Pachyneuronella, new gen. 



9 . Like Pachyneuron, Walker, but the antennae only 

 11-jointed with two ring-joints, the funicle 4-jointed; 

 abdominal petiole extraordinarily short, so that the abdomen 

 appears sessile ; flagellum short and clavate, the funicle- 

 joints transverse ; scutellum without a cross furrow, the pro- 

 podeum very short, without noticeable carinae nor sulci. 

 Mandibles tridentate but the third tooth broadly truncate, its 

 margin concaved so that four teeth are nearly evident. Third 

 club-joint very short. Marginal vein thickened, about twice 

 longer than wide at apex, the postmarginal a mere spur, the 

 stigmal also very short, merely a minute knob on a very short 

 petiole, not half the length of the marginal, which widens 

 distad. Abdomen convexed beneath near base, as long as the 

 thorax, conic-ovate. Posterior tibiae with one spur.
