Male. — Form small, moderately elongate, slightly flattened above, 

 and feebly shining; head varying from bluish green to bronzy green, 

 becoming piceous on the occiput; pronotum and elytra piceous, 

 sometimes with a feeble cupreous tinge, and each elytron orna- 

 mented with a more or less distinct pubescent vitta extending from 

 basal depression to apex; beneath piceous, with a bronzy 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 vaguely, arcuately 

 constricted below the middle, and with a feeble, narrow, longitudinal 

 groove extending from the occiput to the epistoma; surface densely, 

 finely granulose, rather densely, finely punctate, becoming longi- 

 tudinally rugose on the occiput, and sparsely, uniformly clothed with 

 moderately long, recumbent, silvery white hairs ; epistoma not trans- 

 verse between the antennae, and broadly, not deeply, arcuately 

 emarginate in front; antennae extending to middle of pronotum, 

 serrate from the fifth joint, and the outer joints about as wide as 

 long; eyes large, and equally rounded above and beneath. 



Pronotum about one-fourth wider than long, slightly narrower at 

 base than apex, and widest near the middle; sides feebly, arcuately 

 rounded from apical angles to behind the middle, then more strongly 

 narrowed to near the base, where they are parallel, with the posterior 

 angles rectangular or feebly produced outward ; when viewed from 

 the side the marginal carina is feebly sinuate, the submarginal carina 

 nearly straight, the two carinae rather widely separated anteriorly, 

 and connected to each other behind the middle; anterior margin 

 feebly sinuate, and the median lobe not prominent : base feebly 

 emarginate at middle of each elytron, and the median lobe feebly, 

 broadly rounded; disk moderately convex, with a more or less dis-
