Head above and down the middle of the forehead black, the 

 rest tawny testaceous ; eyes in male not touching the median 

 line of forehead, in female a little more distant. Antennai 

 short and stout, black ; apex tawny. Thorax ovate, much 

 narrowed behind and convex in front, densely pubescent, 

 coarsely and closely punctured. Elytra reaching nearly to the 

 apex of the penultimate segment, subulate, but not very nar- 

 row, parallel from after the base, obtusely pointed at the apex ; 

 the vitreous yellowish disk has a few very fine setiferous 

 punctures ; a black fascia curves near the base behind the 

 scutellum, and joins on each side a short streak on the top of 

 the shoulder ; the margins elsewhere are narrowly castaneous. 

 The legs are moderately stout ; the hind thighs not clavate, 

 but gradually and moderately thickened. The petiolated 

 basal segment of the abdomen is partly yellow; the very convex 

 metasternum and margins of the ventral segments are clothed 

 with golden pile.
