ophor\dae, some of them belonging to genera not reported from 

 this country, were collected. Strangely, no member of the family 

 Tineidae, which is usually well represented in collections from west- 

 ern localities, was secured. 



The types and paratypes of the new species are all for the present 

 in the writer's collection. 



COSMOPTERYGIDAE. 



Cyphophora tricristatella Chambers. 



Occurring most commonly in dry meadows at the lower altitudes 

 in the region (about 5000 feet); one specimen at Granite Park, 

 July 26 (6400 feet). 



Psacaphora deceptella n. sp. 



Palpi dark brown outwardly, with a silvery metallic luster in- 

 wardly; antennae dark brown, apical four or five segments black 

 preceded l^y six or seven white segments. Head and thorax leaden 

 metallic, with a purplish iridescence, base of wing silvery metallic 

 with blue and purple iridescence, followed by a large dark brown 

 patch on costa extending a little below fold. Ground color of 

 remainder of wing golden orange. The dark brown patch is edged 

 outwardly and beneath by bluish silvery metallic scales, which 

 extend outward beneath the fold to a large patch, of dark brown 

 raised scales. A similar large patch of raised scales at tornus, pre- 

 ceded by a streak of metallic scales which forms its inner border 

 and then extends obliquely upward over the end of the cell to the 

 costal cilia ; on the end of the cell these metaUic scales form a slightly 

 convex patch. First discal spot round, silvery, edged with black. 

 A white costal spot at three-fourths. Extreme margin of the wing 

 around apex and cilia dark brown, with a faint purple luster; a 

 row of iridescent metallic scales around apex at base of cilia from 

 the white costal spot to the tornus. Hind wings dark brown. Legs 

 dark brown, tips of segments whitish. Abdomen dark brown above 

 and below. Expanse, 10 mm. 



Type id"), Glacier Park Station, July 29. 



Close to terminella Westwood; at first glance mistakable for it. 

 The chief points of difference are the different coloration of the 

 antennae, the orange apex of the wings, and the details of the silvery 

 markings. 



Psacaphora sexstrigella n. sp. 



Palpi silvery white, the second segment densely dusted with 

 black in transverse rows, third segment with a few blackish specks. 

 Face yellowish, shading to dull leaden metallic on the crown. Tho- 

 rax and fore wings dark brown, mixed with leaden metallic scales, 

 which predominate in the basal two-thirds of the wing. Basal
