112 AMERICAN HYMENOPTERA. 



cies because the name carbonarius had been preoccupied by 

 B. carbonarius Menge, 1856, from Prussian amber. In the 

 collection of specimens of South and Central American spe- 

 cies before me, made up of specimens from a considerable 

 number of different collections, there are only four specimens 

 of this species while of niger there are fifty-two specimens. 

 It seems probable, therefore, that both vehitimis and violace- 

 ous were niger. It should be noted, however, that, when 

 Handlirsch described this species, there were twenty-seven 

 specimens of it in the collection of the Vienna Hofmuseum 

 while there were apparently only thirty-six specimens of 

 niger. So, while the chances seem to be in favor of Illiger's 

 and St. Fargeau's having had niger, it is quite possible that 

 they made their descriptions from specimens of either spe- 

 cies or of both species mixed. 



B. kohli appears to have its closest allies in carolinus and 

 dahlboniii.
