Male. — Form moderately elongate, subcylindrical, not strongly 

 narrowed posteriorly, feebly flattened above, and feebly shining; 

 head and pronotum bronzy brown, with a feeble cupreous reflect- 

 tion; elytra aeneous, slightly purplish, and more cupreous near 

 base; beneath brownish black anteriorly, strongly bronzy green on 

 abdomen, and the legs more or less cupreous. 



Head with the front rather wide, distinctly wider at top than at 

 bottom, the lateral margins obliquely expanded from bottom to 

 top, and with a deep, triangular depression on the front with its 

 base along the epistoma, and a narrow, longitudinal groove extend- 

 ing from the depression to occiput; surface coarsely, densely punc- 

 tate, the punctures more or less confluent, and sparsely clothed with 

 long, recumbent, yellowish white hairs; epistoma not transverse be- 

 tween the antennae, strongly elevated, and broadly, deeply, arcuately 

 emarginate in front ; antennae not extending to middle of pronotum, 

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

 long; eyes moderately large, broadly oblong, and slightly more 

 broadly rounded beneath than above. 



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

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

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

 and submarginal carinae are feebly sinuate, not sharply defined, 

 widely separated anteriorly, and connected to each other near the 

 base, where they are more or less obliterated ; anterior margin feebly 

 sinuate, and the median lobe scarcely indicated; base strongly, 

 angularly emarginate at middle of each elytron, and the median 

 lobe broadly rounded in front of scutellum; disk rather strongly 

 convex, with a broad, vague median depression extending from base 

 to apex, a broad, shallow, oblique depression on each side along 

 lateral margin at middle, and with a broadly rounded elevation re- 

 placing the prehumeral carina; surface coarsely, densely punctate, 

 the punctures more widely and irregularly separated on each side of
