This species is very close to artemisiella Kearf . ; the two are ahnost 

 identically marked, but erigeronella is a narrow, more slender-winged 

 species and is considerably larger. 



Gnorimoschema contxaria n. sp. 



Labial palpi blackish, minutely peppered with white; second seg- 

 ment whitish inwardly, third with a white spot within near base. 

 Antennae dark brown with narrow paler rings. Head and thorax 

 dark fuscous, patagia and tip of thorax reddish brown. Costal 

 two-thirds of the fore wing reddish brown, with the costa and veins 

 marked with lines of white broadly black-barred scales, the lines 

 sometimes confluent in the apical half of the wing; the dorsal third 

 of the wing from the base to the apex is clothed with white scales 

 barred before their tips with black of varying width. The dorsal 

 margin is distinctly lighter than the remainder of the wing. The 

 paler dorsal portion is irregular indented with blunt tooth-lik3 

 projections of the brown ground color; these teeth are partially 

 filled up and edged with blackish scales, heightening the contrast*., 

 between the two areas. Three of these patches of black scales stand 

 out prominently; an elongate one near base, one in each of the two 

 succeeding teeth and extending up onto the cell. Cilia fuscous, 

 specked Avith whitish black-barred scales. Hind wings and cilia 

 gray, with a faint reddish tinge. Legs densely dusted with fuscous. 

 Expanse, 15-16 mm. 



Type (cf ), McDermott Lake, July 22; three paratypes (cf and 9 ), 

 Glacier Park Station, July 14; in dry meadows. 



Although allied to the other longitudinally streaked species, the 

 paler dorsal margin gives it a very different aspect; the pattern 

 of the dorsal half of the wing is that of serratipalpella Chambers. 

 In the female, the brown ground color is less obscured by the dusted 

 lines than in the males. 



Anacampsis niveopulvella Chambers. 



Common at Glacier Park Station, where the larvae feed on willow 

 and aspen. Both this and the following species are referable to 

 Compsolechin Meyrick, if this genus is maintained distinct from 



A7iacaittpsis. 



Anacampsis paltodohella Busck. 



(Jne specimen of this beautiful species taken on the car window, 

 exact locality not known, presumably western Montana. 



The type locality is New Mexico. 



Gelechia lugubrella Fab. 



McDermott Lake, July 22; Glacier Park Station, July 29; in dry 

 meadows. Previously reported in this country from Maine.
