260 Mr. Frederick Bates on 



wliicli, skirting tlie inferior portion of the eye near 

 its anterior margin, extends itself more or less in a 

 curved line towards the base of the submentum ; throat 

 deeply and transversely channelled (as in Coelomefopus) ; 

 eyes more or less distant from the prothorax, transverse, 

 small, somewhat contracted below by an expansion of the 

 cheeks. Antenme rather short, third joint a little longer 

 than the following, nodose at the end, 4-6 or 4-7 

 obconic, 8-11 gradually broader, compact, depressed. 

 Protliorax variable ; generally it is closely applied to the 

 elyti-a, more or less convex, narrowed in front and be- 

 hind, rounded at the sides, truncate at the apex, 

 bisinuate at the base, with the hind angles acute : base 

 and sides margined, the latter obtusely crenulate or 

 sinuous in the middle. Scutellum small, convex, trans- 

 verse. Elytra oblong, but little wider than the thorax at 

 the base, which is thickly margined, broadest behind the 

 middle, and sinuous towards the apex in consequence of 

 a slight expansion of its epipleura, depressed at the 

 shoulders, but with the humeral angle rather strongly in 

 relief, and embracing the hind angle of the thoi-ax ; cpi- 

 pleuTce entire. Legs moderate ; fore and intermediate 

 tibice more or less arched, obsoletely spurred ; tarsi with 

 the last joint as long as the preceding united, first joint 

 of the posterior pair a little elongate ; intercoxal process 

 broad, and gradually arched at the apex ; mesosternutrh 

 sub-horizontal, broadly concave in front ; prosternal 

 process broad, strongly bisulcate, truncate or obtusely 

 rounded or pointed behind ; metasternum short ; body 

 wingless. 



This genus has all the essential characters of the sub- 

 family under which I have placed it, notwithstanding 

 that it has many points which closely connect it with 

 Iphtlmiitis. Having the epipleurse entire, it must, I sup- 

 pose, range by the side of Folypleurus ; and in that case 

 it will, I think, be necessary to remove both genera to 

 the end of the sub-family, to bring them into closer 

 proximity with Iphtlvhius on the one side, and Cielome- 

 topus on the other. The species are all Australian. 



I know not the Australian genus Baryscclis (Dej, Cat.) . 

 Boisduval's descriptions of the two species that enter 

 therein are so short and unsatisfactory, as to be quite 

 useless.
