Head rugose, channelled between the eyes. Thorax 

 slightly produced in the middle, and at the angles of the 

 anterior margin, which is a little more than half as wide 

 as the base ; sides rounded, base nearly straight ; surface 

 rugose, especially at the sides, dorsal line wide, and 

 slightly but irregularly raised. Elytra wider than the 

 thorax, lateral margin below the shoulder with a sharp 

 angle, thence almost straight to about the middle, from 

 which it gradually curves to the apex, which is sharply 

 pointed, posterior margin denticulate; surface finely 

 rugose, the rugosities appearing to be arranged in lines ; 

 a slight depression at the base, a large round fovea on 

 the disc above the middle, a smaller one midway between 

 it and the apex, and a longitudinal impressed streak on 

 the posterior margin, pubescent and yellow. Beneath 

 rugose, the impressed portions covered with yellow 

 pubescence ; legs punctured.

 triangular dorsal line, wide at the base, where it is met
