$ 1. Hippone, on Ammi visnaga, 15, viii, 96. {A. E. E.) 
This specimen apparently differs only from dilatata in 
having the yellow colour more developed, it has the 
mandibles labium and hind tibia3 entirely flavous, and has 
a small black spot on the intermediate tibiae. The form of 
the scape of the antenna3, however, and the sculpture 
throughout appear to me to be identical with those of 
dilatata. In colour it more resembles ccrvicornis, Costa.

These specimens again are slightly different from what 
we know here as sjdlota, and I have had very great doubts 
as to whether I should describe them as a new species or 
not, but I have decided against doing so. Of the three 
males one is stylopized so that its characters may have 
been altered by the effect of the parasite. The others 
differ from the typical form in having the mandibles and 
labrum pale. The female differs from the typical form in 
having the first segment of the abdomen more finely 
punctured, but the characters are not decided enough to 
satisfy me that the two forms are distinct.

All the males in both collections are of the ordinary red- 
bodied type and nearly all the females have the clypeus 
with a white central line, but three females of the var. 
180 Mr. Edward Saunders on 
ahsoluta were found by Mr. Eaton, at Medea on Eryngium 
triqudruvi and two at Constantine on Eryngium triqud- 
rum and Thaiisia garganica ; also among his specimens 
are four females with broad red mesonotal stripes and two 
males with the propodeum posteriorly red ; of these the 
two males and two of the females were taken at Hippune, 
the other two females at Biskra. In these highly-coloured 
females the central polished line of the posterior face of 
the propodeum is more or less red, but the colour does not 
spread over the rest of the surface as in the males.

lateral patch of white pubescence on each side of the base, all the 
segments with a rather broad pale semitransparent apical ring, 2nd and 
3rd ventral segments clothed on the disc with projecting white hairs. 
$ Kesembling that sex of malacJuirus but with the clypeus more 
produced giviug the face a longer shape, and with an almost im- 
perceptible puncturation on the basal segment of the abdomen, the 
surface of this segment under a Coddington lens is seen to be 
exceedingly finely aciculate with a very fine and rather scattered 
puncturation, in malachurus the puncturation is fine and very close. 
The propodeum in the species here described is shorter and wider at 
the apex than in malachurus, and the white patches of hairs at the 
base of the 2nd segment much more developed, the entire abdomen 
also is much less hairy.

Like Bosx r. trimmerana in colour but narrower and in form more 
resembling the 5 of biicephala, and evidently belonging to that group 
by the form of the antennae. I thought at first it was identical with 
macilenta, Perez, but of that species the author says, "abdomen tres 
luisant " whereas in this species it is duller than in rosx. The 2nd 
joint of the flagellum in the male is about equal in length to the 
following 2 together, in the 5 about as long as the following 3. The 
rest of the joints slightly longer than broad in the ^ , distinctly so 
in the 9 ) hairs of tlie face in the ^ brown margined with black, 
in the $ black throughout, thorax clothed with bright brown hairs 
those of the sides jjaler, propodeal area very finely sculptured its 
margins slightly shining, abdomen narrow, not wider than the thorax 
in the $ , nearly dull, finely rugulose with a remote puncturation 
which recalls that of the humilis group ; 1st and 2nd segments 
sparingly clothed with long brown hairs, apices of the segments 
narrowly, discoloured, the 2ud and 3rd in fresh examples with an 
apical fringe of brown hairs ; 4th, 5th, and 6th segments clothed with 
black hairs, hind tibiaj very narrow, scopoe very small. Process of 
8th segment in the ^ rather short and wide, sharply elbowed near 
the base, its apex truncate, and its sides fringed with hairs which are 
shorter towards the apex, armature with its lobes slightly produced 
in front.

Hymcno'pteTa aculeata collected in Algeria, 209 
Andrena minutula, group of. 
This exceedingly difficult section of the genus requires 
a complete revision, and as I have neither the material 
nor opportunity to prepare one I am obliged simply to 
indicate the number of forms contained in the collections 
and where possible to assign them to described species, 
where that is impossible I give the characters which I 
notice as belonging to each. I think when I explain the 
position in which this section now stands I shall not be 
accused of undue cowardice in hesitating to refer the more 
obscure species to any of the descriptions now extant. I 
have spent months over this group and feel sure that no 
satisfactory result can be obtained without having the 
type specimens of all the species under one's eye and 
providing a complete synopsis of them. 
There are over 30 presumed species described, of which 
nearly half are known by one sex onl}' (the % ), in those 
where the ^ is described I can find no allusion to the 
forms of the apical segments and armature. These give 
very reliable though in some cases slender characters, 
and without the help of these I have been unable 
even from the descriptions of celebrated Hymenopte- 
rists to determine my species. The sculpture of the 
clypeus and abdomen appears to me to be more or 
less variable although there seem to be definite types 
of sculpture which keep distinct notwithstanding the 
variations in each. Another difficulty arises as to the 
essential characters of the males. To examine these, 
unless they have been extracted when fresh, means to 
destroy more or less the specimen and to make a proper 
description of its external characters impossible. Mr. 
Morice, who collected a large number of males at Algiers, 
first pointed out to me several forms of armature amongst 
his captures and in dissecting my own taken by Mr. Eaton 
I find others. Of all these I propose to give diagrams as 
I think no description will satisfactorily point out the 
distinguishing characters. I had hoped that the relative 
proportions of joints 1, 2 and 3 of the flagellum might 
have afforded reliable characters, but they are so nearly 
the same in most of the species and appear to vary so in 
accordance with the position from which they are regarded 
that very little satisfactory evidence can be got from 
them.

This ^ is peculiar in Laving the clypeus raised until just above 
the anterior margin, so that the rounded front edge of the elevation 
looks like the apex of the clypeus, it is very shining and remotely 
punctured. Antennje dark testaceous beneath with the 2nd joint of 
the flagellum shorter than the 2 following together, 3rd shorter

in length towards the apex. Face vertex and cheeks clothed 
with white hairs. Thorax clothed with white hairs. Mesonotum 
finely rugulose without evident punctures, propodeal area not clearly 
limited, finely rugulose. Abdomen finely rugulose slightly shining 
without definite puncturation, apical impressions well defined, rather 
narrow, very pale, smooth and less sculptured than the rest of the 
segments ; segments 2, 3, and 4 with white but not very conspicu- 
ous lateral bands of hairs, tarsi except the metatarsi testaceous. In

Andrena beta. 
A slightly larger species than the preceding, face including the 
clypeus densely chjthed with pale ochreous hairs, from what is 
visible of the clypeus between the hairs it appears to be very largely 
and closely punctured. Antenna? pale testaceous beneath, 2nd joint 
of the flagellum unusually short, the 3rd joint very wide and trans- 
verse which makes it look like a continuation of the 2nd, as it is 
quite as wide or possibly wider than that joint, 4th and following 
joints nearly quadrate, the apical joints rather longer. Vertex 
clothed with pale hairs, thorax clothed with pale hairs. Mesono- 
tum finely rngulose and slightly shining with a large scattered 
puncturation, propodeal area rugulose especially near its base ; 
abdomen rather shining, finely rugulose, impressions narrow and 
deep, nearly smooth and much discoloured, sides of the segments 
with inconspicuous bands of whitish hairs ; tarsi of all the legs 
pale.

The face is clothed with pale hairs, the clypeus is finely rugulose, 
punctured and somewhat shining, the antenna? have the 3rd and 4th

clothed with whitish hairs, finely rugulose, without evident punctures, 
propodeum very finely rugulose its area merely indicated by a

Andren^a zeta. 
A species which closely resembles nana of Kirl)y in the punctura- 
tion of the abdomen. I thought at one time it might prove to l)e 
ahstersa, Per., but it has not got an unusually convex abdomen 
neither is the appendix of the labrum unusually small as desciibed

gradually increasing in length towards the apex. Mesonotum finely 
rugulose and with some scattered shallow punctures, propodeum 
finely rugulose its area scarcely determined, abdomen elongate, 
very finely rugulose with an exceedingly fine puncturation scattered 
among the rugulosities of the 2nd and following segments, apices of 
the segments slightly discoloured but scarcely impressed, the sculp- 
21 G Mr. Edward Saunders on 
ture like that of the disc but impunctate, lateral fringes very

very unusual shape of the 8th ventral segment with its somewhat 
bottle-brush arrangement of hairs at the apes, and the very elongate 
armature.

This species is very closely allied to fallax, Hdl., and may prove 
to be only a variety of it. It however differs in the following 
characters which appear to me to be more than varietal. 
In both sexes the head and thorax are clothed with deciduous 
white scale-like pubescence, as well as with short erect pale hairs, 
this deciduous pubescence is more marked in the 5 and the longer 
hairs more so in the ^ . The green colour of the surface is of a less 
bluish tint and in the ^ the surface is duller. The abdomen in the 
^ has the apices of the 1st 2nd and 3rd segments broadly, of the 
4th and 5th narrowly, and the entire 6th and 7th testaceous ; in the 
5 the whole abdomen is very pale testaceous, the 1st 2nd and 3rd 
segments beari ng a narrow slightly curved black line across the disc 
but not reaching either lateral margin, in some specimens the line 
on the 3rd segment is interrupted in the centre ; the width of these 
lines varies considerably, and also their length, in some the line on 
the 3rd segment is absent, and in some there is a line on the 4th, and 
rarely one on the 5th.

Another species of very similar coloration and vestiture to the last ; 
in the two males however which I possess one has a short black

the basal segment only, both sexes may be known from either fallax 
or squamiger by the longer face. This is distinctly longer than 
wide in the (^ , and oval not round in the $ , the face of the 9 much 
resembling that of pulchellus although a trifle wider, the ^ has the

Precedentibus multo major scutello viridi seneo, flavo bimaculato, 
abdomine utroque sexu flavo segmentorum apicibus nigro faaciatis. 
A species of almost twice the bulk of any of the preceding. It 
has a round wide head in both sexes as in the 5 of deceptor and 
is clothed with white deciduous pubescence as in that species and 
squamiger but differs from both of them in its much larger size, and 
in the colour of the scutellum ; this only bears two testaceous spots 
as in the $ of variegatus, and the mesonotum of the $,just in front 
of the scutellum, is testaceous. This also is a character of variegatus 
but the broader face will distinguish it at once from that species in 
the 5 and the pale abdomen with regular dark fasciae in the (^ . 
These fascia? in both sexes are wide and cover the apices of the 
segments, whereas in both squamiger and deceptor the fasciae in the 
224 Mr. Edward Saunders on 
$ run across the disc and in the ^ of these species it is the apical 
portion of the segments which is pale.

especially the 8th 9th and 10th, thorax clothed with very pale 
ochreous hairs above, with white hairs beneath ; mesonotura in- 
cluding the scutellum shining, remotely punctured, wings hyaline, 
nervures piceous, 2nd recurrent received in the 2nd submarginal 
cell, propodeal area depressed dull and finely rugose, bounded 
posteriorly by a shining curved somewhat raised line, abdomen 
strongly and remotely punctured and clothed with scattered pale 
hairs, the segments much raised across the disc, apical impressions 
very deep, pale and impunctate and crossed by a fringe of fine hairs 
which grow on the apex of the raised portion of the segments, legs 
with pale calcaria and clothed with white hairs. 
5 differs from the ^ in the ordinary sexual characters, also in 
being more finely punctured. The antennse are testaceous beneath 
and at the apex, and the joints of the flagellum are very short and 
transverse, vertex of the head and mesonotum rather closely but 
irregularly punctured, in this respect very diff"erent from vulgaris, 
propodeum like that of the ^, puncturation of the abdomen less 
strong than in the (J but well marked, that of the basal segment 
stronger and more remote than of the others, impressions very wide

This is probably a distinct species but from a single ^ I do not 
like to treat it as such. The tubercles and tegulae and scutellar 
spots are ferrugineous not flavous and the hairs of the ventral seg- 
ments are much shorter, the wings are more clouded and the 3rd 
submarginal cell wider. At the same time the general form of the 
insect is so similar to that of tripunctata that I think it safer not to 
describe it as new

(^ . Face clothed with ochreous hairs, antennse with the 2nd and 
3rd joints of the flagellum subequal, its basal joints to the 6th more 
or less infuscate posteriorly, joints 3, 4, 5 of the flagellum distinctly 
and 6 indistinctly tuberculate beneath, all the joints of the flagellum, 
except the small basal one, as long as wide, those nearer the base 
slightly longer. Mesonotum closely and strongly punctured sparingly 
clothed with ochreous hairs, scutellar tubercles slightly raised, pro- 
podeum finely rugose, bearing a patch of silvery hairs on each side, 
legs with the apices of the joints of all the legs and the front legs 
almost entirely, rufo-testaceous, posterior tibiae in the 2 with 2 
short and 1 very long pale spine at the apex. Abdomen shining, 
vaguely and very finely punctured on the basal halves of the seg- 
ments, in the ^ the 'abdomen is brown with paler bands or spots, 
on the 2nd and 3rd segments, these are more or less indicated 
according to the darkness of the specimen.

diminish in size on the more apical joints, whereas in 
eypliognatha, Professor Perez says, "la derniere la plus 
forte." The labrum also is simple.

There seems to have always existed a great deal of 
confusion about Smitli's Bliilo'cmus melectoidcs. This is 
unquestionably identical with Ammobates oraniensis, Lep, 
Smith distinctly says it has two jointed maxillary palpi, 
which fact at once separates it from Phiarus which has 
six joints to those organs. Besides this I have an 
example from Albania named by Smith himself.

Caput et thorax nigra, supra pilis adpressis ochraceis, subtus albis,

Head and thorax black, so densely clothed with closely-fitting 
scale like hairs that the surface can hardly be seen, the clothing of 
the upper surface of the thorax and the vertex of the head is 
ochreous, that of the face and under-side of the thorax and of the 
post-scutellum and the propodeum white, abdomen testaceous -brown, 
basal segment clothed with pale ochreous hairs except a central 
band of bright chocolate-brown hairs which does not reach the 
margin on either side, 2nd segment clothed at the base with bright 
chocolate hairs, at the apes with a wide band of ochreous hairs which 
is considerably and suddenly widened at the sides, 3rd 4th and 
5th almost entirely covered with ochreous hairs, antenrnx! and legs 
testaceous, wings clouded at the apex, nervures testaceous. Labrum 
largely punctured, its anterior margin entire or slightly sinuate* 
two very small tubercles are situated at about a third of the length 
of the ;labrum from its apex. Antennte with the 2nd joint of the 
flagellum longer than the third, the remainder subquadrate, scutel- 
lum with the lateral teeth long, its central lobe emarginate with 
a well-marked angular tooth on each side, the sculpture is 
everywhere hidden by the closeness of the pubescence. 
Long. 7 mm. 
A species closely allied to aureooestitus, Dours, but 
differing so widely in colour, and in the entire bands of 
the abdomen that I think there is no doubt of its being 
distinct.

hsemorrhoa, also the cheeks behind the eyes are clothed with scale- 
like hairs, whereas in hivmorrhoa these hairs are of the ordinary 
type, the transverse impressions of the abdomen are deeper and the 
bands are made up of several rows of scales throughout their extent, 
the entire base of the 7th segment is clothed with white hairs and 
not only its centre — beneath the whole surface is clothed with scales.

(^j$. So closely allied to phceoptera, K., that it will only be 
necessary to point out its differential characters. The head and thorax 
are much more closely punctured so that their surface is quite dull, 
and they are more evenly and closely clothed with grey hairs, the 
abdomen on the other hand in the 9 is less closely though quite as 
largely punctured especially on the 3rd segment. The abdominal 
puncturation in the males of both species is very similar, but the 6th 
segment in the ^ of pha^optera has a stronger apical angle. In both 
sexes of the new species the face is broader and therefore rounder 
and in the 9 the eyes are more convergent.

with a rather narrow apical band of white hairs, apical dorsal valve 
punctured at the base and clothed with golden hairs towards the 
apex which is rounded, 6th segment with an angular tooth on each 
side at the apex, segments beneath shining, punctured, their posterior 
margins rather widely piceous, legs simple, clothed with white hairs. 
5 . Face clothed with white hairs, 1st joint of the flagellum about 
equal in length to the 2 following together, mesonotum clothed with 
rather l:)right brown hairs, thorax beneath and propodeum clothed 
with nearly white ones, abdomen closely punctured, basal segment 
clothed with ochreous hairs on its anterior half, its apical margin 
smooth and shining, 2nd and following segments with a narrow apical 
band of white hairs, that of the 5th golden in the centre, and the 
2nd also with a line of white hairs on each side at the base, apical 
dorsal valve small, finely and transversely rugulose, legs clothed

$ . Very distinct from any other species of the genus by its more 
extensive pattern of snowy-white pubescence — the head, thorax 
except a band across the mesonotum between the tegulse, and the 
greater part of the scutellum, clothed with snowy-white hairs, all 
the segments of the abdomen with a wide apical band of similar 
hairs narrowly interrupted in the middle, the 1st and 2nd segments 
with the sides also white-haired, and the first having its base also white, 
tlie white pubescsnce of the 3rd and following segments almost covers 
the wliole of the exposed surface, legs with the apices of the femora and 
the tibite and tarsi externally clothed with white hairs, labrum 
piceous, antennse very short and stout, piceous anteriorly, the basal 
joint clothed with snowy hairs the 3rd joint almost as long as the 
4th and 5th together the 4th and following transverse, much wider 
than long, each joint posteriorly with a shining round impression, in 
this respect agreeing with crassicornis, Mor., mesonotum coarsely 
punctured, tegulre piceous, with fine very remote punctures, wings 
hyaline, their apices darker, nervures dark piceous, the scutum of 
the mesonotum is posteriorly emarginate, and its angles are produced 
beyond the base of the scutellum so as to be slightly prominent, the 
scutellum is very largely ^^mctured, emarginate posteriorly and 
produced at the sides into two sharp piceous angles, the emargination 
fringed with white hairs projecting from beneath — abdomen slightly 
shining, finely punctured, apical segment bidentate, beneath shining 
the segments each bearing two snowy-white sjjots, tarsi piceous at 
the apex, there appears to be no fringe on the apex of the 6tli 
segment.

(A. E. E.) 
Apparently closely allied to crassicornis, Mor., but there 
is no mention in the description of that species of the 
peculiar form of the mesonotum, and the arrangement of 
the white pattern on its abdomen appears to be quite 
different, each segment having 2 oval spots widely 
separated from the margin, whereas in this species they 
have wide bands.
