Calif. (Apr. 20, 1921); San Bernardino, Calif. (June 8, 1930, 
Hall); San Antonio Canyon, Ontario, Calif. (July 25, 1907). 
Biology, habits, and immature stages. Nothing is known of 
the habits, biology, or immature stages of this species. 
The two specimens which I collected were in much the same 
ecological habitat as that in which one would expect to find 
Pollenia rudis.
