Male. — Form small, rather robust, strongly flattened above, and 

 rather strongly shining ; head bright bronzy green in front, becoming 

 brownish cupreous on the occiput ; pronotum and elytra piceous, with 

 a strong aeneous or cupreous tinge, and the latter sometimes feebly 

 violaceous posteriorly, and ornamented with pubescent designs; 

 beneath similar to above, but slightly more shining. 



Head with the front rather narrow, slightly convex, and wider 

 at top than at bottom, the lateral margins feebly, broadly, arcuately 

 constricted, and with a rather narrow, longitudinal depression 

 extending from occiput to epistoma, the groove more deeply de- 

 pressed on the front, and becoming triangular behind the epistoma 

 surface obsoletely granulose, sparsely, coarsely punctate, coarsely, 

 irregularly rugose, and sparsely clothed anteriorly with moderately 

 long, recumbent white pubescence; epistoma scarcely transverse be- 

 tween the antennae, strongly elevated, and vaguely, 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 moderately large, broadly oval, and equally rounded above 

 and beneath. • 



Pronotum wider than long, about equal in width at base and apex, 

 and widest near middle; sides nearly parallel or arcuately rounded 

 from apical angles to basal third, then narrowed to the posterior 

 angles, which are rectangular; when viewed from the side the mar- 

 ginal and submarginal carinae are nearly straight or feebly sinuate, 

 rather widely separated anteriorly, and connected to each other at 

 base; anterior margin feebly sinuate, and the median lobe feebly, 

 broadly rounded ; base feebly, broadly emarginate at middle of each 

 elytron, and the median lobe broadly, vaguely rounded; disk mod- 

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

 the lateral depressions broad, deep, and extending to base, sides 

 explanate posteriorly, and without any trace of prehumeral carinae; 

 surface obsoletely granulose, coarsely but not deeply rugose, the
