Antennae filiform, the third joint one half longer than the 

 second ; pale flavous ; the terminal and occasionally the upper 

 half of the penultimate joints more or less stained with black. 

 Thorax about one fourth broader than long ; sides nearly straight 

 and diverging from the base to the middle, thence rounded and 

 converging towards the apex, the anterior angles thickened and 

 produced, obtuse, hinder angles acute ; hinder margin obtusely 

 rounded; disk convex, smooth, impunctate. Elytra oval, convex, 

 finely but not very closely punctured ; on the anterior disk of each 

 elytron in the <S (the only sex known to me) is a large, very 

 shallow and ill-defined excavation, the outer and hinder edges of 

 which are broadly but slightly thickened.
