tured ; rostrum very short, strongly transverse ; at the base of each 

 antenna there is a slight round tumour ; mandibles pitchy. Thorax 

 shining, clothed vrith very delicate grey pubescence, only visible in 

 some lights. Elytra densely pubescent ; each elytron with three 

 distinct roof-like costae, and with an indication of a fourth. 



(S . Antennae nearly as long as the elytra ; third joint a little 

 elongate, very obliquely truncate at the apex ; fourth joint as long 

 as the two preceding taken together, compressed, broader than the 

 third ; the fifth to tenth the same length as the third, the eighth, 

 ninth, and tenth diminishing in width, the fifth to eighth with the 

 lower anterior angle a little produced, the eleventh joint a little 

 longer and much narrower than the preceding. Thorax subquad- 

 rate, rather straight at the sides, arched in front, with a deep mesial 

 longitudinal channel, and on each side two deep fovese, the raised 

 portion dividing the fovese obli(|ue. Penultimate segment of the 

 abdomen triangularly emarginate at the apex, and with a deep lon- 

 gitudinal mesial channel. 



5 . Antennae two thirds the length of the elytra ; third joint as 

 broad at its apex as long, fourth to ninth scarcely longer than 

 broad, the tenth a little narrower, eleventh narrowed at the apex. 

 Thorax a little broader than long, rather narrowed in front. The 

 rest as in the male.

Head gently convex, impressed on the forehead ; rostrum ex- 

 tremely short, the space between the antennal pit and the base of the 

 mandible about half the diameter of the antennal pit. Antennae 

 about two thirds the length of the elytra and (for the genus) rather 

 slender ; the sixth to tenth joints slightly diminishing in length and 

 a trifle more slender ; eleventh joint a little longer, parallel, scarcely 

 acuminate at the apex. Thorax black, margined, delicately pubes- 

 cent ; disk transversely impressed behind the middle, deeply im- 

 pressed in front of and behind the oblique lateral ridge. Penultimate 

 segment of the abdomen with a deep incision.
