parently they agree with the specimens mentioned as received by 

 him after the description had been drawn up. In the hind wings 

 vein 4 is absent. 



Thiodia stygiana, n. sp. 



A large species without costal fold in the J\, the outer margin 

 very distinctly sinuate ; hind wings with veins 3 and 4 stalked. 

 5 arising very near the base of the stalk. 



Fore wings sordid russet brown, in some specimens shading to light 

 gray on the costal edge, irrorate with brown; markings obsolete. The 

 brown tends to lie in strigse along the costa, and very faintly forms oblique 

 lines on wing; it is darker and solid along internal margin. In the place 

 of the ocelloid patch are scattering black scales or dots. Fringe pale, 

 lustrous shining with a brown subbasal line. Hind wings and abdomen 

 brown black, very dark, contrasted; anal tuft light brown; fringe as on 

 fore wings. Expanse, 27-31 mm. 



One J from Williams, Arizona, and five other specimens from 

 Colorado (Golden, May 29, June 9 and 19, Dyar and Caudell). 



Type. No. 6745, U. S. National Museum/ 



I should certainly have supposed this large and conspicuous 

 species to have been described before, as it seems not rare in the 

 eastern foothills of the Rocky Mountains, but I am unable to find 

 a description applicable to it. It resembles Lord Walsingham's 

 figures of Pcedlsca irroratana, perdricana andfutminanaibut 

 the four males before me show no sign of the costal fold. 



I have a much paler specimen in which the gray occupies nearly 

 all the wing and the black dots on ocelloid patch are distinct, from 

 Easton, Washington (A. Koebele, through C. V. Riley), which 

 suggests Zeller's figure of T. rcessleri, and my stygiana may 

 prove to be a form of that species. 

 5210. Proteopteryx emarginana Wals. 



One specimen like Lord Walsingham's figure 2. 

 5222. Epinotia lagopana Wals. 



One fresh Q specimen, July 23. 

 Epinotia favillana, n. sp. 



Male without costal fold, outer margin of fore wings not sin 

 uate. Resembles somewhat Lord Walsingham's figure of 

 Pcedisca carolinana, but with differently disposed markings. 



Fore wings white with a faint purplish tint, heavily marked with black 

 ish brown. A broad, dark basal area with edge indented on costa, cell 

 and subrnedian fold, mixed with white scales toward base; a broad 

 median band from costa to internal margin, its edge nearly straight, with 

 some black and leaden scales toward costa; costal edge with dark strigae ; 

 terminal third of wing with white ground prevailing, the margin edged 

 with brown black, broadest at apex; a large dark spot subterrninally be 

 tween veins 5 and 7, continued as a slightly oblique band to inner margin
