Fringes cut with white. Hiud wings blackish with white fringes, reflecting 

 the band and dot of under surface. Beneath, a terminal series of black dots, 

 very obvious and plain on primaries above. Body blackish fuscous. Ex- 

 panse 25 mil. No. 1044. Prof. Snow, New Mexico. 



HOMOHADENA EPIPASCHIA n. S. 



This singular species has the look of one of the EpipascluK. Fore wings 

 clayey gray, much shaded with black. Lines black, single; t. a. somewhat 

 curved and thick; t. p. line widely bent, with an acute costal tooth towards 

 base of wing; s. t. line denticulate, pale, followed by prominent interspaceal 

 black marks, the black terminal space itself cut by pale veins; fringe dark. 

 Hind wings blackish fuscous. Beneath, two bands on primaries and ter- 

 minal black mark^ more faintly repeated; hind wings gray, with the band 

 bent subtermiually; a discal point. Above, a black cloud on center of disc 

 apparently separating the pole, black clouded, undefined stigmata. Expanse 

 30 mil. No. 1013. 



CopiMAMESTRA Grote. 



The types of this genus are the European Brassicce and a new North Amer- 

 ican species which agrees with it in structure and differs in color, so that the 

 two species must have a common origin. Characters of Mamestra, except 

 that fore tibise have a distinct claw. So long as one species alone was de- 

 scribed, a separate genus might not be thought necessary. This remarkable 

 addition to our Western fauna illustrates my theory that the northern forms 

 in our North American fauna carae by the north before the glacial epoch. 

 (See my papers in Popular Science Monthly, Silliman's Journal, etc.) In the 

 present case the species has not come east to our seaboard, as far as known. 



COPIMAMESTRA OCCIDENTA n. S. 



Eyes hairy. More blackish than Brassicce. A greenish-white before s. t. 

 line, continuous. Reniforra greenish- white; a patch of same color on sub- 

 basal field. Orbicular not well marked. Lines black. Tegulse lined with 

 black. Hind wings pale, shaded outwardly. Discal spot on fore wings be- 

 neath pale, with central dot; on the whitish secondaries a solid dot. Expanse 

 42 mil. No. 943. 



This genus may be objected to, but I cannot see any reason for over- 

 looking the claw in Copimamestra and regarding it as of generic value in 

 Oncocnemis. The sweeping criticism passed on my ideas of genera by Mr. 

 Smith conveys an erroneous idea. I regard them as artificial groupings to a 

 great extent, but I would not mix up species with armed and unarmed tibise, 

 hairy and naked eyes, in one genus. I may have insisted too strongly on the 

 value of single characters by themselves, but this is the extent of my fault, 

 and it is largely one upon which an opinion is justifiable. The best reply is 

 that Mr. Smith's adopted genera are sometimes based on single characters, 

 and again on "modifications of a modification." For my part I cannot
