another near the base, close to the basal margin there is a transverse 

 linear depression, its punctation is irregular and rather coarse. Scutel- 

 lum small. Elytra oblong, much broader than thorax, the shoulders 

 rounded but not at all elevated, sutural striae distinct, their relatively 

 coarse punctures are nearly quite seriate, but become finer behind. 



Legs pubescent; anterior tibiae slightly bent near the extremity; 

 tarsi slender, terminal joint quite as long as the basal two united. 



Our nearest species, C. terricola (2784), has a rather shorter, sub- 

 ovate hind-body, with distinctly raised shoulders.

Oval, moderately convex, glabrous, subopaque, head and thorax 

 slightly shining; nigrescent, the legs and basal joints of antennae piceo- 

 rufous, the terminal six joints infuscate. 



Head distinctly and moderately closely punctured, the labrum rather 

 more coarsely. Thorax more than twice as broad as it is long, the sides 

 gradually narrowed anteriorly, with their margins slightly thickened 

 near the base, the apex finely margined behind the eyes, posterior angles 

 rather more acute than the anterior; its punctation is just a little finer 

 than that of the head. Scutellum triangular. Elytra of the same width 

 as thorax at the base, somewhat broader near the middle, a good deal 

 narrowed behind, their margins very distinct at the shoulders; along the 

 middle of the disc the punctures are evidently finer than those on the 

 thorax, they become even finer towards the sides, and on the hind slope 

 the sculpture is finely coriaceous; on each elytron, near the suture, 3 

 irregular series of coarser punctures extend to beyond the middle, and 

 between these and the side 4 or 5 irregular indefinite striae may be seen; 

 none of these reach the base, which is more finely sculptured than the 

 dorsum. 



Antennae elongate, joints 6-11 broader than the preceding four and 

 distinctly pubescent, the 4th joint as long as the 5th. Tibiae very 

 scantily and finely setose, the anterior grooved along their outer face, 

 the intermediate less strongly curved externally than those of P. lewisi 

 (2794), and tapering more towards the extremity. The membranous 

 appendage of the 3rd tarsal joint is prolonged under the 4th. 



Underside slightly nitid, black, with very scanty, fine, ashy pubescence. 

 Metasternum moderately coarsely punctured; the prosternal process 

 rather broad, and, like the mesosternum, finely punctate. Trochanteral 

 portion of the posterior coxal laminae rather longer than in 2794. 

 Abdomen finely punctured, the 5th segment slightly convex and nearly 

 smooth in the middle, with a feeble transverse impression behind. 



The dull elytra, with only very faintly viridescent sides, and cessa- 

 tion of perceptible punctures towards the posterior portion, will enable 

 entomologists to separate this species from 2794, which is altogether 

 more glossy and aeneous, rather smaller, with the 4th antenna! joint 

 shorter than those next to it. The underside also differs, the 5th ventral 

 segment being shorter, with distinct yellow hairs and an apical fovea.
