 Long. 9-10 mm. 



Scape of antennae shining, sparsely punctured, above with 

 a few white hairs ; the flagellum stout, distinctly tapering 

 towards the apex ; opaque, covered with a pale down ; the 

 third and fourth joints equal in length. Vertex shining, 

 behind the ocelli coarsely and closely punctured, at their sides 

 much more sparsely punctured ; the ocellar region distinctly 

 raised, strongly punctured all over ; the ocelli are placed at 

 the sides of the raised part. Clypeus raised gradually from 

 the base to the apex, the sides also raised ; the apex is deeply 

 and roundly incised in the middle, the sides at the apex 

 appearing as stout, large, bluntly triangular teeth ; the apex 

 on the lower side truncated. Mandibles with only one long- 

 apical tooth ; the tooth on the lower side behind the middle 

 is large, the base is punctured and covered with long white 

 hair. Pronotum coarsely punctured, its hinder edge dis- 

 tinctly raised ; the pleurse have some stout, irregular, oblique 

 keels ; in front of the tegulse is a large patch of dense silvery 

 pubescence ; the remainder is sparsely covered with long pale 

 hair. Scutellum not much raised, shining, the sides bearing 

 large, deep, widely separated punctures and long black hairs ; 

 the middle is smooth and shining ; there is a furrow down 

 the base in the middle and a longer one, slightly narrowed in 

 the middle, on the apical part. The basal half of the median 

 segment has a thick covering of white pubescence which com- 

 pletely hides the texture ; the apex has an oblique slope, is 

 reticulated and covered rather thickly with long fuscous hairs. 

 Mesopleuraj coarsely punctured in the middle, thickly covered 

 with longish white hair ; the apical half of the metapleurse 

 reticulated. Legs thickly covered with white hair ; the
