The black markings of the elytra and thorax are heavier in eastern than in western specimens and two names may be necessary if we distinguish geographic races. A specimen from Manitoba (figured in plate) in Professor Wickham's collection is conspicuously pale. For the pres- ent I believe it will be preferred to use the original name of the species for all its forms. 3034. A. seriata J/<7.f. , 1846. Maritime regions of Atlantic States and southern California. Ovate, black ; tibice, antenna:, sides of abdomen reddish-yellow ; thorax and elytra reddish-yellow, jiunctulate ; thorax with two large obtriangular spots connected at median line ; elytra each with five spots and a common scutellar spot black. Re- sembles Megilla iitaculata but may easily" be known by the entirely black head and the confluence of the spots. Specimens from southern California are redder and have the elytral spots barely connected. Length, 4.5 to 6.5 mm. ^^ .iS to .26 inch. This species was made the type of N^ceinia by Mulsant and in this he is followed by Major Casey but in view of the feeble characters used I prefer to retain the arrangement of the check list. The name litigiosa Muls., might be revived for the southern California form if it were desired to distinguish the geographic races of this species. 3035. A. episcopalis Kirby, 1837. Canada, Kansas, Wyoming, Colorado (April to June in sweepings, Wickham), Lake Tahoe, California (Fall). Elongate, parallel, bright yellow, body black ; head black behind and with two black vittK ; thorax rounded behind, sinuate before the posterior angles, rather finely punctate with a large three-lobed mark on either side the median line; elytra more strongly punctate, suture narrowly black and a discoidal vitta more broadly black (neither of them reaching the apex). Length, 3.75 mm. = .15 inch. This species has not the characters by which Mulsant sought to separate Nceinia ; if it is to be separated from Anisosticta \\. should be 38 Journal New York Entomological Society.

Canada, United States and southward, except Pacific coast. Ovate, black, alutaceous, thorax and elytra reddish, spotted with black, punctu- late ; head black with a triangular frontal red spot ; thorax with an obtriangular black spot on either side the median line ; scutellum black, elytra with two common spots (one scutellar, one at three fourths) and four arranged longitudinally, one on the callus, one medial larger, one at three fourths and one subapical. The spots become reduced in the \ axitty Jloridana. Length, 4 to 7 mm. = .20 to .28 inch. This species hibernates gregariously. This species may be divided into geographic races and if this be done our common form will be known as fuscilabris. Major Casey has described a large form from Brownsville, Tex., under the name strenua and there is still a third form occurring in Florida and Louisi- ana which is separated already in many collections and may be called ftoridana. These varieties may be separated as follows : Larger form with fully developed markings. Prothorax less than twice as wide as long ; 4.7 to 6.2 mm fuscilabris. Prothorax twice as wide as long ; 5.2 to 7.2 mm strenua. Small form with feebly developed markings ; 4.5 to 5 mm floridana. /Vlegilla floridana, var. nov. Head black, with a triangular red mark ; thorax red, with two small basal black marks ; elytra red, with a common scutellar black spot and each with humeral, an- temedian, two postmedian and apical black spots. The spots are small and separated by more than their own diameter. The inner of the two postmedian spots is not sutural nor is it usually coalescent with the corresponding spot of the other elytron as in the wzrieiy fiisdlabris. Length 4.5-5 mm. Habitat : Florida and Louisiana (Vowell's Mill). I regard this as a well-marked race of maculata. Paranaemia Casey. This genus differs from the preceding by the forms of the tarsal claws, as shown in figure, and by the pattern of maculation. I think it should be recognized. 3037. P. vittigera Mann., 1843. Col., N. Mex., Ariz., Cal., on herbage in swampy places. Ovate, black, alutaceous ; thorax as in the preceding ; pale spot of the head small or lacking in female ; elytra with suture and a dorsal vitta black, both are attenuate towards the apex, which they do not reach. Length, 5 to 5.5 mm. = .20 to .22 inch. March, 1903.] I.ENG : NORTH AMERICAN COCCINELLIU.E. 39 Major Casey has separated under the name sii/ii/is specimens from Colorado and Arizona in which the form is more elongate, the thorax especially so and more rounded at base. I can trace the differences described in the large series I have examined, but do not believe they indicate more than a feebly defined race. Ceratomegilla Crofcli. 3038. C. L'Ikei Cr., 1873. Hudson's Bay. "Oval, sub-opaque, antennre, tarsi and palpi ochreous ; head with a white spot in front of each eye, thorax with the sides bordered with ochreous, anterior angles broadly ochreous, and a very minute line in the middle of the anterior margin also ochreous ; elytra rather closely punctate, a triangular spot on the base, the external margin irregularly, and an elongate common sutural spot near the apex fulvous. L. 22 inch (5.5 mm.)." The claws are dentate at base and the antennre have the third joint longer than the second, broadly dilated at apex, with the inner angle ciliate. Unknown to Major Casey and not represented in any of the col- lections I have seen. I repeat the description of Crotch (Trans. Am. Ent. Soc, IV, 365). Adonia Mu/s. 3039. A. constellata Z(7/]ack, tibiae, antennae and entire front of the head pale ; thorax with a narrow border, an abbreviated medial line connected with the anterior margin and a round dot on either side white ; elytra clearly and rather coarsely punctate, with a scutellar spot and six others (as in Hippodainia') variously united or absent. L. 19 inch ^4.7 mm." This is a European insect and the name is cited as a synonym of variegata Goeze in the Gemminger & Harold Catalogue, and in the later Henshaw list. It is not represented in any of the collections I have seen. I quote Crotch's description. I think this species should be omitted from our list. Eriopsis Muls. 3040. E. COnnexa Germ, Texas, California, Vancouver. Oblong, black, extremely finely and obsoletely, head more visibly, punctate ; thorax with the sides, and a spot on the front and hind margins yellow ; elytra with the margin, base and two dorsal spots yellow ; the marginal line is dilated in five places, one basal, one subhumeral, one medial, one at three fourths and one sub- apical. L. 122 inch =5.5 mm. This is a South American insect, which has very seldom been found in the United States, even if the records are authentic. 40 Journal New York Entomological Society. [Voi. xl I think this species should be omitted from our list. This genus and the preceding are very close to Hippo da mi a. Hippodamia Mills. The synopsis by Crotch includes only part of the now known species ; the later synopsis by. Casey omits several of the previously described species ; I am therefore compelled to offer a new synopsis. Our species fall into three groups distinguished by the character of the sternal plates or more readily by the markings of the thorax, viz : Thorax with broad white lateral margins within each of which is a black dot. The black dot is sometimes connected with the interior black portion, the latter being without the discal divergent lines Group I Thorax with a white quadrate spot at the middle of the base and white lateral and anterior margins variously interrupted Group 2 Thorax with a white lateral margin often interrupted at middle or reduced to an an- terior marginal spot. In this group occur all the species with discal divergent lines on the thorax, but some species are without them (houp 3 Group I consists of one species, ij-pnuctaia. Group 2 consists of one species parenthesis. Group 3 consists of several species separ- able as follows : Anterior half of elytra without markings or with only a humeral black dot...glacialis Elytra with a black subbasal band often reaciiing the humeri, with or without other marks 5=signata Elytra with a common black scutellar spot in the form of a trilobed star, with or without other marks Lecontei Elytra black with a subapical red spot moesta Elytra immaculate ambigua Elytra with six small spots, seldom even partly confluent COnvergenS Elytra with sutural margin wholly or partly black and each with four spots distinct or united or with a sinuous vitta formed by the union of the spots sinuata Elytra with a broad subbasal band and a large medial spot dispar 3041. H. 5==signata Kirby, 1837. Extends from New York ( Adirondacks) to California, following a northern range but descending also to Colorado, Utah and New Mexico in the mountains. In the most heavily marked form the thorax is all black except the anterior angles, and the elytra have three black bands, one subbasal, very broad, disconnected at suture ; one post-mediaii also broad but abbreviated, the third subapical and scarcely more than a good-sized spot. In the palest form the thorax has a white margin and discal lines, the elytra bear no marks behind the subbasal band which is March, 1903.] Lenc : North Amkrican Cocci nellid.i:. 41 much reduced. 'rhis form is confined to the Pacific coast and is exfensa Muls. Between these two extremes occur very many inter- mediate forms, some of which have been named by Major Casey, but in view of the variability of the large series before me collected at vari- ous points in the Rocky Mts. by Mr. E. J. Oslar, I am not sure that these names represent even established geographic races. For cabinet arrangement these forms may be arranged as follows if desired : Three elytral bands 5-signata Subapical band or spot lacking leporina Mii/s. (T'cm/'x Csy. ) Subapical band lacking, middle band represented by two spots unnamed. Subbasal band narrower, others represented by small dots (united in puMCticoIlis Qj'.) subsimilis c\r. Middle and apical band lacking extensa Afn/s. The last occurs as far as I know only west of the Sierra Nevada, is certainly a good variety and should be added to our list as 3041a. H. extensa .l////.f., 1851. Cabfornia. 3042. H. ambigua At-c, 1852. California and Oregon. With this species, itself closely related to the preceding I include as geographic races obliqtia and politissima of Casey. All the forms have immaculate elytra rarely a few small spots but may be separated as follows : Thorax without discal divergent lines ambigua. Thorax with discal divergent lines. Elytra feebly alutaceous obl iqua . Elytra highly polished politissima. The discal divergent lines of the thorax when present may be rep- resented by two short dashes at middle of thorax, or they may be so extended as to leave only a narrow black design on a white ground. In the series collected for me by Miss Dennis at Dilley, Oregon, every intergrade can be found. 3043. H. Lecontei Muh., 1S51. Colorado to California. In this' species the trilobed scutellar spot is accompanied by hu- meral spot, post-median spots or band and subapical spot and its pat- tern of maculation closely resembles that o^ ^-signata. 3043a. H. mcesta Lcc, 1854. British Columbia, Oregon. Very distinct from all others and I know of no reason for regard- ing it as a variety of the preceding. 3044. H. glacialis Fab., 1775. Northeastern America. No division of this species has been proposed. Major Casey is in 42 Journal New York Entomological Society, [Voi. xi. error in saying "anterior spots always wanting." About half the specimens I have seen have a small black humeral dot as well as the post-median band and subapical spot. 3045. H. 15=maculata il////^., 1851. Kansas and Arkansas. I regard as a variety of convergens. 3046. H. convergens Gucr., 1846. North America. The pattern of maculation in this widely distributed species is six spots on each elytron and a scutellar spot. The discal divergent lines are usually well developed. The variations are : Elytra immaculate obsoleta Lee. Anterior and scutellar spots coalescent unnamed. Postmedian spots coalescent juncta Csy. All the spots enlarged and partly coalescent 15=niaculata Muls. 3047. H. spuria Zfc, 1861. Oregon, Vancouver. "This species has the form and size of our coxaxxxon H. parenthesis, hyx\.^c thorax of H. convergens. The elytra are more elongate oval in form than in either, and more obtusely rounded at tip ; the apical angle is also not at all acute, but on the contrary, quite rounded. The spots of the elytra vary greatly ; the scutellar elongate spot is sometimes prolonged on the sutural margin for two thirds the length ; the first and second, or the second and third of the posterior spots are connected sometimes as in varieties of H. parenthesis, and specimens will undoubtedly be found in which all three are united to form an arcuated spot. It is also probable that H. sinuata Muls. is an extreme form of this species. Long. .20. Oregon." I consider this a variety of sinuata to be separated as noted below. It seems as if Major Casey had somehow been misled in regard to this species as his description does not coincide with that of Dr. Le- conte and the locality (Colorado) cited is, in my belief, far from the region inhabited by Leconte's species. Leconte's description is here quoted. 3048. H. oregonensis Cr., 1873. Oregon. Differs from the preceding by the absence of the discal divergent lines on the thorax. I believe that this is a form of sinuata var. spuria, but in the absence of sufficient specimens I am obliged to leave the name in doubt. 3049. H. sinuata .Muls., 185 1. var. spuria Z.v. , 1861.

March, 1903.] LeNG : NORTH AMERICAN COCCINELLID.E. 43 In this species the basis of the markings may be regarded as four spots, one subhumeral, one subsutural near the middle, one submar- ginal behind the middle and one subapical. There is also a sutural stripe, more or less developed. In the true siniiata the spots unite to form a vitta arcuately sinuate posteriorly. Sometimes the union is incomplete, the apical spot be- ing separated {amcricana Cr. ). The sutural stripe is narrow and reaches nearly to the apex. The color is quite reddish. All the specimens I have seen are from New Mexico. In the variety spuria Lee, the subhumeral spot is usually separate and the three posterior spots are wholly or partly united, forming an arcuate spot as in pare/itfiesis. The subhumeral spot, however, may also be united, in which case we have the form called complex by Casey. I include under spuria Lee, also oregoncnsis, differing only by the absence of discal thoracic lines, a character instable in a preceding species. In spuria Lee, the sutural stripe is a short broad mark sur- rounding the scutellum as in parenthesis. The color is paler than in si/iuata. The home of this variety is in Vancouver, Oregon, and Washington, but I have a specimen collected by Mr. Warren Knaus in Kansas, which could be placed here. In the variety trivittafa the vitta of sinuaia is almost reproduced, but I have seen no specimens in which the vitta is broken by the sepa- ration of the apical spot and the sinuation in the vitta is less marked, so that, as Major Casey says, the design is very much like that of Para- ncemia vitfigera. The sutural stripe is usually very long, but it is some- times a short scutellar blotch as in the preceding variety which makes the form called crotclii by Casey. The color is comparatively pale in this variety. Its home is in California. It is probable xSxzX fa Itinera Cr. , differing only by the absence of discal thoracic lines, is to be included here in which cases Crotch's name must be used ; but I have seen no specimens from the locality named by him (Slave Lake, Hudson's Bay) and I prefer to leave this name in doubt for the present. In the variety called spuria in Major Casey's paper (but which is really nameless for, as I read the descriptions, spuria is preoccupied) the four spots are entirely separated, or the two middle spots may be united, or some of the spots may be lacking. The sutural stripe is usually short and narrow. The color is yellow, or reddish-yellow in specimens from New Mexico. I have specimens from Utah, Colo- rado, Kansas, New Mexico, Nevada, Dakota, Idaho and Wyoming 44 Journal New V^okk Entomological Society. [Voi.xi. and a specimen from Vancouver in Professor Wickham's collection has the markings so reduced as to be placed here. It seems to me as if all these forms constituted one species which may have originally had the four spots ; with a tendency to establish the varieties sinuata, trivittata and spuria Lee, in each of which, however, there is a tendency to revert to the ancestral type. 3050.

British America and the northern part of the United States, extending to Colorado in the mountains and from New England to California. There is a great variation in the elytral markings, as will be noted by the figures. The quadrate white spot at the base of the thorax seems to be constant. Major Casey has proposed the name apicalis for that form in which the subapical spot attains the suture and apical angles, but I doubt very much if this indicates an established race. If so, it should be cited as 3051a. Var. apicalis Casey, 1899. Nevada and California. 3052. H. falcigera Crotch, 1873. Slave Lake, Hudson's Bay. " Black, clearly and finely punctulate ; head with a small frontal spot, yellow ; thorax with a narrow uniform border yellow, no discal spots ; elytra yellow with the suture black (narrowing out before the apex) and each with a black equally broad vitta suddenly incurved before the apex ; meta-epimera black. L. .22 inch." This I have not seen, but as stated above, I believe it to be the variety of sinitata called trivittata by Major Casey. The above is a copy of the original description. 3053. H. americana Crotch, 1873. Kansas, Hudson's Bay. Under this name Crotch described sinuata with the apical spot de- tached and I do not think that the name can be anything but a syn- onym unless it be regarded as the first description of a departure from the true sinuata form and hence including all other departures in the same direction. In this view the name could be used for the fourth variety of sinuata, called spuria by Major Casey. 3054. H. variegata Goeze, iTTJ. Should be dropped. See under Adonia constellata above.

I have not seen the type and the figure is drawn from a specimen in my own collection from the same locality and seemingly identical with the insect described by Major Casey. Mr. Blanchard has speci- mens from New Mexico, collected by Prof. F. H. Snow in which the subbasal band and median spot are connected. The elytra in one specimen bear also a disconnected subapical spot. I regard these as a form of dispar. NOTES ON THE CEROSTOMA GROUP OF YPO- NOMEUTID^, WITH DESCRIPTIONS OF NEW NORTH AMERICAN SPECIES. By August Busck. While endeavoring to arrange some American moths of the Ceros- toma group and for that purpose examining critically the European species placed in that genus by modern European authors, I was sur- prised by the diversity of forms included under that generic name. Meyrick, in his Handbook of British I, epidoptera, includes in Ccros- toma all English Yponomeutidce which have veins 6 and 7 in the hindwings stalked. This is at least more consistent than the course pursued by Rebel in the Catalogue of European Lepidotera, where he places one of them, jnucromella Scopoli, under a separate genus Theristis, leaving the rest, which readily separate into four just as distinct genera, in Cerostoma. The natural way seems to be to divide the group into the five genera defined by Wallengren (Ent. Tids- krift, I, p. 53, 1880), but some of his generic names will fall in favor of Hiibner's earlier terms. The genus Cerostoma was founded by Latreille (Hist. Nat. des Crust, et Ins., Vol. Ill, p. 416, 1802) and was characterized as fol- lows : "Ailes tres-alongees, etroites, monies sur le corps. Quatre pal- pes distinctes ; les superieurs droits, les inferieurs long et recourbes ; leur second article penicilliforme, le derniere conique, alonge, presque nu." The type of this genus is Ypsolophiis {Aliicita) dorsatus Fabri- cius, that being the only species mentioned by Latreille both in this volume and in Vol. XIII, p. 247, 1805.
