‘parallel, vaguely rounded at middle; surface nearly glabrous, densely, 
finely granulose over entire surface, th a few coarser granules inter- 
mixed; clypeus quadrate, rather “Hise between antennae, depressed 
posteriorly, shallowly, arcuately emarginate in front; antenna extend- 
ing to middle of pronotum, serrate from fourth segment. 
Pronotum slightly wider than long, subequal in width at base and 
apex, widest along apical half; sides parallel anteriorly, vaguely 
converging posteriorly; posterior angles rectangular; marginal and 
submarginal carinae straight, rather widely separated anteriorly, 
united at basal fourth; anterior margin strongly sinuate, median lobe 
strongly produced and broadly rounded; base transversely sinuate 
on each side, median lobe scarcely produced, broadly rounded in 
front of scutellum; prehumeral carinae strongly elevated, straight, 
extending obliquely inward from posterior angles to middle at some 
distance from lateral margins; disk uneven, broadly depressed along 
sides, with three broad depressions at base and an elongate, median 
depression in front of middle; surface densely, finely granulose, 
feebly, coarsely, transversely, irregularly rugose, finely, indistinctly 
punctate between rugae, sparsely clothed at sides and in basal depres- 
sions with short, recumbent, white hairs. Scutellum transversely 
carinate. 
Elytra broadly, shallowly constricted in front of middle, not dis- 
tinctly depressed along sutural margins, tips separately broadly 
rounded and finely, irregularly dentate; surface rather coarsely, 
densely imbricate-punctate, each elytron clothed with short, recum- 
bent, white pubescence as follows: A large spot in basal depression, 
an elongate spot in front of middle, the spot deeply emarginate ex- 
ternally, and nearly separated into two spots, a large triangular spot 
at apical third, and a few inconspicuous hairs at apex. 
Abdomen scarcely exposed above, strongly convex beneath; surface 
finely, sparsely punctate, with fine, undulating lines, sparsely clothed 
with very short, inconspicuous hairs, a spot of erect hairs at middle 
of first sternite, and a spot of dense, recumbent, white hairs at sides 
of third sternite; suture obsolete between first and second visible © 
sternites; vertical portions of sternites not conspicuously pubescent; — 
posterior coxae densely clothed with recumbent, white hairs. Pro-— 
sternum finely, densely granulose, densely clothed with long, erect 
hairs; prosternal lobe shallowly, arcuately emarginate in front; — 
prosternal process broad, sides obliquely converging posteriorly to 
the obtuse tooth at apex, not expanded behind coxal cavities. Tarsal | 
claws similar on all feet, cleft near middle, inner tooth of each very 
short and not turned inward. 
Female.—Differs from the male in having the front of head cupre- | 
ous, and in not having long, erect hairs on the prosternum and first | 
abdoreinal sternite.
