Distribution : Ariz, and N. M. to Vancouver Is., B. C, east to 

 Colo, and E. Canada, thence south into N. J. July to Sept. In a long 

 series we have one specimen labelled June. 



Stramincns was described from specimens taken in the Siskiyou 

 Mts. of S. Ore. in June, and angiistiis from a series taken on Mt. Shasta, 

 Cal., in Aug. The types of both are now in the British Museum, and 

 para types in the Fernald collection. We have specimens compared 

 with the types by Mr. Meyrick and others which we compared in 

 person with Fernald's paratypes, and are unable to find differences 

 which we can regard as specific. The species is rather variable in 

 appearance, due to the inconstancy of the brown shade, but may be 

 easily recognized by the more or less yellow primaries with the brown 

 dot at base of cleft, and the secondaries not conspicuously darker. We 

 know of no other small species which combines these characters. 



Dyar gives the following account of this species as it occurred at 

 Ainsworth, B. C. : 



" * * * The moths were easily started up from low grass and weeds, but 

 especially from the plant Anaphalis nuirgaratacca, which I suppose is their food 

 plant. Larvae were found commonly in the flower heads of this plant, but 

 unfortunately were not bred. The following is a description of them: 



"Larva. — Head shining brown-black, bilobed, the clypeus reaching vertex, 

 rounded at top ; mouth pointed. Body robust, flattened, tapered behind, feet 

 normal, small. Densely covered with brown-black, fiat granules, forming a 

 double patch dorsally, bisected by a pale dorsal line ; ground color whitish, 

 forming a subdorsal band ; segmental incisures shagreened. Tubercles i and ii 

 separate, i dorsally placed, with secondary hairs ; iv and v separate. Later the 

 larva is whitish, with the flat black granules; dorsal, subdorsal, and stigmatal 

 ]nirplish bands, the dorsal band geminately segmentarily bimacnlate in blackish."
