Male. — Form rather slender, subcylindrical, moderately shining,, 

 and feebly flattened above, color varying from olive green, with a 

 more or less cupreous reflection, to a dark brown, with a distinct 

 cupreous tinge; beneath cupreous brown to dark bronzy green, and 

 more shining than above. 



Head with the front rather wide, nearly flat, about equal in width 

 at top and bottom, without distinct depressions, lateral margins 

 feebly, arcuately expanded at middle, and with a narrow, longitu- 

 dinal groove extending from occiput to middle of front; surface 

 densely, coarsely punctate, the punctures more or less confluent, some- 

 times becoming rugose on occiput and in front of epistoma, and 

 sparsely clothed with moderately long, semierect, cinerous hairs; 

 epistoma wide between the antennae, and broadly, deeply, arcuately 

 emarginate in front ; antennae extending bej^ond middle of pronotum, 

 serrate from the fourth joint, and the outer joints feebly longer than 

 wide ; eyes large, and about equally rounded above and beneath. 



Pronotum not quite one-half wider than long, base and apex about 

 equal in width and widest at middle ; sides rather strongly arcuately 

 rounded ; when view T ed from the side the marginal carina is strongly 

 sinuate, the submarginal carina feebly sinuate, the two carinae not 

 very widely separated anteriorly, and connected to each other at the 

 base ; anterior margin rather strongly sinuate, with a broadly rounded 

 median lobe ; base slightly emarginate at middle of each elytron, the 

 median lobe broadly rounded, and subtruncate in front of scutellum ; 

 disk moderately convex, depressions variable, and with a distinct, 

 arcuate prehumeral carina extending from base near posterior angles 

 to basal third; surface densely, coarsely, transversely rugose, finely 

 punctate between the rugae, and sparsely clothed with short, incon- 

 spicuous hairs. Scutellum transversely carinate, and the surface 

 finely reticulate. 



Elytra slightly wider than pronotum at base and about equal in 

 width at base and apical third ; sides nearly parallel for a short dis- 

 tance behind the base, slightly, broadly, arcuately constricted in front
