outer margin which is very rugose and has a white pubescence ; the 

 elytra are as broad as the prothorax, slightly ampliated past the 

 shoulder, narrowed past the first third of the length, and from there 

 tapering gradually towards the apex, not much convex, finely striato- 

 punctated with narrow punctures on the intervals ; underside olive- 

 green, very shining, with a thick yellow pubescence on the sides, 

 roughly foveated with the foveas white and slightly pilose ; legs very 

 rugose. 



Allied to the preceding species ; the facies is nearly the same, but 

 the size is constantly smaller, the colouring of the underside is not the 

 same, and the lateral patches of the prothorax are shaped and coloured 

 differently.
