C. hasalis, n, sp. (PI. II, f. 2). 



Niger, nitldiis ; elytris dimidio l^asali ferrugineo, quadri- 

 costatis, apiceni versus paulo angiistatis. $ . Long. 5 lin. 



Closely allied to C. scutellaris, but relatively broader ; thorax 

 broader, ^vith a deep mesial impi-ession, broader in tlie middle ; 

 there is a deep round fovea at the anterior angle, and a deep 

 impression within the posterior angle, the part between the 

 anterior fovea and the posterior impression raised, so that the 

 impressions are not confluent as in the preceding species. The 

 antenna? are broadei' than in scufella/is, in which the fourth 

 joint is twice as long as broad, whereas in ba-^alis it is not more 

 than ^ longer than broad.
