668 COLEOPTERA 



The insect exhibits characters which do not accord with those of any 

 genus known to me. The close adaptation of the elytra to the base of 

 the thorax, rounded outline, and unusual convexity are distinctive features. 



1165. C politllla, n.s. Convex, nearly round, the general cur- 

 vature of the body almost uninterrupted, quite nude above, shining black ; 

 legs and antennae more or less piceo-rufous. 



Head distinctly but not at all closely punctured, the cibarial organs 

 somewhat reddened. -Projthorax very short, very finely and remotely 

 punctulated, its lateral rims and apex rufescent. Elytra with moderate 

 shallow punctures, much larger than those of the thorax, yet not readily 

 perceptible, with rufescent margins. Antenna as long as head and 

 thorax, glossy, with a few yellowish hairs ; club pubescent. Tibice in- 

 wardly ciliated, and finely pilose. Under-side reddish-black, punctulated, 

 and pubescent. Trochanters deeply notched inwardly.

Nov. gen. 



Mandibles robust, strongly arched externally, simple. Terminal 

 joint of the palpi oviform, obtuse at apex. Antennas 1 1 - articu- 

 late, inserted at the sides just in front of the eyes, their three basal 

 joints longer than the following five: first rather longer than third, 

 stoutest, sub-pyriform ; second cylindrical, intermediate in thickness 

 between the contiguous ones, shorter than either ; third slender, a little 

 dilated towards the extremity ; fourth and fifth equal, shorter than 

 second, sub-cylindric ; sixth and seventh about equal, each shorter than 

 preceding; eighth about as long as seventh nearly twice its breadth, 

 greatly narrowed at its base. Club distinct, oblong, tri-articulate ; basal 

 joint cup-shaped ; second transversal ; third obtusely rounded, with an 

 indistinct appendage or false joint at its extremity. Head large, nearly as 

 broad as thorax, immersed up to the eyes, produced obtusely beyond the 

 antennal insertion, Eyes large, not very convex, moderately facetted. 

 Prothorax transversely quadrate, marginated laterally, sub-truncate at 

 base, sinuated in front behind the eyes, scarcely overlapping the elytra. 

 Scutellum rounded behind. Elytra oblong, obtusely rounded behind, 

 leaving the pygidium exposed. Legs robust, femora dilated; tibia? 

 gradually expanded towards the extremity, terminating in a straight 

 calcar. Tarsi with dilated basal articulations, each becoming shorter 

 than its predecessor ; second and third, cordiform ; fourth, minute ; fifth, 

 almost as long as the preceding four united. Claws large, thickened 

 though not actually dentate at the base ; soles hispid, the three basal 

 joints with a bunch of bristles at each front angle. Prastemal process 

 gradually dilated behind, finely margined, rounded at apex, resting on a 

 mesosternal impression having raised margins. Antennal grooves ex- 

 tending from the inner margin of the eyes. Metasternum moderately 

 long. Abdomen composed of five segments, the basal moderately large, 

 second and third about equal, fourth and fifth nearly equal. The coxa 

 gradually become more apart.
