punctate, with a low broad central carina (sometimes rather 

 ill-detined) and a narrower curved one on each side of it ; 

 set with iDrownish carved scale-like setae, and sometimes 

 with some narrow bluish scales ou the apical half; scrobes 

 with the upper margin sharply angulate close to the base. 

 Antenna with the scape distinctly curved, the funicle Avitli 

 joint 1 hardly longer than 2, 3-7 subequal, bead-like, and 

 slightly broader than long. Prothorax broader than long 

 (3 : 2), broadest at the base, strongly narrowed in front, the 

 sides rounded, the apical angles very prominent (as seen 

 from above), the dorsal apical margin truncate, the basal 

 margin arcuate ; the dorsal outline strongly convex trans- 

 versely and sliglitly so longitudinally, the apex being much 

 below the level of the base ; the upper surface strongly and 

 very closelj' punctate, with a faint longitudinal impression 

 in tlie middle of the base, the sculpture on the inflexed sides 

 becoming more or less plicate ; the lateral portion of the 

 apical margin cariuately raised, forming an obtuse angle 

 below the eye and a sharp projection in front of each coxa. 

 Scutellum closely punctate. Elytra narrowly elliptical and 

 broadest before the middle in ^ , rather broader in ? , which 

 has the humeral angulation scarcely perceptible, the basal 

 margin jointly sinuate; the elytra strongly compressed 

 beliind, so that the suture is elevated on the declivity, the 

 longitudinal outline almost flat in ,$ , the apical portion 

 dropping aluiost 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 strise with large quadrate 

 punctures, the intervals about as broad as the strise, finely 

 punctate and somewhat rugulose transversely, with scattered, 

 extremely minute, scale-like setse, which are conspicuous 

 only on the declivity. Sternum: raesosternum with a per- 

 fectly smooth shiny patch adjoining the outer sides of the 

 mid-coxae and standing out in contiast with the strongly 

 sculptured surface; metasternum sparsely granulate. Venter 

 vei'y rugosely punctate and granulate, especially in the (J , 

 in which the first segment bears behind the coxa a deep 

 excision, the poition between it and the elytra being smooth 

 and shiny.
