Holotype, a female, collected in Mill Creek Canyon, Cal., July 

 20, 1920 (F. R. Cole), in the collection of the California Academy 

 of Sciences.

 related to any species seen by the writer. In Coquillett's table of 

 species it would run to mcrccdis. It is distinct from any de.scribed 

 Mexican species.
