golden yellow pubescence in the lateral and anterior median depres- 

 sions. Scutellum strongly, transversely carinate, and the surface 

 finely reticulate. 



Elytra slightly wider than pronotum at base, and equal in width 

 at base and behind middle ; sides nearly parallel for a short distance 

 behind base, broadly, arcuately constricted in front of middle, 

 broadly, arcuately expanded behind the middle, then obliquely nar- 

 rowed to the tips, which are separately, rather narrowly rounded, 

 and strongly serrulate ; disk feebly, broadly depressed along sutural 

 margins, causing a more or less distinct longitudinal costa at middle 

 of each elytron, sutural margins distinctly elevated toward apex, and 

 with broad, moderately deep basal depressions; surface finely, 

 densely imbricate-punctate, sparsely clothed with short inconspicu- 

 ous hairs, and each elytron ornamented with a broad, yellowish white 

 pubscent vitta extending along the sutural depression from the basal 

 depression to near apex. 



Abdomen beneath obsoletely reticulate, finely, rather densely punc- 

 tate, the punctures more or less connected transversely by sinua^ 

 lines at sides of segments, sparsely clothed with short inconspicuous 

 hairs at middle, but more densely clothed with longer hairs at the 

 sides ; sides narrowly exposed above ; first segment convex and with- 

 out long hairs at middle; last segment broadly rounded at apex; 

 suture between first and second segments indicated at the sides ; ver- 

 tical portions of the segments nearly glabrous; pygidium longitudi- 

 nally carinate, but the carina not projecting at apex. Prosternum 

 sparsely, finely punctate, somewhat rugose, and sparsely clothed with 

 short recumbent hairs; prosternal lobe broad, moderately declivous, 

 and broadly rounded in front; prosternal process broad, the sides 

 parallel to behind the coxal cavities, then obliquely narrowed to the 

 apex, which is acute. Tibiae slender, straight, and without a distinct 

 tooth on inner margin at apex. Posterior tarsi about one-half as 

 long as the tibiae, and the first joint subequal in length to the follow- 

 ing joints united. Tarsal claws similar on all feet, cleft near the 

 middle, the inner tooth broader and much shorter than outer one 

 and not turned inward.
