 the underside is bare, hollowed in the middle, the outer sides more 

 acutely pointed and narrower than the inner. Front and vertex 

 strongly punctured and thickly covered with white hair, the front 

 being much more thickly covered than the vertex. Face smooth 

 and shining, stoutly keeled down the middle. Over the clypeus 

 are 6 foveae, close to each other in a row, the outer is the largest ; 

 the sides are furrowed. Mandibles aciculated, and not very sharply 

 pointed at the apex. Thorax thickly covered with silvery pubes-

 on either side of it ; the hair is close and deep black. Scutellum 

 pyramidal ; rugosely punctured, except the upper two-thirds of the 

 base in the centre ; the base has an oblique, straight slope, as has 

 also the apex from below the smooth top, which slightly projects ; 

 the smooth part of the basal slope projects and is clearly separated ; 

 the top is almost transverse ; below the centre are two small fovese. 

 Median segment closely reticulated ; its base thickly covered with 

 depressed silvery pubescence, the apical slope with long white hair ; 

 the basal area reaches to the top of the apical slope ; its basal third 

 is dilated ; the base of the dilated part has the sides straight, the 

 apex has them obhquely narrowed ; the segment has the sides 

 broadly and roundly dilated ; the outer side on the basal half is 

 bordered by a smooth keel. The base of the propleurse is rugosely 

 punctured, the punctured portion being bordered by a row of 

 elongated fovese, which are narrowed obliquely at the apex on 

 either side and are there clearly separated from each other.
