margin almost straight from the middle to the side, anterior angles 

 rounded, posterior almost right angles ; upper surface smooth, 

 distinctly but sparingly punctate on the disc, the punctures being 

 irregularly crowded ; they are deeper, more numerous and in some 

 cases confluent on the lateral area, but they do not reach the 

 margin, thus leaving an impunctate, narrow, longitudinal strip, with 

 hardly any longitudinal depression along its inner side. Scutellum 

 semi-ovate, smooth and impunctate. Elytra slightly broader than 

 the prothorax, their sides nearly parallel, front margin rounded ; 

 surface of each elytron covered with rows of deeply impressed 

 punctures, but on the posterior half many of the rows are obsolete ; 

 a short scutellar row, a sutural row and the usual double rows are 

 present; punctures in the rows are irregular, the interspaces

remotely and very finely punctate. This species varies in the 

 amount and also in the depth of the punctuation of its surface. 

 Underside very sparsely covered with fine punctures, each bearing 

 a small silvery hair.
