The following key will be useful for the separation of the above 

 species of Coelioxys: 



Scutellum red, with a large median process hcrmatiira Ckll. 



Scutellum black, without such a process i 



1. Scutellum strongly angulate in middle, the apical region smooth ; hair at 



base of scutellum forming two large widely separated spots. 



tumorifera Ckll. 



Scutellum not strongly angulate in middle; hair at base not in two widely 



separated spots ^ 



2. Scutellum short, strongly punctured all over; first abdominal segment above 



j)]3^(,j^ leucochrysea Ckll. 



Scutellum longer, subangulate, smooth in middle; first abdominal segment 

 above light red rufibasis Ckll.
