82 DARALA. 



posterior margin sub-angularly bent backwards ; mesothorax 

 very convex; metathorax sub-elongate, about as broad as 

 long , sloping towards the truncation ; the metauotum bor- 

 dered laterally by a sharp ridge which ends in a short 

 tooth. Intermediate tibiae with a single spine at the apex. 

 Anterior wings with one marginal cell , truncated and ap- 

 pendiculated at its apex, and three submarginal cells, the 

 first a little longer than the two following united , the 

 second, which receives both recurrent nervures before the 

 middle of the base , narrowed towards the marginal cell , 

 the third lunate. Abdomen short , broadly ovate , very con- 

 vex especially at the base, considerably smaller than the 

 thorax , petiolate , the petiole however very short. 



This genus , which in many respects agrees with Lar- 

 rada, may at once be distinguished by the want of the 

 notch on the outside of the mandibles, by the shape of 

 the metathorax and that of the abdomen , etc.

 free , and the space between the curved hind margin of the
