brown, reflecting pale green wherever the light falls 
upon it, moderately thickly and extremely delicately

obliquely narrowed to the front; the sides, however, very 
slightly angular ; the base with a broad arcuate lobe in 
the middle. Scutellum 2 millimetres long, and the same 
width at the base, triangular, but rounded at the apex 
itself. Elytra very little enlarged posteriorly, subparallel, 
deflexed at the apex, not very thickly and scarcely visibly 
punctured even with a glass ; the extreme apex rugulose ; 
the apical callosity rather prominent and conical; the 
margin at the shoulder is thickened, along the rest of the
