rior angle, and a broader and much deeper depression along the lat- 

 eral margins near middle, the lateral carina not distinct, and repre- 

 sented by an obsolete arcuate elevation, coarsely, densely, and irreg- 

 ularly rugose, and finely and rather densely punctate between the 

 rugae. Scutellum transversely carinate, the carina broadly rounded 

 on top: sides parallel anteriorly, and strongly arcuately attenuate 

 posteriorly to the apex, which is acute; surface finely and densely 

 gran u lose. 



Elytra slightly wider than pronotum at base, and four times as 

 long as it; sides parallel for a short distance behind the base, broadly 

 arcuately constricted in front of middle, broadly arcuately rounded 

 behind the middle, then arcuately attenuate to the tips, which are 

 separately narrowly rounded and obsoletely dentate; disk moderately 

 convex, and each elytron with a broad basal depression, which is 

 deep at the basal margin, but becoming more shallow posteriorly and 

 extending behind the tip of the scutellum, and with a broad obsolete 

 longitudinal depression behind the middle along the suture, which 

 is rather strongly elevated posteriorly; surface coarsely and densely 

 imbricate-punctate. 



Abdomen with the sides broadly exposed above, and beneath 

 sparsely but not deeply punctate, the punctures very coarse and more 

 or less confluent at base of first segment, but becoming finer and more 

 widely separated toward apex, sparsely clothed with short inconspic- 

 uous hairs, and the intervals finely, densely granulose; first segment 

 convex at middle, and without any median depression ; last segment 

 narrowly rounded at apex, with a small angular emargination at the 

 middle; pygidium with a distinct median carina, which does not extend 

 to apex. Prosternum coarsely scabrous, with the intervals finely 

 granulose and glabrous; prosternal lobe large, broadly rounded in 

 front, deeply and broadly arcuately emarginate at the middle, and 

 strongly declivous; prosternal process longitudinally concave, the 

 sides parallel to behind the coxal cavities, then strongly attenuate to 

 the tip, which is rather acute. Femora flattened and not armed 

 with teeth on the inner margin. Tibiae slender, straight and not 

 mucronate at apex. Posterior tarsi much shorter than the tibiae, 

 and the first joint about as long as the following two joints united. 

 Tarsal claws cleft at middle, the inner tooth about one-half as long 

 as the outer tooth, and not turned inward (claws on middle tarsi 

 missing).
