punctate, with a low broad central carina (sometimes rather 
ill-defined) and a narrower curved one on each side of it; 
set with brownish curved scale-like sete, and sometimes 
with some narrow bluish scales on the apical half; scrobes 
with the upper margin sharply angulate close to the base. 
Antenne with the scape distinctly curved, the funicle with 
joint 1 hardly longer than 2, 38-7 subequal, bead-like, and 
slightly bro ader than long. Py othorax broader than long 
(38:2), broadest at the base, strongly narrowed iu front, the 
sides rounded, the apical aneles very prominent (as seen 
from above), the dorsal apical margin truncate, the basal 
margin arcuate; the dorsal outline strongly convex trans- 
versely and slightly so longitudinally, the apex being much 
below the level of the base; the upper surface strongly and 
very closely mune with a faint longitudinal impression 
in the middle of the base, the sculpture on the inflexed sides 
becoming more or less plicate ; ; the lateral portion of the 
apical margin carinately raised, forming an obtuse angle 
below the eye and a sharp projection in front of each coxa, 
Scutellum closely punctate. lytra narrowly elliptical and 
broadest before the middie in ¢, rather broader in 9, which 
has the humeral angulation scarcely perceptible, the basal 
margin jointly sinuate; the elytra strongly compressed 
behind, so that the suture is elevated on the declivity, the 
longitudinal outline almost flat in ¢, the apical portion 
dropping almost at a right angle and sinuate in profile; in 
the ¢ the outline slopes more from the middle to the top 
of the declivity; the shallow striz with large quadrate 
punctures, the intervals about as broad as the strie, finely 
punctate and somewhat rugulose transversely, with scattered, 
extremely minute, scale-like sete, which are conspicuous 
only on the declivity. Sternum: mesosternum with a per- 
fectly smooth shiny patch adjoining the outer sides of the 
mid-coxee and standing out in contrast with the strongly 
sculptured surface; metasternum sparsely granulate. Venter 
very rugosely punctate and granulate, especially in the ¢, 
in which the first segment bears bebind the coxa a deep 
excision, the portion between it and the elytra being smooth 
and shiny.
