*' Prothorax in medio, apice excepto, profunde sulcatus," causes me 

 to think that it should be excluded. C. spinipennis Waterh., 

 belongs to Euthyrhinus. 



Of Chcetectetorus Mr. Pascoe* remarks: "There are numerous 

 forms connected with this genus, both Australian and Malayan. 

 I have some doubt of the species from which Lacordaire drew up 

 his characters of the genus, as he describes the rostrum as straight, 

 or nearly so, the eyes finely granulate, and the prothorax without 

 ocular lobes; and he makes no mention of the dilated margins of 

 the prothorax in his otherwise ample description. In treating of 

 the species I think it necessary to exclude all those which (1) 

 have a straight rostrum, (2) and have not the prothorax flattish 

 above and expanded or marginate at the sides, (3) the femora 

 unarmed, (4) the eyes coarsely granulate, (5) the club of the 

 antenna? adnate to the funicle, and (6) all the tarsal joints 

 furnished with erect scales; their presence on the claw-joint is 

 very unusual. These larger scales, which are scattered among 

 the other scales, mostly above and on the legs, seem to be of the 

 ordinary form, only stouter, and more or less erect; they are 

 called setce by Boheman." 



I also exclude all those species which have (7) a distinct 

 circular or pear-shaped fovea or deep longitudinal impression in 

 the middle of prothorax, (8) elytra not parallel-sided, (9) posterior 

 femora passing apex of elytra, and (10) mesosternal receptacle 

 open. 



The species may be obtained under bark, on or under logs, and 

 at night-time whilst crawling over tree-trunks. 



A transverse row of fascicles at summit of posterior 

 declivity. 



Elytra with more or less distinct white fasciae. 

 Without fascicles on posterior declivity. 



Elytra with narrow fasciae , latus Pasc. 



Elytra with wide fasciae - bifasciatus Bohem. 



With fascicles on posterior declivity clitellce Pasc. 



Colour uniform setosus Bohem. 



Without a transverse row of fascicles at summit of 



declivity egenus, n.sp.
