Eupsychoma geometrica. n. sp. (Plate 2, fig. 1.) 



Wings and veins dull blackish, latter testaceous when denuded ; a 

 rounded moderate whitish spot on the disc, a longitudinal lower broad 

 whitish band from the base of the wing parallel with internal margin, 

 terminating abruptly after having traversed three-quarters of the length 

 of the wing ; a subtermiual oblique broad similarly colored band nar- 

 rowly divided interiorly by the median nervules. Costa beneath, and 

 costal edge at base, showing scattered yellowish scales ; under surface 

 same as upper, except that the longitudinal band above internal margin 

 is interrupted at base where it is slightly yellowish. 



Posterior wings concolorous, dull black, immaculate; beneath similar, 

 with a super-anal whitish rounded spot. 



Head and palpi clothed with rough blackish hairs, tongue dark tes- 

 taceous ; prothorax black, broadly edged with deep yellow. Legs 

 blackish, streaked with whitish on the tibiae. Abdomen dull black 

 with lateral pale yellowish markings on the segments and at anus. 

 Thorax and teguh'e black, latter clothed with long fine hair which is 

 white on the sides. Exp. 1.50 inch. Length of body .4o inch. 



Habitat.— Colorado Territory. (Coll. Ent. Soc. Philad.) 



The Lepidopterous fauna of Colorado Territory is rich in Zygsenid 

 for in s ; we have Callalucia vermiculata Grote. Eupsychoma geometrica 

 Grrote and Anatolmis Grotei Packard, all structurally very distinct and 

 original genera, while the Territory affords also representatives of our 

 Eastern Zygsenid genera since I have from thence a specimen of Scep- 

 sis fulvicoll 'is Walker, undistinguishable from our specimens from Can- 

 ada and the Eastern States, except that the " collar" is of a paler yel- 

 low, and quite distinct from the Californian species described but not 

 named by Dr. Packard in his paper " Notes on the Family Zygsenidae" 

 p. 43, and which latter may be named Scepsis Packardii. Dr. Pack- 

 ard thus describes the latter species : " The specific distinctions are 

 these ; a light tint of brown, a brownish abdomen, instead of deep blue. 

 and a more hairy thorax than in S. fulvicollis, while in size, the two 

 species are much alike." 



The genus Ctenurha Kirby. is represented in Colorado by C. Oress- 

 onana Grrote, structurally identical with our Eastern C. virginica 

 Charp. sp.. while Alypia Hubner, is represented by A. Ridingsii Grrote. 

 so that I feel confident from information and already collected material 

 that this family will be found extensively represented in Colorado. 



This distribution of Eastern genera among Territorial forms is in- 

 teresting as regards the geographical distribution of genera on this 

 Continent. Plusia simplex G-uenee. occurs in Colorado and other spe-
