 inconspicuous ; elytra but little longer than wide, obtusely rounded at apex, very 

 finely, rather feebly, evenly but not closely punctured, the pubescence rather 

 short and fine, not very conspicuous ; legs rufo-piceous ; ventral plates approach-

 arcuate ; elytra distinctly longer than wide, rather finely but strongly, evenly and 

 not closely punctate, the pubescence moderately long, cinereous and distinct ;
