rax convex, sides rounded anteriorly, narrowed posteriorly ; posterior 

 angles rather long, divergent, carinated. the apex obtuse ; disk 

 with an obsoletely impressed line, more obvious in front ; posterior 

 margin deeply impressed ; scutellum round, depressed, with a slight 

 grey pubescence. Elytra about as wide as the thorax, depressed at 

 base and slightly narrowed, widest at the posterior third and then gi-a- 

 dually attenuated to the apex; striae well impressed, very deeply so at 

 base, rather indistinctly punctured, interstices convex, finely punc- 

 tured ; beneath black, polished, minutely punctuted, slightly pubescent. 

 Legs dark brown, pubescent. Length S 6 lines, 9 "> hiies. 



The female is much more robust than the male, the elytra has a 

 slight cupreous tinge, while that of the male is slightly bluish. The 

 female specimen before me also differs from the male in the general 

 color being somewhat brownish, which is doubtless owing to immaturity.
