outer joints as wide as long; eyes large, strongly elongate, and about 

 equally rounded above and beneath. 



Pronotum at least one-half wider than long, base slightly wider 

 than apex, and widest at middle ; sides strongly arcuately rounded ; 

 when viewed from the side the marginal carina is slightly sinuate, 

 the submarginal carina sinuate and only feebly indicated; anterior 

 margin strongly sinuate, with a broadly rounded median lobe; base 

 strongly emarginate at middle of each elytron, the median lobe 

 broadly rounded, and subtruncate in front of scutellum; disk 

 moderately convex, with a rather deep, broad, median depression 

 not quite extending to base or apex, a broad, shallow depression on 

 each side along lateral margin, and without prehumeral carinae; 

 surface closely, finely, irregularly rugose, finely, densely punctate 

 between the rugae, with a median band of densely placed yellow and 

 reddish-yellow pubescence not quite extending to base or anterior 

 margin, and a large triangular area of similar pubescence covering 

 the lateral third of pronotum. Scutellum transversely carinate, and 

 the surface densely reticulate. 



Elytra about as wide as pronotum at base, about equal in width 

 at base and apical third, deeply, broadly, arcuately constricted at 

 middle, and arcuately attenuate from apical third to the tips, 

 which are separately, broadly rounded, and finely serrulate; sides 

 of abdomen broadly exposed above; disk feebly flattened, without 

 longitudinal costae, but with broad, deep, basal depressions; surface 

 finely, densely imbricate-punctate, and not pubescent. 



Abdomen beneath finely, densely punctate, obsoletely granulose, 

 more coarsely, densely punctate, and strongly rugose on the first two 

 segments, especially on the first, and moderately clothed with short, 

 recumbent, whitish hairs; vertical portions of the segments densely 

 clothed with long, recumbent, golden-yellow pubescence; first seg- 

 ment scarcely flattened, the second segment with a narrow, obsolete 

 groove, extending from base to near the posterior margin of the seg- 

 ment ; last segment subtruncate at apex ; pygidium coarsely punctate, 

 strongly carinate, the carina projecting and truncate at apex. Pro- 

 sternum densely, coarsely punctate, coarsely rugose or scabrous, and 

 sparsely clothed with short, whitish hairs; prosternal lobe broad, 

 strongly declivous, and broadly rounded or subtruncate in front; 

 prosternal process broad, the sides parallel to behind the coxal cavi- 

 ties, without dentiform reflexion of the edge, then abruptly nar- 

 rowed to the apex, which is acute. Posterior coxae with the posterior 

 margin tranversely truncate, and the exterior angle rectangular. 

 Tibiae slender, nearly straight, and all three pairs with a feeble tooth 

 on the inner margin at apex. Posterior tarsi distinctly shorter than 

 tibiae, and the first joint about equal in length to the following three
