sternum is rounded laterally, covered with deeper and broader foveae 

 than even the scutellum, and is without longitudinal keels ; first 

 abdominal segment somewhat short, the petiole angular laterally, 

 plainly carinate on each side underneath, and having in the centre a 

 very sharp well-developed keel, it is truncate at apex and covered 

 above and below with deep and closely set punctures ; on the second 

 segment these punctures are broader and more scattered on both the 

 upper and lower sides, those of the other segments are small and 

 very closely set ; apical segment with a smooth longitudinal median 

 line not reaching the apex ; wings very dark fuscous, radial cell 

 truncate at apex, stigma very small, three closed cubital cells and 

 two recurrent nervures, the first uniting before the middle and the 

 second at the apex of the second and third cubital cells ; tibial spurs 

 black. 



Length 16 mm. ; width (wings expanded) 28 mm.

J . Black, clothed with a very dense and very long setose 1)1 ack 

 pubescence turning to greyish on the under side of the abdomen, 

 and less distinctly so on the anterior part of the pronotum ; abdomen 

 sub-sessile, ovate, second segment with a narrow apical border of 

 white pubescence ; wings sub-hyaline at base and infuscated for the 

 greater part of the length. 



Head broader than long, deeply and very closely pitted, ej^es not 

 emarginate inwardly, about equi-distant from the insertion of man- 

 dibles and from the hind margin which is straight with the angles 

 slightly rounded; ocelli very distinct; second antennal joint one- 

 third shorter than the third ; thorax as broad in front as the 

 head, pronotum with the anterior border straight and the angles 

 distinct, slightly ampliated diagonally towards the tegulae which are 

 large, convex, and less broadly pitted than the rest of the thorax, 

 the suture with the mesonotum is indistinct, the mesonotum itself 

 has no keel or carinule ; the scutellum is broadly arcuate, very 

 sloping, but somewhat convex and densely hairy black ; the meta- 

 sternum, which is short, follows the angle of the sloiie of the 

 scutellum, and is broadly pitted, rounded laterally, and simple ; 

 abdomen ampliate ovate, first segment as broad as long on the upper 

 side and with the peduncle very slanting, carinate on each side 

 underneath and having a very sharp median keel all along the 

 length ; it is less deeply and broadly pitted than the ampliate second
