stouter; the base of the median segment is more strongly 

 reticulated, the central fovea larger and deeper ; and the 

 apex is strongly transversely striolated. 



Head black ; the front and vertex sparsely covered 

 with long pale fulvous hairs ; the clypeus almost bare ; 

 the vertex closely punctured ; the clypeus with the 

 punctures larger and more distinctly punctured below ; 

 projecting between the antennae is a raised space, very 

 smooth, shining, and triangular at the top ; transverse 

 at the bottom and with a few large punctures. Antennae 

 black, almost glabrous. Thorax densely covered with 

 long pale fulvous hairs ; the median segment at the base 

 almost glabrous ; the triangular space in the middle at 

 the base aciculate, the apex shining, impunctate ; the 

 sides more strongly aciculated. Pleurae shining, impunc- 

 tate. The hairs on the femora fulvous ; on the tibiae and 

 tarsi blackish : the middle tarsal joints testaceous. The 

 wings have a decided fusco-violaceous tinge beyond 

 the transverse basal nervure ; the nervures and stigma 

 in the centre fuscous ; the tegulae pale testaceous. The 

 basal segment of the abdomen thickly covered with long 

 pale testaceous hairs ; the other segments thickly covered 

 with black hairs, except at the apices which are fringed 

 with white depressed hairs ; the basal half of the ventral 

 segments smooth, glabrous ; the apical fringed with 

 longish black hairs ; the pygidium glabrous, shining, 

 impunctate ; the lateral furrows wide, covered all over 

 with long pale fulvous hairs, closely and rather strongly 

 punctured ; the punctures larger and more widely sepa- 

 rated towards the apex ; the base of the scutellum almost 

 impunctate ; the base of the median segment with short 

 stout keels ; those at the sides being longer and sharply 

 bent in the middle ; the middle before the basal keels 

 coarsely reticulated ; ' in front of this again is a large, 

 somewhat pear-shaped, shining; impunctate depression ;
