Antennae compressed ; I ho third joint as long as the two preceding 

 together; fourth a little longer, truncate &\ the apes ; til'th to ninth 

 nearl) the same form, but gradually more obliquely truncate at the 

 apex, so that the lower anterior angle becomes more acute but is 

 not produced; the tenth joint is rather smaller, very obliquely trun- 

 cate ; the eleventh narrow, parallel, acuminate at the &]>■ 



This species is very close to C. rugatus, but the lateral oblique 

 ridge of the thorax is placed more posteriorly, and the lateral im- 

 pressions arc not so well defined: the space between the antenna! 

 pit and the base of the mandible is also much greater.

Rather shorter and broader than C. ruber, the thorax more trans- 

 verse, and with the ridge which divides the lateral impressions 

 much more directed forwards; rostrum almost none, i.e., the space 

 between the antennal pit and the base of the mandible is less than 

 half the diameter of the pit, whilst in C. ruber this space is quite 

 equal to the diameter of the antennal pit. The third joint of the 

 antennae is as long as the first, as long as its greatest widt h. obliquely 

 truncate at the apex ; the fourth joint as long as the two preceding 

 together, a little longer than broad, very little narrowed at the 

 base, straight at the apex ; the fifth to tenth about the same Length 

 as the fourth, but gradually diminishing in width, scarcely oblique 

 at the apex, their lower anterior angle a little less than a righl 

 angle ; the eleventh joint much narrower, longer, parallel, acuminate 

 at the apex. The thorax one sixth broader than long, a little nar- 

 rower in front ; disk convex, with a rather fine mesial channel : the 

 sides deeply impressed, the usual oblique ridge very much directed 

 forwards, almost parallel with the lateral margin. Elytra vers 

 dually and very little enlarged posteriorly; each elytron with two 

 narrow slightly raised costal, with an indication of a third.
