 small tufts of tawny hairs placed on two feeble elevations. 

 Prothorax with two small tubercles on each side of the disk, 

 the two hinder ones being in a line with the lateral tubercles, 

 with a broader but more feebly raised tubercle in the middle, 

 a little in front of the base. Elytra somewhat rugose towards 

 the base, but with the rugosity scarcely evident, owing to the 

 closeness of the pubescence. Legs and first joint of the 

 antenna' slightly mottled with brown or tawny. Each of the 

 abdominal segments with a short fringe of tawny selae at the 

 hind margin. Last ventral segment in the male with a deep
