its posterior angles, the tegulse, a spot below the tubercles, the pos- 

 terior angles of the scutellum, and the raised margin of the post- 

 scutellum flavo-testaceous, abdomen with the 1st segment, except 

 a basal triangular spot, testaceous, the other segments black 

 with a trisinuate testaceous apical band, legs with the apices of the 

 femora, the tibia? and tarsi rufotestaceons. Head closely and coarsely 

 punctured, mandibles tridentate, clypeus deeply and angularly 

 emarginate, apical joint of the antennae small, slightly curved and 

 subtruncate; thorax punctured very similarly to the head, prothorax 

 truncate in front, its angles not produced and nearly rectangular ; 

 wings slightly dusky especially along the costal margin, nervures 

 brown, clear testaceous towards the base of the wings ; 2nd recurrent 

 nervure received near the base of the third submarginal cell ; 

 post-scutellum flattened and produced horizontally over the pro- 

 podeum, slightly emarginate posteriorly, its margins reflexed, a 

 strong carina runs along the sides of the propodeum, below which 

 the surface is bright and shining ; abdomen strongly punctured 

 1st segment cupuliform, its apical margin slightly raised. 



$ . Very like the <£ and similarly punctured, but with the base 

 and under-side of the antenna?, the mandibles, the head posteriorly, 

 and a spot in the sinus of each eye rufotestaceous ; on the face, its 

 apex between the insertion of the antenna?, is a triangular spot of a 

 paler testaceous colour, clypeus only slightly sinuate at its apex, 

 pronotum truncate with its angles more produced than in the g , and 

 if anything slightly less than a right angle, flavotestaceous in front 

 blending through a brownish colour into black posteriorly ; wings as 

 in the $ . Sides of the propodeum rufotestaceous, abdomen with the 

 basal segment rufotestaceous, its apex of a more flavous tint, its 

 disc with a round blackish spot, the rest of the segments black, 

 with a testaceous trisinuate apical band, more or less margined with
