Male. — Form resembling egenus Gory, slightly flattened above, and 

 strongly shining; head green, with a distinct aeneo-cupreous tinge; 

 pronotum and elytra bronzy green to olivaceous green, and each 

 elytron ornamented with three more or less distinct pubescent spots ; 

 beneath bronzy green, with a slight cupreous tinge, and more shining 

 than above. 



Head with the front rather wide, feebly convex, about equal in 

 width at top and bottom, the lateral margins nearly parallel, vaguely 

 constricted near bottom, and with a broad, vague, median depression 

 on* vertex ; surface densely, finely granulose, feebly, sparsely punctate, 

 transversely rugose behind epistoma, longitudinally rugose on occi- 

 put, and sparsely clothed with short, recumbent, silvery white hairs 

 behind the epistoma; epistoma slightly transverse between the an- 

 tennae, and broadly, deeply, arcuately emarginate in front; antennae 

 extending to posterior angles of pronotum, serrate from the fifth 

 joint, and the outer joints distinctly longer than wide; eyes large, 

 broadly elongate, and slightly more acutely rounded beneath than 

 above. 



Pronotum about one-third wider than long, nearly equal in width 

 at base and apex, and widest along apical half ; sides nearly parallel 

 or vaguely, arcuately rounded from apical angles to behind middle, 

 then more strongly narrowed to the posterior angles, which are rec- 

 tangular ; when viewed from the side the marginal and submarginal 

 carinae are slightly sinuate, narrowly separated anteriorly, and con- 

 nected to each other behind the middle, anterior margin strongly 

 sinuate, and the median lobe strongly, broadly rounded; base trans- 

 versely bisinuate, with the median lobe feebly produced, and sub- 

 truncate in front of scutellum; disk moderately convex, with two 

 feeble, median depressions, a broad, shallow, oblique depression on 

 each side along lateral margin, and with sharply defined, straight, 

 prehumeral carinae, extending from posterior angles to near middle ; 

 surface finely granulose, coarsely, transversely rugose, and sparsely, 

 finely punctate between the rugae. Scutellum strongly, transversely 

 carinate, and the surface finely densely reticulate. 



Elytra slightly wider than pronotum at base, and equal in width 

 at base and behind middle ; sides nearly parallel for a short distance 

 behind base, feebly, broadly constricted in front of middle, broadly, 

 arcuately expanded behind the middle, then obliquely narrowed to the
