Male. — Form rather large, strongly flattened above, strongly shin- 

 ing, and uniformly aeneous, with a strong reddish cupreous or vio- 

 laceous tinge; beneath reddish cupreous, and more shining than 

 above. 



Head with the front rather wide, nearly flat, about equal in width 

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

 near middle, and with a feeble longitudinal groove extending from 

 occiput to middle of front; surface coarsely punctate, more or less 

 longitudinally rugose on the occiput, and the surface nearly concealed 

 by the long, recumbent, yellowish white pubescence and efflorescence ; 

 epistoma strongly transverse between the antennae, strongly ele- 

 vated, and broadly, deeply, arcuately emarginate in front; antennae 

 extending to about middle of pronotum, serrate from the fourth joint, 

 and the outer serrate joints as wide as long; eyes large, elongate, and 

 about equally rounded beneath and above. 



Pronotum nearly one-half wider than long, base and apex about 

 equal in width, and widest at middle; sides feebly, arcuately rounded, 

 and slightly sinuate near posterior angles, which are rectangular; 

 when viewed from the side the marginal and submarginal carinae are 

 slightly sinuate, very narrowly separated, and connected to each 

 other at base; anterior margin slightly sinuate with a broadly 

 rounded median lobe; base feebly emarginate at middle of each 

 elytron, and the median lobe feebly, broadly rounded; disk moder- 

 ately convex, with a vague, longitudinal median depression, which 

 is more broadly depressed in front of scutellum, a broad, shallow 

 depression on each side along lateral margin, and with obtusely 

 rounded, arcuate, prehumeral carinae, extending from base to near 

 middle of pronotum; surface coarsely, transversely rugose at middle, 

 sparsely, coarsely punctate between the rugae, and sparsely clothed 

 with short, inconspicuous hairs at the middle, but the surface at 

 sides concealed by long, recumbent, yellowish white pubescence and
