United States records 



Colorado: Golden, $ (Dyar and Caudell, no date). 



Washing'ton: Snake River, Whitman County, opposite Clarkston, 3 5 5,39 9 

 (V-3()-31, VI-4 to 18-33, and V-11-34, J. P. G. Clarke). 



Remarks. — With Busck's unique type male I associate six reared 

 specimens from the Snake River, AVash. (Clarke Nos. 2944, 4416, 4417, 

 4418, 4419, and 5209) . The Washington specimens fit the description 

 in every detail except that some of them show two discal spots, the 

 single discal spot not being present. In specimen 5209 veins 3 and 

 4 of the hind wing are short stalked as described, but in the remaining 

 specimens they are connate. In spite of tlie variation in venation it 

 would be illogical to consider the Washington specimens anytl.dng 

 but one species. The male genitalia show some slight variation in 

 the length of the harpe and shape of the cucullus, but this is not 

 significant.
