Thi.s species has about the size and shape of G. hrunnipes 

 and C. hidens, but is more strongly punctured. Its non- 

 metallic deep red colour distinguishes it from all the other 

 species known to me. 



It occurred under bark and on brushwood.

 tumido. rugose, medio sulca transversa curvata hevi impresso, clypeo 

 transverse strigoso, margine arcuato ; protborace irregulariter punc-

Two specimens of this, apparently representing the two 

 sexes, were found in rotten wood. It is a very well- 

 marked form, wdiich may be compared with C. jjosticus, 

 Germ., although not closely related to that or any other 

 known species. It is of similar colour and form to 

 G. jyosticns, althougli rather larger, and the elytral costse 

 are similar, but much more prominent, and extending over 

 half the total area of the elytra. The lines of punctures 

 are fewer, and each puncture contains an elongate white 

 scale. The most distinctive feature, however, is the 



* As these insects have been measured sometimes in the rolled-up 

 and sometimes in the extended condition, it is necessary to say that 

 I have given measurements of them in the condition of normal 

 extension.
