Length 3 !/, lines. 
Head impunctate; antennae black, the extreme apex of the 
. terminal joint obscure fulvous, the fourth joint nearly twice as 
long as the preceding; thorax with the sides and the posterior 
margin rounded, the anterior angles slightly thickened, surface 
remotely and very finely punctured, rather depressed near the 
middle of the base; scutellum piceous; elytra oblong, the 
shoulders rounded, very finely and closely punctured black, the 
base to the extend of the first third of their length as well as
