I have seen no specimens from the type locality that answer to 

 Walsingham's description and figure and nothing that could with 

 certainty be referred to his name. The only specimens I have seen 

 that seem to fit both description and figure are a male from Los 

 Angeles County, California ("Apr.") and two specimens from 

 Olancha, Inyo County, California. One of the latter is in the 

 Barnes collection. The other and the specimen from Los Angeles 

 County are in the National Collection. Pending examination of 

 the actual type I am referring them here. 



The male genitalia is figured from the Olancha specimen in the 

 National Collection. 



Alar expanse. — 10-12 mm. 



Type. — In British Museum. 



Type locality. — Siskiyou County, California.
