Note. — It has been suspected that Phorhas Ashmead was 

 the male of Bacchus Ashmead and that Eukoebeleia Perkins was 

 synonomous with the latter. The difference mentioned is that 

 Bacchus has a four-jointed maxillary palpus while that of 

 Eukoebeleia is five-jointed. Examination of Ashmead's type 

 specimen of Bacchus showed that it had a five-jointed maxillary 

 palp, and that the male of Eukoebeleia was synonymous with 

 Phorbas. In Kieffer's key to Bocchus (1914) it is mentioned as 

 having bare eyes. There is no note of this is Ashmead's descrip- 

 tion and those of his type were slightly hairy. Since the females 

 of Phorbas have not been described it is impossible to include 

 such species in the following key:
