Crabro pugnans Sm. 



Chapada (April). One specimen. Pugnans belongs to the group 

 Crossocerus. 



Crabro carinatus Sua. 



Two specimens. Pedra Branca (April) ; Rio de Janeiro (Novem- 

 ber). Seems to belong to Solenius group, as characterized in Kohl's 

 table. 

 Crabro verticalis Sm. 



Fourteen specimens, all females. Chapada (January, March, May, 

 December). This species apparently belongs to Crossocerus group. 



Crabro atitlanse Cam. 



Two specimens from Rio de Janeiro (November) and Benivedes 

 (July) I refer with some doubt to atitlance. If not identical they 

 are closely allied.
