Male. — Form moderately robust, subcylinclrical, slightly flattened 

 above, and feebly shining; head, pronotum, and elytra brownish 

 cupreous, with the sides of pronotum and vitta on each elytron 

 sparsely clothed with short, recumbent, whitish hairs; beneath 

 cupreous, and more shining than above. 



Head with the front rather wide, slightly convex, about equal in 

 width at top and bottom, the lateral margins feebly expanded near 

 the middle, and with a moderately deep, broad depression extending 

 from occiput to epistoma ; surface finely, densely granulose, sparsely 

 punctate, coarsely rugose, especially on the occiput where the rugae 

 are longitudinal, and the surface nearly concealed by long, re- 

 cumbent, whitish pubescence; epistoma slightly transverse between 

 the antennae, slightly elevated, and broadly, deeply, arcuately emar- 

 ginate in front; antennae extending to middle of pronotum, serrate 

 from the fifth joint, and the outer joints about as wide as long; eyes 

 large, broadly oblong, and about equally rounded above and beneath. 



Pronotum slightly wider than long, feebly narrower at base than 

 apex, and widest along apical half; sides nearly parallel or vaguely 

 narroAved from near apical angles to behind middle, then more 

 strongly, obliquely narrowed to the posterior angles, which are rec- 

 tangular ; when viewed from the side the marginal carina is strongly 

 sinuate, the submarginal carina feebly sinuate, the two carinae rather 

 widely separated anteriorly, and connected to each other behind the 

 middle; anterior margin strongly sinuate, and the median lobe 

 strongly rounded; base feebly emarginate at middle of each elytron, 

 the median lobe strongly, broadly rounded, and feebly emarginate in 

 front of scutellum; disk moderately convex, with a broad, shallow, 

 transverse median depression at apical third, a broad, deep, oblique 

 depression on each side along lateral margin, and with moderately 

 distinct, sinuate prehumeral carinae; surface finely, densely granu- 

 lose, strongly, closely, transversely rugose at the middle, sparsely, 

 finely punctate between the rugae, and rather densely clothed with 

 long, recumbent, whitish hairs toward the sides. Scutellum feebly, 

 transversely carinate, and the surface densely, finely reticulate. 



Elytra about as wide as pronotum at base, and slightly wider at 

 base than behind middle; sides nearly parallel for a short distance 

 behind base, broadly, arcuately constricted near middle, broadly,
