the posterior angles arcuately forward to the middle, where it is 

 joined to the lateral margin; surface coarsely and densely rugous, 

 the rugae more or less transverse on the disk, but becoming more 

 irregular toward the sides, sparsely, finely punctate, and sparsely 

 clothed with cinereous hairs in the depressed areas. Scutellum 

 strongly, transversely carinate, and strongly acuminate at apex; 

 surface finely and obsoletely reticulate. Elytra slightly wider than 

 pronotum at base, feebly expanded behind the humeral angles, 

 broadly constricted at middle, feebly arcuately expanded behind 

 middle, then obliquely attenuate to near the tips, which are feebly 

 expanded, subtruncate, coarsely serrate, and with a long, acute 

 spine at the middle of each elytron; sides of abdomen broadly ex- 

 posed above; disk feebly convex, and each elytron with an obsolete 

 costa at middle, causing a rather deep concave depression along the 

 suture, which is feebly elevated posteriorly; basal depressions broad 

 and deep ; surface shining, rather coarsely and obsoletely imbricate- 

 punctate. and sparsel}^ clothed with very short, inconspicuous hairs. 

 Abdomen beneath finely and ratlier densely punctate, becoming ir- 

 regularly striolate toward the sides, sparsely clothed with very 

 short cinereous hairs, and with a large densely pubescent triangular 

 spot on each side of the third segment; intervals densely and finely 

 granulose; first segment with a small round depression at middle; 

 last segment broadly rounded at apex ; vertical portion of third seg- 

 ment densely clothed with recumbent cinereous pubescence; pygi- 

 dium without a median carina at apex. Prosternum feebly, irregu- 

 larly striolate, finely and sparsely punctate, and sparsely clothed 

 with short, inconspicuous hairs; prosternal lobe broadly rounded in 

 front, broadly arcuately emarginate at middle, and strongly decli- 

 vous; prosternal process rather broad, sides feebly arcuately emar- 

 ginate to behind the coxal cavities, where they are expanded, then 

 abruptly narrowed to the apex, which is acute ; sides of prosternum, 

 metasternum and mesosternum more densely clothed with recumbent 

 cinereous pubescence than rest of body. Hind tarsi three-fourths as 

 long as tibiae, the first joint as long as the following three joints 

 united. Anterior and middle tibiae slender, feebly arcuate, and 

 subcylindrical, and more or less mucronate at the apex; posterior 

 pair straight, strongly flattened, and with a series of stiff hairs on 

 the outer margin. Tarsal claws similar on all feet, deeply cleft, 

 the teeth about equal in width, the inner one slightly shorter than 

 •the outer one, and slightly turned inward.
