18 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 75 



Male genitalia as in hurgessiana. 



Alar expanse. — 13-15 mm. 



Type and paratypes. — Cat. No. 41213, U.S.N.M.; also paratypes 

 in American Museum, Canadian National, and Barnes collections. 



Type locality. — Chimney Gulch, Golden, Colo. (Oslar). 



Food plant. — Unknown. 



Described from male type, female paratype, and four male paratypes 

 from the type locality, dated "April" (type and three other males), 

 "6-14-07" (female) and "7-15-04" (one male); one male paratype 

 from Clear Creek, Colo. (Oslar, "5-30-07"); and one female paratype 

 from Denver, Colo. (Oslar, "6-14-04 "). 



Besides the above I have before me specimens from St. Johns, 

 Quebec (W. Chagnon, "3-VI-14," male without abdomen), Palos 

 Park, Chicago, 111. (A. Kwiat, "VI-4-04," male without abdomen). 

 New Hampshire (male, no date), Wisconsin (male, no date), and 

 Vavenby, British Columbia (Theo. A. Moilliet, "22-V-1924," Black- 

 more No. 797, male). 



This is the form to which I referred in my revision of the Eucos- 

 minae (U. S. National Museum Bull. 123, p. 242) as a possible variety 

 of platanana Clemens. I am inclined now to believe that it is a good 

 species, closer if anything to hurgessiana than to platanana. 



ANCHYLOPERA MIRA FURVESCENS, new variety 



A dark variety and presumably a food plant race of the preceding 

 species. Ground color of fore wing more suffused with fuscous, 

 especially in terminal area; basal patch very dark brown; outer bar 

 dark red and more diffused, the red blending into the fuscous of the 

 terminal area, which has none of the contrasted yellow color of typical 

 mira. Hind wing smoky fuscous; cilia slightly paler, sordid. 



Genitalia as in typical mira. 



Alar expanse. — 12.5-14 mm. 



Type. — In American Museum. 



Paratypes. — Cat. No. 41214, U.S.N.M.; also in Canadian National 

 and Barnes collections. 



Type locality. — New Haven, Conn. 



Food plant. — Unknown. 



Described from male type from the Kearfott collection of the 

 American Museum (" VI-10 ") ; one female paratype from the Fernald 

 collection without locality label; two female paratypes from New 

 Hampshire (one from Dublin, August Busck, collector; the other with 

 only the New Hampshire label) ; and one female paratype from 

 Quebec (A. W. Hanham "266"). 



In color much like the European derasana Hiibner.
