ANCYLIS ALBAFASCIA, new species 



Figure 5 



A dark brown species with a narrow Avhite transverse fascia on 

 fore wing from costa before middle to outer third of dorsum. 



Palpus white, shaded with pale fuscous on outer side and toward 

 apex. Head and thorax glossy fuscous brown. Fore wing very dark 

 brown; costa with two pairs of short white dashes before middle and 

 four pairs on outer half; from the first pair of antimedial costal 

 dashes a narrow but somewhat irregular band of white scales extends 

 to outer third of dorsum, forming to the naked eye a thin white 

 transverse fascia; no ocelloid patch; in terminal area a couple of very 

 obscure, thin, semimetallic curved bands continue from the first and 

 and second postmedian pair of white costal dashes (not visible 

 except under magnification); some faint white scaling at termen 

 near tornus; cilia shining metallic fuscous with a couple of strong 

 white dashes below apex, at extreme apex of the general wing color. 

 Hind wing dark brown, but slightly paler than fore wing; cilia paler 

 with a dark basal band, the scale ends toward apex whitish. 



Male genitalia figured from type. 



Alar expanse. — 11-14 mm. 



Tyjye. — In Barnes collection. 



Paratypes. — Cat. No. 41215, U.S.N.M.; also in American Museum 

 and Barnes collections. 



Type locality. — Mineralking, Tulare County, Calif. 



Food plant. — Unknown. 



Described from male type, four male and three female paratypes 

 from the type locality ("June 24-30" and "July 1-7"); one male 

 paratype and two female paratypes from San Bernardino, Calif. 

 ("June 1-7"). 



A distinct species, not to be confused with anything else in the 

 genus. In genitalia nearest to unguicella Linnaeus, which species it 

 precedes in my arrangement, but with much slenderer harpes. 



HYSTRICOPHORA OCHREICOSTANA (Walsingham) 



Figure 29 



In a paper published in the Journal of the Washington Academy 

 of Sciences (vol. 14, No. 16, 1924, p. 393) I expressed the opinion that 

 ocTireicostana was nothing but a variety of taleana Grote. I had 

 noted the differences in the harpes of the two and the color differ- 

 ences on basal half of costa of fore wing, but had overlooked entirely 

 a very striking character in the tergite of the eighth abdominal seg- 

 ment. In taleana this part is distinctly excavate, while in ocTireicost- 

 ana it is produced as a blunted triangle (compare figs. 27, 29). Such
