I have seen but two perfect specimens of this species, both of 

 which were taken (in January, 1902) by Mr. J. J. Walker, who 

 kindly presented one of them to me. Both Mr. H. H. D. Griffith 

 and mj^'self, however, have seen numerous fragments of it under 

 stones, but only on the plateau at the summit. The species is 

 certainly the finest of the genus; it is allied to C. 2?usiulata, Baly, 

 but differs in its entirely black colour except for the red tubercles; 

 these also are larger, of different number, shape and position, 

 and all are true rounded tubercles, whilst some of those of C. 

 pustulata appear as thickened portions of interstices; the antennse 

 and legs are stouter, the punctures more numerous, larger and 

 more irregular, and the outline of the prothorax is very different. 

 The reddish tubercles are much the same colour as sealing wax; 

 they vary both on different individuals, and on the right and left 

 side; the largest one on the elytra is always on the shoulder, and 

 is not much smaller than the larger ones on prothorax; they 

 appear in two irregular rows on each elytron, except at the apex, 

 where a single one only is to be seen; the average is six in each 

 row, but the number on each elytron varies from eleven to 

 fifteen; they are always circular, except where two are more or 

 less conjoined.
