsely pubescent; last ventral segment

feebly clavate., not toothed ; tibia? a trifle wideoed toward the apex, each tarsal 
joint with a few, white hairs arising near the apical extremity, claws armed with 
a very small, almost imperceptible tooth. Long. 1.8--2.2 mm. ; .07 — .09 inch. 
Hab. — Florida, North Carolina. 
The following variety deserves special mention : Larger and 
darker; frontal fovea sulciform, deeply impressed; the scaly vesti- 
ture more conspicuous; scutelluni, scutellar and intra-humeral spots 
very densely scaly. Long. 2.7 mm. ; .11 inch. Occurs in District 
of Columbia, Florida, Texas, Pennsylvania. 
Subgenus Cnemocyllus. 
Under this subgeneric name I have included all those species 
which have the posterior tibiae dissimilar in the two sexes, those of 
the male being more or less curved, while in the female they are 
straight, or nearly so. This curvature varies greatly, being most 
marked in ornatuhis and figuratus, and least in Ugatus. The fifth 
ventral segment is more or less elongate, except in sabvittatus, or- 
aatulus and figuratus, and very long in inermis. The tarsi are never 
.short and broad, but are very long and slender in a few species. 
The tooth of claw varies considerably in development. The form 
varies from oval to elongate, and the integument is clothed with 
scales, which, in most of the species, form lines or vittae after a com- 
mon pattern, as follows: A pale line on the fourth interspace com- 
mencing about the middle and variable in extent, another vitta on 
the sixth interspace commencing at the base and extending to about 
the middle ; in addition to these there is in some a darker patch or 
fascia on the sides behind the middle. The prothorax is generally 
vittate; the funicle of the antennae is either 6- or 7-jointed. 
The s]3ecies occur in the Western and Southern States, are closely 
related, and require great care to be distinguished. The following 
table, supplemented by the descriptions and figures given, will, how- 
ever, enable the student to positively identify them.

A. ornatulus n. sp. Plate vi, figs. 20, 20a, 206.— Elongate subovate, pice- 
ous, antenuffi aud legs reddish, densely clothed with broadly oval scales, white 
and brown on the upper surface and entirely white beneath. Beak rather 
long and slender, regularly curved and somewhat shining, punctured and sub-

A female specimen in Dr. Horn's and a male specimen in ray 
collection. A very distinct species, not unlike dark colored speci- 
mens of jmuperculus, from which, however, it is distinguished aside 
from structural differences by its bright ornamentation, more trans- 
verse thorax, elongate second joint of funicle, very long tarsi and 
short tooth of claw. For differentiation from figuratus the student 
is referred to that species. 
A. fig^uratiis n. sp. Plate vi, figs. 21, 2\a. — Very similar in form, color and 
vestiture to the preceding, but a little larger, aud the scales less closely applied 
to the derm, and therefore more easily removable; the beak a little longer and 
more robust at the base, with the sculpture more pronounced ; the eyes are placed 
more laterally ; the prothorax but little wider than long, with the punctures 
smaller and more crowded ; the elytral striae., denuded of the scaly vestiture, are 
fine, but well impressed, becoming wider and deeper near the base ; the punctures 
small and closely apjiroximate ; interspaces nearly flat, except at the base, punc- 
tured and somewhat rugose; tiie coloration is almost identical, but less sharply 
defined, the broad white stripe dissolved into two vittae. Legs a little darker, 
thighs infuscate about the middle; tibiae longer, anterior more bisinuate inter-

clothed above and beneath with large, broadly oval, white, or grayish white 
scales. Beak moderately long and slender, curved and scarcely pubescent; three 
elevated lines from base to middle, with corresponding striae between ; scaly at 
the base. Antennre rather stout, second joint of funicle not longer than the 
third; club dusky. Eyes feebly convex, posterior margin slightly free. Head 
punctured and densely scaly, frontal fovea elongate. Prothorax longer than

and closely approximate; interspaces slightly convex. Legs and tarsi slender, 
femora feebly clavate, anterior with a small, scarcely perceptible tooth ; tibiae 
slender, posterior of male feebly curved, fifth ventral segment of male almost as 
long as the two preceding segments united. Long. 2.2—2.5 mm. ; .09 — .10 inch. 
Hah. — California. 
I am not at all certain about the identity of this species, as Le- 
Conte describes the thighs as being unarmed. I have only four 
specimens before me, in all of which the tooth of the anterior pair 
is discernible, but it is quite possible that, on account of its small 
size, it had been overlooked by that author. Two specimens in Dr. 
Horn's collection have the upper surface somewhat mottled with 
brownish scales. 
A. jacobiiius n. sp. — Oblong-elliptic, piceous, antennae, and legs ferrugin- 
ous, densely clothed above and beneath with moderately large, whitish scales. 
Beak not very slender, feebly but regularly curved, opaque (%), or somewhat 
shining (9), indistinctly carinate and striate; scrobes straight. Antenufe 
slender, inserted two-fifths ( ^ ) or one-half { 9 ) from the apex, funicle 6-joiuted, 
first joint not very robust, elongate; second joint longer than the third. Eyes 
feebly convex, scarcely free behind. Head wide, and like the beak at base, 
densely scaly, irregularly punctulate ; frontal fovea small, punctiform. Pro- 
thorax a trifle wider than long, moderately narrowed in front, but scarcely con- 
stricted at the apex, sides nearly straight behind the middle, feebly emarginate 
each side at base ; surface densely and rather coarsely punctured ; scales more 
condensed along the middle and on the sides. Elytra a little wider at the base 
than the prothorax ; sides nearly parallel for one-half their length, thence grad- 
ually rounded to apex, which is moderately dehiscent: striaj wide, impressed, 
punctures large, rounded, and not closely approximate; interspaces convex, 
rugulose; scales a little more condensed on the basal third of the sutural and

Hab. — Colorado. 
A male and female specimen in my collection only very recently 
received. This species resembles cainis very closely in form and 
coloration ; it differs, however, by its greater size, smaller and more 
densely placed scales, the elytra more gradually rounded to the apex, 
the pygidium more freely exposed, and the hind tibite of the male 
strongly curved ; the fifth ventral .segment is longer than the pre- 
ceding in both sexes, especially the female. 
A. <loci|)ieii!ii Lee. — Elongate-oblong, pitchy-brown, antennfe and legs fer- 
ruginous, densely clothed above and beneath with large, oval, grayish white 
scales, which, however, on the abdomen become piliform. Beak long, curved and 
moderately slender, shining, rather coarsely punctured near the base, three ill- 
defined, elevated lines. Antennae somewhat stout, second joint of funicle elon- 
gate, slender and longer than the third, which is a trifle longer than the fourth, 
club dusky. Eyes almost flat, posterior margin slightly free. Head convex, 
punctured and densely squamose; an impressed frontal line extending upon the 
base of the rostrum. Prothorax one-third wider than long, sides feebly rounded, 
subparallel behind, strongly narrowed and distinctly, though not suddenly con- 
stricted at the apex ; surface densely, though not coarsely punctured, indistinctly 
trivittate. Elytra a little wider at the base than the prothorax, oblong-oval, 
almost parallel on the sides, gradually rounded to apex behind, coarsely striato- 
punctate, strife broad and deep, punctures large, oblong and closely approximate ; 
interspaces convex, roughened ; with the scaly covering intact, the latter appear 
wide and flattened, and the stria" and punctures not entirely concealed. Legs 
moderate, femora feebly clavate, anterior feebly toothed ; tibise slender, anterior 
and middle slightly bisinuate internally, posterior of male regularly, but not 
strongly curved ; tarsi slender. Long. 2 — 2.2 mm. ; .08— .09 inch. 
Hab. — Texas, Kansas, Oregon, Washington. 
The pygidium is more or less freely exposed, and the fifth ventral 
segment longer than the fourth in both sexes, though more markedly 
so in the male, while it is foveate in the female. In well-marked 
specimens a posterior pale vitta on the fourth and an anterior one on 
the sixth interspace, as well as a post-scutellar line are more con- 
spicuous ; the darker, lateral space is generally ill-defined. 
A. canus Lee— Closely allied to the preceding species; elliptic, pitchy- 
brown, densely clothed with very large, broadly oval, and uniformly white 
scales: it differs as follows: Beak more slender and shining, more finely sculp- 
tured, slightly widened and somewhat depressed at the apex. Prothorax but 
little wider than long, regularly rounded from base to apex, latter not constricted. 
Elytra more broadly rounded on the sides; striie and punctures still coarser; 
punctures more transverse and very narrowly separate. Legs, especially the

smaller; tbe second and tliird joints of funicle a trifle elongate, equal in length; 
the scales are smaller in size; tibiae more slender, and the posterior of the male

The fifth ventral segment of male is scarcely one-half longer than 
the fourth and of about equal length in the female. The pygidium is 
freely exposed in the male and not at all in the female.

Last ventral segment of female foveate. 
Dr. Horn, who, in this instance also, has kindly made the com- 
parison with the type in the LeConte collection at Cambridge, has 
found the funicle to consist of only six joints and not seven, as erro- 
neously stated by LeConte, and which had led me to doubt the 
identity of the present species with the one described by LeConte. 
This species is very closely related to the following, with which it 
has heretofore been confounded in collections. A specimen from 
Jacksonville, Fla., in Mr. Schwarz's collection, I refer, with some 
doubt, to the present species ; it has the beak a little shorter and 
stouter, the second joint of funicle a little shorter than the third, 
outer joints wider ; the elytra a little wider at the base and not wider 
posteriorly, sides feebly rounded, punctures close set and somewhat 
transverse, interspaces more roughened, and the anterior femora 
more strongly clavate ; it is entirely denuded of scales. 
A. ligattis n. sp. Plate vi, figs. 24, 24a, 246.— Very closely resembles elon- 
gatus in form, sculpture and coloration, and is distinguished from that species by 
the following characters: the second and third joints of the funicle are a little 
more slender and of nearly equal length ; the prothorax more strongly rounded 
at the sides and more narrowed anteriorly. Elytra not wider at the base than 
the prothorax with the sides a little more rounded ; the scales are of a more 
yellowish color instead of the white, and less easily removed, the markings less 
marked ; the dark denuded fascia extends from the sides to about the fourth 
interspace ; the tibiae are more slender and the posterior of the male simply 
emarginate along the internal margin and entirely straight in the female. Long. 
2.4 -2.7 mm. ; .10— .11 inch.

stripe each side of whitish scales. Elytra a little wider at the base than the pro- 
thorax, sides nearly parallel for one-half their length, thence very gradually 
narrowed to the apex ; when viewed from above, a slight subhumeral tubercle 
on the ninth interspace is noticeable; striaj deep, punctures large, not very close, 
and not concealed by the scales, which are predominantly brownish in color; 
scutellum and short scutellar line, base, interru])ted line on the fourth interspace

dle and posterior more slender; tibife moderatel.y stout, nearly straight; tarsi not 
slender, apical half of last joint and claws blackish, latter armed with a long, 
slender tooth, which is closely approximate and parallel with its fellow. Long.

Hab. — Biii'iiett County, Texas. 
A unique female specimen in Mr. Schwarz's collection. Very 
distinct ; differs from the two preceding species, to which it is most 
closely related, in form, and in the claws being armed with a long, 
slender tooth, in this it agrees with subvittatiis, which it also resem- 
bles in form and markings, but differs by its very small size and the 
second joint of funicle longer than the third. 
Subgenus Anthonomochseta. 
Beak long and rather slender, curved and slightly widened beyond 
the insertion of the antenna?, pubescent; scrobes straight, directed 
against the eye. Antennae slender, inserted about two-fifths from 
the gular opening, funicle 7-jointed. Eyes small, round and feebly 
convex. The front is somewhat flattened, with a round fovea con- 
cealed by pubescence. Prothorax a little wider than long, strongly 
narrowed in front and slightly constricted at the apex, base bisinuate. 
Elytra broadly ovate, a little longer than wide, suddenly and fully 
one-third wider at the base than the prothorax ; humeri callous, 
prominent ; regularly rounded on the sides from base to ti}) ; stride 
broad and deep, punctui'ed ; third and fourth ventral segments

pygidium ex[)osed in the male, concealed in the female. Legs very 
slender, femora scarcely clavate and not toothed ; tibiae very slender, 
straight, apical armature very feebly developed ; tarsi slender, claws

armed with a long tooth, approximate to its fellow ; surface densely 
clothed with long, coarse pubescence, intermixed with stiff, erect 
bristles. 
Aside from the vestiture, so unusual in the present trilie of rhyn- 
chophorous coleoptera, the present subgenus differs from Anthonomus 
proper by its rather small eyes and the feeble, til)ial armature. It 
is represented by a single species. 
A. heterogenus n. sp. — Robust, ovate, ferrugrinous to piceous, auteuuie and 
legs rufous: pubescence ashy gray, concealing the sculpture; the erect bristles 
are arranged in a single row on each elytral interspace and also along the outer 
margin of the tibiae, giving them a fimbriate appearance. Beak ferruginous, 
somewhat shining, punctured and indistinctly striate each side ; first and second 
joints of funicle elongate, robust, latter longer than the third joint; outer joints 
wider; club dusky, long, elliptic, pubescent, and rather loosely articulate. Pro- 
thorax densely and finely punctured, underside punctured ; abdomen less densely 
pubescent than the rest of the surface. Long. 2.2 — 2.7 mm. ; .09 -.11 inch.

ASITHOSfOMOFSIS geu. nov. 
I have established this genus on Anth. mixtus Lee, a pubescent 
species, with 6-jointed funicle and the claws armed with a shoi-t tooth. 
It differs from all others by the flattened abdomen, having the first 
and second segments conspicuously elongate and closely connate, the 
former being longer than the metasternum ; segments H-5 relatively 
short and about equal in length, the pygidium scarcely exposed at 
the tip in the male and entirely concealed in the female ; all the 
tibiae are unguiculate at the apex. 
It is represented by a single species. 
A. mixtus Lee. Plate vii, fig. 26. — Subovate, reddish, or pitchy-brown, and 
rather densely clothed with coarse, variegated pubescence. Beak long, not slen- 
der ; punctured and striate from base to near the apex. Antennte stout, fuscous, 
first joint of funicle rather long and stout, second a little longer than the third, 
outer joints wider. Eyes convex. Head punctured and pubescent, frontal fovea 
deep. Prothorax wider than long, narrowed from the base, sides feebly rounded 
and constricted behind the apical margin ; surface densely and coarsely punc- 
tured. Elytra feebly rounded on the sides and widened to behind the middle, 
rather rapidly narrowed to and conjointly rounded at the tip; about one-third, 
and rather suddenly, wider at the base than the prothorax ; strise and punctures 
coarser towards the base, latter closely approximate; interspaces wide, nearly 
flat, and almost smooth, with a few irregular punctures; humeral and a large 
discal spot behind the middle, rufous; a transverse fascia posteriorly on the dis-

and coarsely pubescent. Legs slender, ferruginous; thighs feebly clavate. infus- 
cate about the middle, all armed with a sharp tooth ; tibise slender, nearly 
straight, all armed with a small hook at the apex ; tarsi moderate, first and second 
joints slightly elongate, equal; third feebly bilobed, lobes small; claws diver- 
gent, armed with a small, acute tooth. Long. 2.5 — 3.2 mm. ; .10 — .13 inch. 
Hah. — Pennsylvania, Texas, Iowa, Missouri. 
The pubescence is easily rubbed off. Two specimens taken early 
in the Spring by Dr. Hamilton, and kindly sent me for examination, 
are entirely deprived of pubescence, probably due to hibernation, 
the occurrence of which must be rare among the members of the 
present tribe. 
PSEITDA5JTH01V0MUS gen. nov. 
Beak rather stout, moderately long and curved; scrol)es oblique, 
directed beneath, rarely icraUegi, validus) against the lower extremity 
of the eye. Antennse not very slender, inserted two-fifths (S ) or 
one-half ( 9 ) fi'om the apex ; scape incrassate at its distal extremity ; 
funicle 6-, rarely (relictus) 5-jointed ; fourth joint (third, relictvs) 
shorter and smaller than either of the preceding or following joints 
(except brunneiis, parvulus) ; club loosely articulate, pubescent. 
Eyes variable. Head subspherical, punctured. Prothorax wider 
than long, bisinuate at base, narrowed in front and constricted at the 
apex. Elytra transversely impressed behind the base ; striae and 
punctures coarse and deep ; scutellum densely pubescent ; proster- 
num short in front of the coxse; mesosternum narrowed behind; 
raetasternum moderately long ; ventral segments nearly equal, fifth 
a little longer than the fourth in the female ; pygidium exposed, 
middle coxse narrowly, posterior not very widely separated. Legs 
slender, femora feebly clavate, all toothed ; tibipe slender, anterior 
and middle unguiculate, posterior mucronate at apex ; tarsi slender, 
claws armed with a long and slender tooth. 
The species are all of a rufo-testaceous or ferruginous color and 
pubescent, both on the ut^per and under surface, without any scales. 
In all, e'K.cept facetiis, the first and second, third and fourth, fifth and 
sixth elytral striae become confluent at the base, the intersj)aces thus 
enclosed do not reach the basal margin, the third interspace becomes 
wider and more prominent at the anterior extremity (except faeetus). 
The species reseiid)le each other very closely, are difficult to dis- 
tinguish, and are, with the exception of cratcegi and incipiens, rep- 
resented by a single, or but a few specimens. 
They are to be distinguished as follows :

This species has heretofore been confounded in collections with 
P. cratcegi, to which, indeed, it bears a close resemblance, but aside

A unique S taken by me sotue years ago. The occurrence of 
5-jointed funicle in the present genus is certainly remarkable. In 
general appearance the species resembles inciplens; the color is darker 
than in any other species. 
JVEO.IIA^TIX gen. nov. 
This new genus is established upon two small species from the 
Atlantic States, diff^ering from Anthonomus in the 5-jointed funicle 
and the broadly ovate, antennal club. 
Beak long, not very slender, |iunctured and striate; scrobes com- 
mencing near the middle and directed against the lower segment of 
the eyes. Antennae slender, scape straight, moderately iucra.ssate at 
its distal end; funicle 5-jointed, first joint long and rol)ust, joints 2- 
5 nearly equal, outer joints a little wider, clava broadly oval, closely 
articulate, basal joint shining. Eyes moderately convex and slightly

A little larger and more robust than the preceding ; prothorax 
more distinctly constricted behind the apical margin, and, like the 
elytra, more coarsely punctured. More material from intermediate

ill the male (except nevadicus) and concealed in the female ; the 
tibise are strongly armed at the apex ; claws simple, divaricate. 
The genus differs from Anthonomus by the simple, divaricate claws. 
The s])ecies are elongate-oval in form and rather convex ; they are 
easily distinguished as follows : 
Funicle of anteniife 7-jointed. 
Pubescent, femora mutic iiiiiniciis. 
Squamous species. 
Thorax trivittate, hind tibiae curved curvipes. 
Thorax univittate, hind tibiae straight soriculus.

Thinly clothed with squainiforni pubescence adsperstis. 
Densely scaly nevadicus. 
E. niiniicus u. sp. — Elongate-oval, black, with dull lustre, very sparsely 
clothed with short whitish pubescence, which is a little coarser and longer on 
the thoracic side pieces. Beak about as long as the head and prothorax, moder-

front with the posterior margin rather free. Head convex, finely alutaceous, 
with a few remote, superficial punctures; frontal fovea large and well impressed. 
Prothorax wider than long, strongly narrowed in front, base bisinuate; sides 
rounded from the base, apex feebly constricted ; surface coarsely, but not closely 
punctured. Elytra oblong, fully one-third and rather suddenly wider at the 
base than the prothorax; sides nearly parallel for more than one-half their 
length, thence gradually rounded to the apex ; strife wide, impressed ; punctures 
moderately large and rather closely approximate; interspaces slightly convex, 
rugulose, each with a row of fine, remote punctures, bearing a fine, short hair; 
underside punctured ; ventral segments short, first and second separately less 
than one-half longer than either of the three following, which are short and 
about equal in length {%)\ pygidium fully exposed, convex, punctured. Legs

A unique male specimen in Mr. Dike's collection is before me. 
It is labeled " A. morulns Lee," to which, indeed, it has the greatest 
resemblance, and from which it can only be distinguished by the 
simple claws. From E. adsperms, which it also resembles in form 
and general appearance, it is distinguished by its larger size, finer 
pubescence and T-jointed funicle.

E. curvipes n. sp. Plate v, fig. 32. — Elougate-oval, black, not deusely, 
elothed with rather large white scales. Beak moderately long and sleuder, 
regularly curved, shining, punctured with an indistinct stria each side. An- 
teuuie slender, dark piceous; scape straight, only moderately thickened at the 
apex : funicle 7-jointed, first joint as long as the three following united, second 
scarcely longer than the third; three outer joints a little longer and wider; 
clava not closely 'articulate. Eyes as in the preceding. Head moderately con- 
vex and rather densely clothed with scales; front sulcate. Prothorax wider than 
long, narrowed in front, broadly rounded on the sides and scarcely constricted 
at the apex; base very feebly biemarginate ; surface densely and coarsely punc- 
tured; scales large, more condensed on the sides and along the median line. 
Elytra about one-fourth wider at the base than the prothorax; humeri rounded,

tially uncovered in the male. Legs rather slender, squamous; femora feebly 
clavate, all armed with an acute tooth, which becomes almost obsolete on the 
hind pair; tibiae slender, anterior and middle feebly curved, slightly biemar-

Distinguished by its simple claws and strongly curved posterior 
tibia? ; the latter character might give rise to its being referred to 
the subgenus Cnemocyllus ; examination of the claws, however, will 
]irevent such a mistake. 
K. soriciilus n. .sp. — Closely allied to the preceding, with which it agrees 
in form and coloration of integument, but is a little larger. It differs as follows : 
With the exception of the head, vittte and scutellura, the upper surface is thinly 
clothed with small, semi-transparent scales, under side densely scaly. Beak 
longer than head and prothorax, slender, finely carinate, carina extending from 
the frontal fovea to about the middle of the beak; first joint of funicle less 
elongate, shorter than the three following joints. Prothorax with a narrow, 
entire median vitta of large white scales: sides underneath densely clothed with 
large white scales, which, however, do not extend upon the upper surface. Elytra 
rather finely striate and punctured : scutellum white, a basal vitta on the sixth 
and a short one about the middle of the fourth interspace of large white scales ; 
the tibife are a trifle more slender, anterior and middle nearly straight, scarcely 
emarginate internally, with the apical hook less prominent; the posterior tiliise 
are straight, and the apical mucro is small. Long. 2.5 mm. ; .10 inch.

one-fourth wider at the base than the prothorax; humeri rounded; sides feebly 
rounded and gradually narrowed to the apex, which almost completely conceals 
the pygidium; striai and punctures nearly concealed by the scales; interspaces, 
with the scales intact, flattened ; first interspace gradually widened from base

Five specimens in Dr. Horn's collection. 
The simple claws, 6-jointe(l funicle and dense scaly vestiture, 
readily distinguish this species, which, however, differs in several 
]>oints from the other members of this genus ; the claws, though 
simple, are less slender and less divergent, the lobes of the third tarsal 
joint strikingly narrow, a character 1 have not observed in any other 
Anthonomid ; the almost concealed pygidium, and lastly the dense, 
imbricate, scaly vestiture, present a group which might be considered 
to possess more than specific value. I prefer, however, to leave it in 
the present genus, rather than to establish a new one on what appears 
to me insufficient characters.

The simple claws, covered pygidiuiu and short third and fourth ven- 
tral segments, may be considei"ed valid reasons for placing it near 
Erirrhinus. The formation of the antennre and the general habitus 
are distinctly Anthonomid. It forms a transition from the present

extent, but never invades the first interspace. In some specimens a 
less pronounced darker space near the base. 
E. Scanicus Payk. Plate vii, figs. 35, 35a. — More robust than bipunctntns ; 
ferruginous, clothed with grayish white or brownish pubescence. Beak stout, 
punctured, shining, pubescent at base; second and third joints of funicle equal. 
Eyes as in the preceding. Head punctured, thinly pube.scent, except between 
the eyes. Prothorax strongly rounded on the sides, rather suddenly narrowed 
iu front and narrowly constricted at the apex; base scarcely emarginate each 
side; surface finely and not densely punctured, dorsal elevated line almost en- 
tire. Elytra oval, al)out one-third wider at the base than the prothorax ; striae 
moderately fine; punctures moderate, approximate ; interspaces nearly flat; an 
irregular, oblique fascia about the middle, extending from the second interspace 
to the sides of the elytra; third, fourth and sixth interspaces for a short distance 
near the base and asubapical spot, almost denude of pubescence and only thinly 
covered with fine, brownish pubescence Legs moderately robust; femora cla- 
vate, mutic; tibiae rather stout and but slightly widened towards the tip; tarsi 
very robust, first and second joints much wider than long, fourth joint stout and

rather short, projecting but little beyond the lobes of the third joint; claws 
slender, with a very large, broadly triangular appendiculum at its base. Long. 
2.7—3.3 mm. ; .21— .13 inch. 
Hnb. — Pennsylvania. 
One male and two female specimens. Coll. Dr. Horn and mine. 
I captured my specimen {%) some years ago on oak, and has served 
as the type of the above description. One of Dr. Horn's specimens 
agrees in all particulars (except sexual differences) with mine, while 
the other has the denuded fascia of less extent and the interspaces 
not denuded near the base. 
I have made careful comparison with well authenticated specimens 
of this species from Europe, and can discover no difference, except 
that a small denuded spot each side of the thorax is wanting in our 
specimens, but as this also occurs in one of my European specimens, 
it is probably of but subordinate value. 
E. epliippiattis Say. Plate vii, figs 35c, 35d.— Elongate, ferruginous, 
mottled with pale yellowish and fawn-colored pubescence. Beak punctured. 
Prothorax rather finely and not densely punctured. Elytral strise with large, 
closely placed punctures ; a large scutellar spot and another somewhat rhomboidal 
space behind the middle connected along the suture, of darker color. A trans- 
verse fascia of grayish pubescence immediately behind the posterior dark space; 
underside punctured ; the claws are slender and armed beneath with a large 
rectangular tooth at the base. Long. 2 — 3.3 mm. ; .08 — .13 inch. 
Hab. — Atlantic States; Michigan, Georgia, Kansas, New Mexico, 
Oregon, California. 
A very variable species. The dark elytral spaces are almost ob- 
solete in some specimens. 
Mr. Thos. Casey very kindly has sent me a typical specimen of 
his E. californicus. It is entirely pitchy-black, resembling in this 
respect rather bipunctatus ; legs a trifle paler. The beak is less 
punctured, shining, and the second joint of the funicle is longer than 
the third. In all other respects it agrees with ephippiatiis, from 
which it does not appear specifically distinct, but forms a marked 
variety. 
E. angustatus u. sp. Plate vii, fig. 3.5rf.— Elongate elliptic, ferruginous. 
not very densely clothed with whitish, squamiform pubescence. Beak rather 
slender and moderately long, punctured and somewhat shining; substriate 
and rather densely scaly from base to about the middle. Antennje slender; 
first joint of funicle long and slender, second a little longer than the third, 
outer joints imt little wider. Eyes as usual. Head punctured, occiput sparsely 
pubescent, densely squamous between the eyes. Prothorax wider than long, 
broadly rounded on the sides and very little wider at base than at the apex.

which is not constricted, smooth dorsal line short, just in front of the middle; 
punctures rather small and close set. Elytra elongate, about one-fourth wider 
at the base than the prothorax ; sides nearly straight for three-fifths their length, 
thence gradually narrowed to apex, which is subacuminate ; striae moderately 
impressed, punctures small, closely approximate; interspaces nrarly flat; pu- 
bescence nearly equally distributed ; underside finely punctured and pubescent. 
Legs rather slender, thighs feebly clavate, anterior armed with a small acute 
tooth, which is represented on the middle and hind pair by an acute angle, less 
marked on the hind femur; tarsi less robust, fourth joint extending considerably 
beyond the third ; claws armed beneath with a short obtuse tooth. Long. 2.8-- 
3 mm.; .11— .12 inch. 
Hah. — Arizona, Kentucky. 
Two specimens, male and female, in Dr. Horn's collection. A 
very distinct species and unmistakal)le members of the present genus. 
The rather slender beak and toothed femora are anomalous. 
ORCHEXTES 111. 
The eyes closely approximate above and the saltatorial posterior 
femora make the recognition of the species of this genus an easy 
matter. The beak, variable in length and thickness, lies between 
the anterior legs during repose ; the scrobes commencing about the 
middle or even near the base ; scape of antenna? not long ; funicle 
6- or 7-jointed. The prothorax is relatively small. The elytra oval 
or elongate-oval, wider than the prothorax, with the humeri rounded. 
In reviewing the species I shall give only sufficient descriptive 
matter which, in connection with the synoptic table, will enable the 
student to identify his material. To the species heretofore known I 
have to add one new species. 
They may be tabulated as follows : 
Funicle of antennae 7-jointed. 
Elytra with patterns of pale pubescence. 
An anterior and posterior transverse band, always conspicuous. 
Anterior fascia wide, legs partly rufous epliippiattlS. 
Anterior fascia narrower; legs entirely black salicis. 
A faint subbasal, transverse band only iiiger. 
Elytra unicolorous, black. 
Hind angles of prothorax rounded or rectangular, elytra without lateral 
spine parvicollis. 
Hind angles of prothorax acute; elytra with a subhumeral spine. 
arinatus. 
Funicle 6-jointed. 
Hind femora strongly thickened. 
Pubescence long and coarse, brownish puberuliis. 
Pubescence fine, sparse and whitish. 
Black, thoracic punctures large, irregular; elytral interspaces coarsely 
rugose canus. 
NORTH AMERICAN COLEOPTERA. 267 
Black, thoracic punctures moderate, round ; elytral intersi)aces almost 
smooth, shiuiug paliicoriiis. 
Black, elytra and abdomen red betilleti. 
Hind femora scarcely thickened. 
Legs rufous rnfipes. 
Legs piceous Var. iniiiutus. 
O. epiiippiatus Say. — Robust, oval, piceous ; b6ak, antennaj and legs ru- 
fous. Prothorax small, rufo-piceous, not densely clothed with whitish pubes- 
cence. Elytra oval, much wider than the prothorax ; anterior two-fifths and a 
transverse post-median fascia rufous, or rufo-piceous and densely clothed with 
white pubescence and connected by a line on the second interspace ; femora, 
especially the posterior, wholly or in part piceous. Long. 2.5 — 3 mm.; .10 — .12 
inch. 
Hab. — Pennsylvania, Iowa, Illinois, California, Wisconsin. 
Allied to 0. rufitarsis Genu, of Europe. 
O. saliciK Linn. — Similar to the preceding, but smaller and less robust 
Black, antennae and tarsi rufous; anterior elytral fascia narrower than in ephip- 
piatus, about one-third from the base, irregular, prolonged along the sutural in- 
terspace to the scutellum in front and extended along the second interspace 
posteriorly, but not connected with the posterior transverise band which is nar- 
row and angulated. Long. 2.5 mm. ; .10 inch. 
Hab. — California, Wisconsin. 
This is 0. subhirtus Horn. Careful comparison of Dr. Horn's 
types with specimens of the European species in my cabinet leave 
no doubt of their identity. 
O. iiiger Horn. — Eather robust, subovate ; black, antennae piceous, clothed 
with short pubescence, which is black on the upper and whitish on the under 
surface; scutellum densely white pubescent; an inconspicuous, transverse fascia 
about one-third from the base and consisting of sparse white pubescence. Long. 
2.8 mm. ; .11 inch. 
Hab. — Illinois, Michigan, Pennsylvania. 
The white scutellum i.s in striking contrast with the rest of the 
surftice. 
O. pai'vicollis Lee. — Entirely black, oblong-oval with scarcely any lustre. 
Prothorax coarsely and rather densely punctured ; hind angles subrectangular, 
somewhat rounded. Elytral interspaces very rough. Long. 2.8 — 3 mm.; .11 — 
12 inch. 
Hub. — California, Nevada, Colorado. 
Distinguished from the three preceding species by the absence of 
elytral markings and from the following by its coarse sculpture, 
rounded posterior angles of thorax and the ninth elytral intersjjace 
not produced in a spine. 
268 WILLIAM G. DIETZ, M. D. 
O. arniatiis u. sp. Plate vii, fig. 36. — Subovate, robust, very convex, black 
and shilling ; very sparsely clothed with short, pale, suberect pubescence. Beak 
cylindrical, shining, substriate and rather coarsely punctured, especially near the 
tip. Antennjeentirely pale testaceous, very slender ; scape short, funicle 7-jointed, 
first joint long, second and third elongate, subequal, joints 4-7 shorter, rounded : 
clava elongate. Prothorax wider than long, and nearly twice as wide at base 
than at apex, sides oblique, nearly straight, feebly constricted at tip, hind angles 
acute, punctures moderately large and rather remote, each bearing a short 
whitish hair. Elytra broadly oval, very convex, not much wider at base than 
the prothorax ; humeri prominent, callous and rounded ; strise rather fine, punc- 
tures small and not closely approximate; interspaces slightly convex, smooth 
and shining, each with a row of fine, remote punctures bearing a short, hair: 
the ninth interspace near the base is produced in the form of a short, acute spine 
directed forward : under surface a little more densely and coarsely pubescent ; 
hind femora scarcely incrassate ; tarsi pale rufous. Long. 2.3 mm. ; .09 inch. 
Hab. — Allegheny, Pa. A single female specimen. Collected and 
kindly given me by Dr. Hamilton. 
Very different from any other Orchestes known to me and re- 
markable for its very convex form, shining surface, acute posterior 
thoracic angle, and the acute spine of the ninth interspace. 
O. piiberuliis Boh. — Elongate oval, black, antennse and legs testaceous, 
densely clothed with long, coarse, gray or yellowish gray pubescence; funicle 6- 
jointed; scutellum clothed with white pubescence. Elytra regularly oval, hu- 
meri rounded, not at all prominent. Long. 3.2—4 mm. ; .12 — .16 inch. 
Hab. — California. 
Easily known by its coai'se, yellowish pubescence. 
O. canus Horn.— Similar in form to the preceding species, but the humeri 
are more prominent. Black, autennte rufo-piceous; pubescence short, sparse, 
whitish. Prothorax punctured, punctures rather crowded and irregular. Elytral 
interspaces rugulose, roughened with some lustre. Long. 2.8 — 3.2 mm. ; .11 — .13 
inch. 
Hab. — Michigan, Colorado. 
Resembles 0. stigma Germ, of Europe, but the pubescence is white 
or yellowish, and the elytral strise are less deeply impressed. 
O. pallicoriiis Say.— Similar to canus, but a trifle smaller, with the humeri 
still more prominent. Black, antennae and tarsi reddish. Prothorax less densely 
punctured, punctures less irregular; the elytral interspaces are nearly smooth 
and more shining. Long 3 mm. ; .12 inch. 
Hab. — Atlantic States to Texas, Michigan. 
O. betulef i Horn. — Somewhat elongate-oval ; black, elytra and abdomen 
i)right red ; pubescence sparse, almost imperceptible. Prothorax coarsely and 
remotely punctured. Long. 2.8 mm. : .11 inch. 
Hab. — Maryhtnd, District of Columbia. 
Easily recognized by its striking coloration. 
NORTH AMERICAN COLEOPTERA. 269 
O. rtifipes Lee. — Elliptic, smaller and less robust than any of the preceding 
species. Black, thinly pubescent; anteunse and legs rufous; hiud femora feebly 
iucrassate, more or less piceous. Long. 2 mm. ; .08 inch. 
Closely allied to the European 0. foliorimi Miiller, from which it 
appears to differ by the prothoi-ax being a little more transverse and 
not rounded in front. 
0. minutus Horn is a variety of the above with the legs entirely 
piceous. It occurs in California and Colorado. 
XAIVTHUS gen. nov. 
I have established this new genus ujDon two very small, testaceous 
and thinly pubescent species having the claws simple, divergent, and 
the tibiee almost truncate at the tip, with the armature very small. 
Beak long, rather slender and nearly straight, a little widened to- 
wards the tip, not striate ; scrobes straight, attaining the eyes, which 
are convex. Antenuse moderately stout, inserted two-fifths ( S ) or 
one-half ( 9 ) from the apex ; scape slender, impinging against the 
eye ; funicle 7-jointed, first joint stout, second and third nearly equal,

front sulcate. Prothorax wider than long, feebly narrowed in front 
and slightly constricted behind the anterior margin. Elytra a little 
wider at the base than the prothorax, striate and punctured ; me- 
sosternum moderately wide between the coxse, declivous in front : 
first and second ventral segments moderately long, third and fourth 
shorter, equal ; fifth not longer than the fourth in the male ; py-

■scarcely perceptible. 
ACAL,YFTUS Sch. 
Beak moderately slender, cylindrical, curved; scrobes commencing 
near the middle of the beak, straight, and directed against the mid- 
die of the eyes. Antennae slender; scape incrassate towards its distal 
end, funicle 7-jointed, equally pubescent, without verticels of stiff 
hairs; first joint long and robust, joints 2-7 gradually wider, closely 
articulate, and scarcely longer than the clava, which is ovoidal acu-

one-half the length, following joints short. Head broadly conical. 
Eyes feebly convex. Prothorax wider than long, narrowed in front 
and constricted at the apex; base obliquely truncate each side. 
Elytra wider at base than the prothorax, oval, sides feebly rounded, 
indistinctly striate and punctured, rather suddenly narrowed and 
separately rounded at the apex, leaving the pygidium freely exposed; 
anterior coxie narrowly sej)arated by the prosternum, which is long 
in front of the coxse ; middle coxiie separated by the mesosternum, 
which is declivous in front; metasternum moderately long; first and 
second ventral segments of equal length behind the coxa, third and 
fourth segments short, united as long as the second, fifth scarcely 
longer than the fourth in the male; longer and broadly rounded in 
the female. Legs rather slender, thighs clavate, mutic ; tibiae slender, 
scarcely widened to apex, anterior and middle not unguiculate, pos-

terior with a very short inucro at apex ; tarsi moderately long, first 
and second joints about as wide as long, third deeply, but not broadly 
bilobed, fourth joint slender, moderately long; claws slender, simple 
and divergent. 
An aberrant member of the present tribe; the prosternum long 
in front of the coxse, equally pubescent antennal funicle and un- 
armed tibire are not found in any other. In the long prosternum it 
is somewhat approached by Anth. rufipes. 
The only species occurring in our fauna has been introduced from 
Europe. 
A. carpiiii Herbert. Plate vii, fig. 38. — Oval, piceous, finely and densely 
punctured, and densely clothed above with short, grayish white pubescence, 
having a somewhat silvery lustre; the beak is densely punctured and opaque 
( ■^ ), or less densely punctured, shining ( 9 ) : underside less densely pubescent.

272 WILLIAM G. DIETZ, M. D. 
The type of this genus is a small testaceous insect without close 
relationship in any direction, except, perhaps, Acalyptus, with which 
it agrees in the somewhat flattened thorax, unarmed tibiae and the 
formation of the funicle. It agrees with Alycodes and EUeschus in 
the abdominal formation and appeudiculate claws, but the fifth ven- 
tral segment is very long, and it is very diflferent in other respects. 
E. testaceiis n. sp. Plate vii, figs. 39, 39rt, 396, 39c.— Elliptic, testaceous, 
almost glabrous. Beak shining, with a few remote punctures. Prothorax rather 
closely and finely punctured, with an ill-defined, smooth dorsal line extending 
from the anterior margin to about the middle. Elytral striae impressed, punc- 
tures moderate, close set; interspaces scarcely convex, slightly roughened ; under 
surface remotely punctulate. Long, nearly 2 mm. ; .07 inch. 
Haft.— Buffalo, N. Y. 
A unique 9 in '^y collection. Easily recognized by its pale color, 
ventral formation, unarmed tibite and api)endiculate claws. In ap- 
pearance it resembles Notolomus basulls, without, however, the dark 
basal spot of the elytra.
