8 PROCEEDIlSrGS OF THE ]SrATION"AL MUSEUM vol. 75 



Male genitalia similar to those of matutina Grote, but larger; 

 figured from paratype in National collection. 



Alar expanse. — 14-21 mm. 



Type. — In collection Barnes. 



Paratypes. — Cat. No. 41205, U.S.N.M., also in American Museum, 

 Canadian National, and Barnes collections. 



Type locality. — San Benito, Tex. 



Food plant. — Unknown. 



Described from male type, 15 male and 3 female paratypes from 

 the type locality ("Mch. 16-23," "Apr. 1-7"), and 12 male and 1 

 female paratypes from Brownsville, Tex. (various February and 

 March dates). 



Closest to totana Kearfott, which it resembles also somewhat in 

 genitalia and from which it differs chiefly in the paler ground color 

 and darker (more blackish) maculations of its fore wing. Follows 

 totana in my arrangement. 



EUCOSMA PERPROPINQUA, new species 



Figure 13 



A pale ocherous or whitish ocherous species of the occipiiana- 

 reversana-daemonicana group with an obscure dark patch in cell of 

 fore wing near base and another on dorsum near tornus (these dark 

 markings almost disappearing in some specimens), three or four 

 rather conspicuous pure white spots on outer half of costa (in 

 females), and veins 3 and 4 of hind wing united. 



Palpus white dusted with ocherous fuscous on outer side. Face 

 and head white. Thorax whitish ocherous. Fore wing white, 

 dusted with pale ocherous fuscous, making the ground color a pale 

 ocherous (in the male type much lighter, almost white); a slight 

 dusting of darker (fuscous) scales on cell near base; on dorsum 

 (or just above dorsal margin) before tornus a faint indication 

 of a similar dark patch; costa of the ground color, weakly striated 

 toward base and, on outer half, with three or four rather broad white 

 spots with some fuscous dusting on the interspaces between (not 

 distinguishable in the male type where the costal markings are 

 obscured by diffusion of the whitish ground color); extreme apex 

 dark; terminal margin below ..apex white; ocellus obsolete, repre- 

 sented by a couple of obscure brown dots or dashes; cilia rather 

 strongly dusted with fuscous and with a distinct white dash just 

 below apex; veins 3, 4, and 5 not approximate at termen; termen 

 straight and slanting. Hind wing nearly concolorous with fore wing; 

 cilia sordid white with a slightly darker basal band and (in dark 

 specimens) a faint indication of a median band; veins 3 and 4 united.
