 Bentyra, gen. nov. 



Median segment deeply depressed at the base ; there is one 

 transverse keel, behind which the segment is closely transverse- 

 ly striated ; the spiracles small, oval. Areolet absent ; the 

 transverse basal nervure interstitial ; disco-cubital nervure brok- 

 en by a stump. Parapsidal furrows deep ; a wide, deep depres- 

 sion at the base of the scutellum. A deep, oblique furrow on 

 the basal half of the mesosternum. Eyes large, temples and 

 malar space small. Olypeus roundly convex, not separated from 

 the face ; its apex minutely bituberculate. Mandibles stoutly 

 bidentate, the teeth of equal size. Petiole stout, becoming
