The species is closely related to simplex Sm. from Colorado, is 

 however slighter in build and the color of primaries is considerably 

 deeper, lacking the greenish tinge of simplex. We have seen no 

 female specimens of this latter species with pink suffusion. 



PROCHLORIDEA, new genus. (Type P. modcsta sp. nov.) 



Proboscis fully developed ; palpi upturned to slightly beyond front ; front 

 with rounded protuberance, without infra-clypeal plate; eyes naked, rounded; 

 mid-tibiae spined ; hind tibiae unspined ; fore tibiae with a slender apical spur 

 on outer side and 3 or 4 spines considerably above it, a similar spur on inner 

 side with a minute spine just behind ; head and thorax clothed with hair and 

 scales ; venation as in Schinia. 



This genus seems best associated with Chloridea and Oxylos, 

 according to Hampson (Cat. Lep. Phal., Vol. IV) ; we have been 

 unable to find in the tables of genera any with unspined hind-tibiae, 

 a feature which is certainly shown by the specimens before us. In 

 this respect Prochloridca approaches Grotella, which is supposed to 

 bear a single spine on hind tibi?e between the spurs ; we have how- 

 ever noted specimens with entirely unarmed hind-tibise. In general 

 appearance modcsta resembles a Homohadcna. but the spined mid- 

 tibise and peculiar structure of the fore-tibix preclude this associa- 

 tion. 



Prochloridca modesta, new species. 



Female. — Front ochreous ; head and thorax clothed with brown scales and 

 hairs, intermingled with white : abdomen gray, smoothly scaled ; primaries 

 brown, irrorate slightly with darker in and beyond the cell and on inner 

 margin ; all maculation very indistinct ; a slight basal streak extending below 

 cubitus half way to origin of vein Cuo ; t.a. line absent or represented by a few 

 indistinct dentate marks above inner margin ; orbicular absent : reniform 

 represented by a slight white mark ; t.p. line very obscure, dentate, only 

 traceable by some whitish shading immediately following it ; terminal space 

 somewhat lighter with several obscure dark dashes, most prominent opposite 

 reniform ; fringes light brown checkered with darker. Secondaries white, 

 with slight smoky traces along outer margin ; veins more or less defined in 

 brown. Beneath white, irrorate with brown scales along costa and outer 

 margin.

Habitat.— Ft. Wingate, N. M. 4 ? $. Types Coll. Barnes. 

 A very obscurely marked species in which the most noticeable 

 feature is the white dot in the position of the reniform.
