 ously punctured, naked and rather glossy. Head slightly impressed on each side between the eyes; 

 palpi pale rufous, last joint dusky at the tip ; antenna? rufous with a black knob : sides of the pro- 

 thorax with two or three groups of larger punctures : elytra furrowed with thickly punctured fur-
