356 STUDIES IN AUSTRALIAN ENTOMOLOGY, XV., 



Prosternum with intercoxal part longitudinally channelled and 

 with one setigerous puncture on each side. Posterior coxae with 

 one setigerous puncture; posterior trochanters with a setigerous 

 puncture on inner side near base. Length 19*5, breadth 7*2 mm. 



Hab. — Victoria : Grampian Mountains (unique; Coll. French). 



Belongs to the C. Icevipenne group,* which includes C. Icevi- 

 penne Macl., C. ineditum Mac]., (I have doubts as to the 

 distinctness of these two species), C. co7'dipenne SI. (remarkable 

 for having the paragense setigero-punctate beneath suborbital 

 scrobe), and C. politulumj Westw. C. morosum is allied to 

 C. Icevipenne^ but differs by colour wholly black; prothorax more 

 parallel on sides, much more lightly narrowed to anterior angles, 

 posterior angles more prominent and marked, border much more 

 widel}' reflexed; base of elytra without ocellate punctures near 

 humeral angles; intermediate tibiae stouter and with a more 

 decided spine at outer apical angle. It is remarkable to find in 

 C. morosum the basal declivity absolutely without punctures; 

 another black Victorian species, viz., C. ainplipenne SI., has only 

 one puncture on each side, and C. lepidum SI., has sometimes the 

 base with one puncture, sometimes with none; C. lepidiim has no 

 affinity to C. morosum and C amplijyenyie, and these two latter 

 species differ decidedly from one another. 



Genus Carenidium. 



Carenidium longipenne, n.sp. 



Elongate, depressed, Isevigate. Labrum deeply emarginate; 

 prothorax very little broader than long, two marginal setigerous 

 punctures on each side; elytra long, narrow, impunctate, strongly 

 bimucronate at apex, border not dentate at humeral angles; 



*Cf. these Proceedings, 1900, p.366. 



1 1 believe from Westwood's figure of C. politulum that it exactly 

 resembles G. Icevigatiim Macl., in form of legs, shape of prothorax and 

 colour; in fact, I have always inclined to think Westwood's description was 

 founded on a form conspecific with C. Icevigatum, in which the two discal 

 elytral punctures were absent.
