c? . Dark brown, varying to reddish brown on the elytra, except 

 at the suture and outer margins which are almost black ; 

 pronotum with four widely separated 

 yellowisli pubescent spots, two near the 

 base and two near the apex. Antennae 

 reach to the apex of the elytra or 

 a little beyond ; joints third to fifth 

 thickened and strongly scabrous ; third 

 somewhat canaliculate behind, three times 

 as long as the first and equal in length to 

 the fourth and fifth united, these two 

 together being as long as the next five. 

 Prothorax widest at the base with a 

 slightly projecting angle on each side, 

 narrowed in front ; its lateral edges dis- 

 tinct only from the base to the outer 

 angles of the coxal cavities. Elytra naked, 

 finely and ^ery closely granulate and 

 opaque ; each with two or three verv 

 feebly raised lines and either unarmed at 

 the apex or with a very short sutural spine. Last ventral segment 

 with a deep arcuate emargination behind.
