26 HYMENOPTEEA. 



This I consider to be probably conspecific with C. zimmermanni. In the latter I find 

 some variation in the colour of the wings and pubescence ; and in the examples I regard 

 as its male the wings are hyaline, smoky at the apex, and the pubescence is cinereous. 

 In fact the difference in the colour of the wings and pubescence is doubtless a sexual 

 character. Out of nearly thirty males before me only one has the wings entirely 

 violaceous.
