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

 rather strongly shining; head light green in front, and becoming 

 brownish cupreous on the occiput; pronotum and elytra dark bronzy 

 brown, with a more or less distinct cupreous tinge, and the elytra 

 ornamented with pubescent designs; beneath brownish cupreous, the 

 legs slightly greenish, and scarcely more shining than above. 



Head with the front rather wide, feebly convex, slightly wider at 

 bottom than at top, the lateral margins feebly narrowed from bottom 

 to top, and with a feeble, broad, longitudinal depression extending 

 from occiput to epistoma, the depression broader behind the epis- 

 toma; surface sparsely, coarsely punctate, coarsely rugose, the rugae 

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

 sparsely clothed with long, recumbent, whitish hairs; epistoma 

 strongly transverse between the antennae, and broadly but not very 

 deeply, arcuately emarginate in front; antennae extending beyond 

 middle of pronotum, serrate from the fifth joint, and the outer joints 

 about as long as wide; eyes moderately large, elongate, and more 

 acutely rounded beneath than above. 



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

 base and apex, and widest at middle ; sides feebly, arcuately rounded 

 from apical angles to behind middle, then more strongly narrowed 

 to the posterior angles, which are rectangular; when viewed from 

 the side the marginal carina is slightly sinuate, the submarginal 

 carina nearly straight, the two carinae rather widely separated an- 

 teriorly, and connected to each other near the middle; anterior 

 margin strongly sinuate, and the median lobe broadly, strongly 

 rounded; base slightly emarginate at middle of each elytron, the 

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

 disk moderately convex, with two broad, deep median depressions, 

 feebly connected by a narrow groove, a broad, moderately deep, 

 oblique depression on each side along lateral margin, and with dis- 

 tinct, long, prehumeral carinae; surface coarsely but not closely, 

 transversely rugose, finely, sparsely punctate between the rugae, and 

 sparsely clothed with short, recumbent, white hairs. Scutellum 

 strongly, transversely carinate, and the surface finely, densely 

 reticulate. 



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

 width at base and behind the middle; sides nearly parallel for a 

 short distance behind base, feebly, broadly constricted in front of
