the genus Odynerus occurring in the Ethiopian Region. 513 



that when working through the Banks collection for 

 additions and corrections to his Monograph, Saussure fixed 

 on the first specimen labelled " F. lateralis " as the true 

 exponent of the Fabrician species, synonymising the more 

 recently described R. africanum, F. (1804), with it. Now, 

 however, the name R. africanum can be reinstated.

 the abdomen entirely smooth.

 busque plerumque fusco-ferrugineis ; abdomine plerumque nigro ;
