CRABRO CEPHALOTES. M7 



basal joint of the intermediate tarsi produced beneath towards 

 the apex, and having two stout spines. Abdomen : each seg- 

 ment with a yellow interrupted fascia ; the fifth fascia generally 

 entire. 



Having collected these insects upwards of twenty years, and 

 having examined hundreds of individuals without meeting with 

 any female at all likely to belong to C. sexcincttis, except C. ce- 

 phalotes, I quite agree with Shuckard that this is probably a 

 variety of the next species. I have not bred this species or va- 

 riety, but have reared C. cephalotes from decaying willow wood.

C. niger, flavo-maculatus ; clypeo aurato ; mesothorace et scutello 

 longitudinaliter rugosis ; tibiis flavis, abdomineque fasciis in- 

 terrupts fiavis.
