Transverse median nervure received very shortly beyond the 

 transverse basal ; the 2"^^ cubital cellule about 3 times lono-er 

 than broad, longer in front than behind ; the recurrent ner- 

 vure almost interstitial ; the radial cellule in the hind winors 

 divided in 2 by a nervure, the basal cellule shorter than the 

 apical. Head large, cubital, the cheeks and occiput margined. 

 Eyes large, curved on the innerside. Palpi long, Prothorax 

 large. Mesonotum trilobate, the middle lobe with a creuu- 

 lated furrow down the centre. Metanotum with a transverse 

 keel in 3 rounded divisions near the base; the spiracles small, 

 oval. Abdomen long, narrow, becoming slightly widened from 

 the base of the 2"'^ to the penultimate segment ; the 1 -^ nar- 

 rower than the others, almost as long as the following 3 

 united ; the 2"'^ about one fourth longer than wide, the basal

Belongs to the Spalhiinae, and to the Tribe Spathiini. Of 

 the Genera in the Tribe it is nearest to Spathius, which has 

 the P^ abdominal segment narrow and clearly separated from 

 the 1"S the 2""^ has no area, the rest form an elongated oval,
