impressed ou the inner disk witli fine irregular reticulating 

 strigfe ; on the outer disk and at the apex the interspaces arc 

 thickened and form coarse irregular transverse rugic. The general 

 colour of the elytra is rufo-igueous ; but on their dorsal surface is 

 a common, broad, ill-defined, bright metallic green band, which 

 extends from the base nearly to the apex of the elytra, the punc- 

 tures on its surface, together with a very narrow sutural line, 

 metallic purple.

Head granulose, vertex rugulose, coarsely but not very closely 

 punctured, sparingly clothed with adpressed white, scale-like, 

 hairs; clypeus not longer than broad, trigonate, its apex de- 

 pressed, not distinctly separated from the face ; the sides rounded, 

 the anterior margin transversely truncate, armed with two very 

 short obtuse teeth ; jaws nigro-piceous ; antenna) nearly equal to 

 the body in length, robust, attenuated towards the apex, the basal 

 joint strongly thickened, subglobose, the second short, about half 

 the length of the first, slightly thickened, the third to the seventh 

 equal in length, each as long as the first two united, the third to 

 the eleventh moderately compressed ; eyes elongate-ovate, sinuate 

 within. Thorax scarcely broader than long ; sides nearly parallel, 

 slightly converging from base to apex, slightly bisinuate, the an- 

 terior angle excurved ; above subcylindrical, sparingly clothed 

 with adpressed scale-like hairs, coarsely but not deeply rugulose- 

 punctate, the middle disk with a broad, shallow, ill-defined longi- 

 gitudinal depression, which extends from the base nearly to the 

 apex. Scutellum semiovate, its apex subacute. Elytra broader 

 than the thorax, subelongate, the sides parallel ; above convex, 

 coarsely but not very deeply rugulose-punctate ; each elytron with 

 three or four ill-defined vittse, the one on the middle disk and 

 another below the humeral callus more distinct than the others.
