It is diflicult to understand why Cameron lias made such 

 confusion in dealing with the genera and subgenera under 

 Odynerus. Ancistroceriis, Wesm., is given both g^eneric and 

 subgeneric rank in two consecutive species, and the same is 

 true of JS^orfom'a, which is also placed as a subgenus of 

 Odynerus and Ancistrocerus ! 



The species of Odynerxis described as new in the results 

 of the Kilimanjaro-Meru Expedition may be separated by 

 means of the following key : —

 Pronotum black, anterior margin yellow ; 



postscutellum yellow kibonotensis, $ .
