Male. — Form small, rather slender and moderately flattened above ; 

 head green in front, becoming more cupreous on occiput; pronotum 

 and elytra olivaceous bronze, with a more or less distinct cupreous 

 tinge; beneath slightly more shining than above. 



Head with the front rather wide, feebly convex, distinctly wider 

 at top than bottom, lateral margins nearly parallel from top to middle, 

 then strongly, obliquely narrowed to the bottom, and with a feeble, 

 longitudinal groove extending from the occiput to vertex; surface 

 densely, coarsely punctate, coarsely rugose, the rugae confused on 

 the front, but becoming longitudinal on the occiput, and clothed 

 with a few inconspicuous hairs; epistoma transverse between the 

 antennae, and broadly, deeply emarginate in front ; antennae extend- 

 ing to about middle of pronotum, serrate from the fourth joint, and 

 the outer joints distinctly wider than long; eyes rather large, rather 

 broadly oblong, and about equally rounded above and beneath. 



Pronotum one-half wider than long, about equal in width at base 

 and apex, and widest near apical fourth; sides obliquely or feebly, 

 arcuately expanded from base to apical fourth, then arcuately nar- 

 rowed to the apical angles; when viewed from the side the marginal 

 carina is slightly sinuate, the submarginal one nearly straight, the 

 two carinae widely separated anteriorly, and connected to each other 

 near the base; anterior margin feebly sinuate, and the median lobe 

 scarcely developed; base slightly emarginate at the middle of each 

 elytron, the median lobe broadly rounded, and subtruncate in front of
