ONTSiRA.^rw. nov. 



Occiput margined. Mesonotum trilobate, the middle 

 lobe furrowed in the centre. Median .segment with ten 

 clearly defined areju. Wing.s with three cubital cellules ; the 

 apical abscissa of the radius curved upwards; the transverse 

 probrachial ncrvure interstitial ; the anal nervure inter- 

 stitial ; the hind wings with only one longitudinal nervure. 

 Head cubital ; largely developed behind the eyes, but not 

 projecting beyond them laterally. Oral region as in 

 Bracon; the mandibles with a sharp apical tooth. Probra- 

 chial areolet as long as pra^brachial ; the radial nervure 

 in hind wings obsolete ; the probrachial cellule divided 

 into two by a nervure. 



The eyes are prominent and distinctly distant from 

 the base of the mandibles ; the antenna have over twenty 

 joints ; the apical ones are broken off; on the under side 

 of the mesopleura; is a wide longitudinal furrow ; the 

 petiole is widely and deeply depressed at the base ; the 

 abdominal segments are smooth, without punctures or 

 depressions of any kind ; there is no securiform articu- 

 lation ; the separation of the segments is hardly 

 distinguishable ; the hinder coxas at the base have a 

 perpendicular slope and are roundly incised there, and 

 in the centre beneath project into a short, somewhat 

 conical, tooth ; the trochanters are rather longer than 

 usual ; the four anterior tibiae are slightly bent at the 

 base ; the calcaria are very short ; the claws simple. In 

 the hind wings the costal and probrachial cellules are 

 distinct ; the probrachial nervure is united to the prai- 

 brachial ; and in the middle of the probrachial cellule is an 

 oblique nervure dividing it into two ; the radius is 

 obsolete; the cubitus complete, extending to the ape.x ; the 

 probrachial nervure is obsolete ; the probrachial and the 

 anal cellules beine thus united into one.
