Descriptions. 



The list^ of references for this genus by Dalla Torre in his Cata- 

 logue Hymenopterorum, Vol. X, are so full in most cases that it has 

 seemed unnecessary to give complete lists. However, all references 

 of literature knov^^n to me since Dalla Torre will be given, thereby 

 making the list as complete as possible.
