 distinctly punctured, impressed near the hinder angle with a 

 deep fovea. Elytra oblong, sides narrovi^ed and rounded at the 

 apex, the latter dehiscent; surface distinctly punctured, the 

 apex and a broad transverse band in front black; the latter, 

 which is abbreviated close to the outer border, extends from just 

 below the basal margin to the middle of each elytron, its posterior 

 border being oblique, and forming a more or less obtuse angle 

 at the suture. Beneath pale fulvous, covered with coarse con- 

 colorous hairs ; hinder thighs incrassate, their outer surface (the 

 extreme base excepted) shining black ; a patch on the pleurse, a 

 spot on the upper and under surfaces of the intermediate femora, 

 and the outer surface of the four anterior tibise, nigro-piceous.

Subelongate, subdepressed ; above fulvous. Head distinctly

 above transversely convex, finely but not closely punctured, im- 

 pressed near the hinder angle with a deep fovea; fulvous, a 

 large transverse patch on the disk, bilobate behind, black ; sur- 

 face of the thorax surrounding this patch more or less stained

 angle, an oblique vitta extending from the scutellum nearly to
