Male. — Form of otiosus Say, and moderately shining; antennae 

 and head green, the latter becoming aeneo-cupreous on the occiput; 

 pronotum bronzy brown on the median part, becoming bronzy greeD 

 toward the sides; elytra black, with a vague purplish reflection; 

 beneath uniformly dark bronzy green, and more shining than above. 



Head with the front wide, slightly convex, about equal in width at 

 top and bottom, the lateral margins feebly, arcuately expanded at 

 vertex, and without a median depression; surface finely, densely 

 granulose, coarsely, rather densely punctate, slightly rugose behind 

 the epistoma, feebly, longitudinally rugose on occiput, and sparsely 

 clothed on lower half with long, semierect, whitish pubescence; 

 epistoma transverse between the antennae, and feebly, broadly emar- 

 ginate in front; antennae extending slightly beyond middle of 

 pronotum, serrate from the fourth joint, and the outer joints slightly 

 longer than wide; eyes large, rather broadly oblong, and about 

 equally rounded above and beneath. 



Pronotum nearly one-half wider than long, slightly narrower at 

 base than apex, and widest near the middle ; sides nearly parallel or 

 feebly sinuate from apical angles to middle, then obliquely narrowed 

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

 the side the marginal carina is more or less sinuate, the submarginal 

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

 teriorly, and connected to each other at base; anterior margin 

 strongly sinuate, with the median lobe broadly rounded; base trans- 

 versely bisinuate, the median lobe feebly produced, and arcuately 

 emarginate in front of scutellum; disk moderately convex, with two 

 round, more or less distinct depressions arranged longitudinally at 

 the middle, a broad, deep depression along lateral margin, extend- 

 ing from near the apex to base, and with feebly indicated prehmneral 

 carinae ; surface coarsely, densely, transversely rugose, finely, densely 

 granulose, and with numerous fine punctures between the rugae. 

 Scutellum strongly, transversely carinate, with the surface densely 

 reticulate.
