Gelechia unifasciella Busck. 



Two Medicine Lake, July 15-16; in dry mountain meadows. 

 These specimens answer minutely the description of this species, 

 the types of which came from Williams, Arizona, but the expanse is 

 somewhat less (14-15 mm.). 



Gelechia metallica n. sp. 



Palpi bronzy brown, brush on second segment blackish. An- 

 tennae dark brown. Head, thorax and fore wings lustrous dark 

 bronzy brown, the wings entirely immaculate; on underside of the 

 fore wings of the male a patch of yellowish oval slightly convex 

 scales covers the disc. Hind wings shining pale fuscous, with 

 slightly yellowish elongate scales on the disc. Abdomen purplish 

 black above, underside of abdomen and legs shining dark bronzy 

 brown. Expanse, 9.5-11.5 mm. 



Glacier Park Station, July 14 and 29, Going-to-the-Sun, July 20- 

 21; McDermott Lake, July 24; in dry mountain meadows, flying in 

 the early morning. 



Type (cf) and thirty paratypes, all males. 



Very unlike any other described American species. In the hind 

 wing, veins 3 and 4 are stalked, veins 6 and 7 closely approximated. 



Gelechia abradescens n. sp. 



Palpi, antennae and head dark brown; outer side of second seg- 

 ment of palpi witii a few scattered whitish scales. Thorax and 

 fore wings shining dark brown, under a lens slightly irrorated; some- 

 times a few scattered whitish scales along the veins; an indistinct 

 elongate blackish spot at about the middle of the fold, and obliquely 

 above and beyond it in the cell a small blackish spot; a similar 

 but larger spot at the end of the cell; at apical third a whitish spot 

 on the costa, usually confined to the extreme costa, occasionally, 

 especially in the female, extending about one-quarter across the 

 wing. Cilia brownish gray, with a faint line of brown scales through 

 the middle. Hind wings brownish gray, cilia brown at their bases. 

 Underside of body and legs uniformly dark brown without paler 

 markings. Expanse, 17-20 mm. 



Glacier Park Station, July 14, in dry meadows. 



Type (cf) and eleven paratypes (d^ and 9). 



This species seems to be allied to pravinominella, ornatifimhriella 

 and amorphaeeUa. 



The wings are very easily abraded, having then more of a dusted 

 appearance, due to exposure of the paler bases of the scales. In 

 such specimens the black spots are more conspicuous. 



Gelechia conspersa n. sp. 



Palpi pale grayish brown, mixed with whitish, third segment with 

 a minute black spot at the base outwardly. Antennae brown,
