SARCOPHAGA AND ALLIES 121 



The type material was bred from Mdanoplus 

 devastator near Los Angeles, Cal. The writer ex- 

 amined the type in the National Museum, but it was 

 not at hand when the present description was drawn

 with type and was so labeled. The species appears 

 to be an important grasshopper parasite in the West.
