Kedescribed from a female in the collection of W. J. Chamberlin, 

 collected at Elsinore, Calif., during May 1931, and identified by Dr. 

 Van Dyke. 



Male. — Not seen. 



Type locality. — Santa Monica hills, near Santa Monica, Calif. ; type 

 in the California Academy of Sciences. 



Hosts. — The larval habits of this species are not known. Chamber- 

 lin (1926) gives the hosts as Baccharis sergiloides Gray and Bac- 

 eharts pilularis De Candolle, but these records are from misidentified 

 specimens and should apply to beyeri and hacchari. 



The only specimen seen by the writer is the female from which the 

 above redescription was made.
