oblique depression at a little distance from the anterior angles, 

 surface distantly but distinctly punctate ; scutellum smooth, metallic 

 green. Elytra scarcely wider at the base than the thorax, evenly 

 rounded towards the apex, finely punctate-striate, the interstices 

 plane ; the entire lateral margin, with the apex to a greater extent, 

 is of a bright, shining, metallic green, while the rest of the surface 

 is of a light fulvous colour, where the punctures are also surrounded 

 by a piceous spot. Underside (with the exception of the thorax and 

 part of the breast) and legs entirely fulvous.

 each elytron with three fulvous spots ; head greenish black, spa- 

 ringly but distinctly punctured, the punctures on the clypeus more 

 strongly marked ; antennae black, with the underside of the first

 closely so towards the sides ; scutellum triangular, smooth ; elytra 

 much wider than the base of the thorax, convex till their middle,

 the same way as the thorax, and partly arranged in double lines of 

 striae, each elytron with an oval patch near the scutellum, a trans-
