Canadiayi records 

 British Columbia: Vernon (20-XI-1927, A. A. Dennys). 



Remarks. — This species seems to be confined to far-western North 

 America, where it is rather widely distributed. It was originally 

 described from specimens collected by Lord Walsingham on Mount 

 Shasta, Calif., and in North Oregon. Busck ^^ also records specimens 

 from Arizona. He further states that Dyar bred a specimen from 

 Helianthus pumilus collected near Denver and Sedalia, Colo. 

 Braun -* bred three specimens from BalsamorMza sagiftata collected 

 near Logan, Utah.
