* Pristiphora, Latr., is merely a section of Nematus, founded on the presence 

 of three instead of four subniarginal cells, a character which is not constant in 

 Remains, even in the same species. St.-Fargeau extended it to include Euura; 

 but it is now restricted provisionally to a species with very remarkable neura- 

 tion, which has not been seen since it was first described. When rediscovered, 

 it will require a new generic name; for Pristiphora, as already explained, is 

 inadmissible.
