270 BULLETIlSr 123, UNITED STATES NATIONAL MUSEUM. 



Very close to suhplicana Walsingham and possibly a local race of 

 that species; but quite different in color and easily distinguished. 

 Until we know more about them the two had better be regarded as 

 separate species. 



ANCHYLOPERA DEFINITIVANA, new species. 

 (Fig. 432.) 



Fore wing whitish ochreous with a black smudge at end of cell, 

 a shading of ochreous beyond, broken by a pair of indistinct longi- 

 tudinal black streaks, some blackish dusting toward tornus and an 

 argus brown basal patch; outer margin of basal patch straight, de- 

 cidedly slanting, and outwardly margined by a few black scales; 

 costa marked with fine black geminations; around apex and along 

 termen nearly to tornus, a fine black line; cilia whitish ochreous. 

 Hind wing very pale smoky fuscous, inclining to whitish ochreous. 



Male genitalia of type figured. 



Alar expanse. — 14.5 mm. 



Type.—Q2it. No. 25622, U.S.N.M.

Food plant. — Unknown. 



Described from single male labeled "Nevada, July 16-23." A 

 distinct species easily recognized on pattern and genitalia. It is 

 the only one with a black smudge at the end of the cell on fore wing, 

 and the only one having at once an uncus and so long and slender 

 an aedoeagus. 



HYSTRICOPHORA OSTENTATRIX, new species. 



Antennae, palpi, head, and thorax brownish gray; face, under- 

 side of antennae, and inner sides of palpi paler, more whitish ochre- 

 ous. Fore wing brownish-fuscuous-gray dusted with scattered 

 white and some few black scales; from slightly beyond middle of 

 dorsum to middle of costa a faint, biangulate, darker gray fascia; 

 a similar dark shade on dorsum before ocelloid patch; ocellus an 

 obscure vertical metallic bar inwardly bordered by three black 

 streaks and outwardly by three black dots and a white or whitish- 

 ochreous elongate patch near termen above tornus; ground color 

 near apex also more ochreous than gray; costa between fascia and 

 apex marked with four black spots alternating with narrow white 

 streaks; dorsal margin faintly dotted with black; cilia whitish 

 ochreous, blotched with smoky blackish fuscous above tornus. Hind 

 wing brown; cilia only slightly paler. 



Male genitalia as in roessleri Zeller, except with fewer cornuti. 



Alar expanse. — 28.5-29 mm. 



Type. — In collection Barnes.
