30 Cameron, Hymenoptera, from GreynioutJi. 



fuscous ; the transverse cubital nervures united at the top ; 

 the recurrent nervure is received in the apical third of the 

 cellule. Legs black, thickly covered with longish white 

 hair ; the base and apex of the anterior tibiae and the fore 

 tarsi for the greater part testaceous. Abdomen strongly 

 punctured, thickly covered with short pale hair ; the 

 petiole strongly keeled down the centre to shortly beyond 

 the middle ; the base not much depressed in the centre. 



The two species I have here referred to Chorinceus 

 agree better with that genus than with any other. The 

 keels on the second and third abdominal segments charac- 

 teristic of Chorinceus can hardly be said to exist ; the 

 femora and the legs generally are stouter than they are in 

 e.g. the European C. fitnebris ; while both species differ in 

 the areolet being complete.
