WASP GENUS CERCERIS — SCULLEN 445 



The female of C. compar orestes Banks closely resembles C. compar 

 compar Cresson, but the former can be separated by the absence of a 

 band of yellow on its tergum 2 and the presence of a hook-shaped 

 patch on its propodeum. It also resembles C. insolita, but the former 

 can be separated by the shape and size of its clypeal process and its 

 hook-shaped yellow patch on the propodeum.

 August 1-4 (Bequaert), is at the Museum of Comparative Zoology,
