b. — Thorax finely punctured, elytra parallel-sided... 



C. elongata, Gryll. 



III. — Elytra with rows of short erect bristles, parallel-sided and cylindrical... 



C. umbiUcata, Beck. 



C. linearis, Payk. 



Bather elongate, slightly convex and shining, and very finely pubescent; pitehy 

 black or dark brown, with the shoulders of the elytra often lighter, antenna and 

 legs rust-red, club of the former generally brownish; head with very short and 

 obsolete temples ; antennae with 5th and 6th joints a little longer than broad, 7th 

 and 8th globose, the first two joints of the club as long as broad ; thorax much 

 narrower than elytra, as long as broad or slightly bi'oader than long, somewhat 

 strongly and closely punctured, sides evenly rounded and obsoletely serrate, base 

 with a deep round fovea ; elytra oblong, rather depressed, broadest at the middle, 

 shoulders somewhat callose and prominent, rather strongly punctured in rows, inter- 

 stices much more finely punctured ; male with the anterior tibise feebly sinuate on 

 inner side near the apex, and the fifth ventral segment of the abdomen slightly 

 impressed. L. 1/8 — 2 mm. 



Easily distinguished from C. serrata by its proportionately nar- 

 rower thorax, with the sides much less strongly serrate, and its more 

 depressed and more parallel-sided elytra. 



0. EPPELSHEIMI, Keitt. 

 Closely allied to C. linearis, but distinguished by its entirely reddish-testaceous 

 colour ; the antennas are slightly longer and more slender ; the elytra are distinctly 

 more convex, the shoulder-callosities are less developed, and the interstices are more 

 distinctly wrinkled. 



It resembles C. longicotlis and C. crenicollis in colour, but is 

 larger, and has the temples less developed, and the sides of the thorax 

 less serrate. 



C. LONGICOLLIS, Zett. 



A small entirely rust-red, convex species, very finely pubescent ; head narrower 

 than thorax, with short but distinct temples ; antennas with 4th joint somewhat 

 longer than broad, the first two joints of the club strongly transverse ; thorax 

 much narrower than elytra, as long as broad or somewhat transverse, broadest 

 before the middle, and more strongly contracted behind than in front, closely and 

 rugosely punctured, sides rather strongly crenulate, base with a fairly large fovea in 

 the middle ; elytra longish-oval, broadest at the middle and somewhat rounded at 

 the sides, with closely-set rows of punctures, interstices narrow and wrinkled ; the 

 fifth ventral segment of abdomen in the male with a somewhat deep transverse 

 fovea. L. 1/3 — l'G mm. 



C. CRENICOLLIS, Maunh. 



Somewhat convex and parallel-sided, clothed with rather short but conspicuous 

 pubescence, entirely reddish-yellow ; head and antennas as in C. longicollis ; thorax 

 not much narrower than elytra, transverse, half as broad again as long, broadest at 

 the middle, closely and rugosely punctured, sides evenly rounded and distinctly
