CRABRO VARIUS. 129 



Abdomen subclavate, subpubescent, and shining; the apical 

 segment flavo-testaceous. 



The Female not known. 



Dahlbom considers this species a variety of C. elongatulus ; 

 but in this opinion I do not coincide, having taken numbers of 

 the latter from their nests. I have found little variation in their 

 colouring; the palpi are more yellow in some than in others; but 

 I have never found the legs and tarsi ornamented with yellow as 

 in this species.
