the Australian Curculionidse. ^3 



The three following new genera belong, in Lacordaire's 

 system, to the second of his two groups of Cylindrorhininse, 

 which is distinguished by the club of the antennae being di- 

 stinct from the funicle. To the three genera which he referred 

 to it I have already added one, and have now to characterize 

 three more. The table below will render their differentiation 

 easy. All the genera, except Enchymus and two or three spe- 

 cies of PerperuSy have the rostrum as long, or nearly as long, 

 as the prothorax, rather robust, gradually broader towards the 

 apex, scaly, and with one or three carinse above ; the scrobe 

 terminal, and becoming shallower or vanishing behind ; the 

 antennee slender, the club generally distinctly 4-jointe*d ; the 

 eyes ovate, often a little pointed below, and not contiguous to 

 the prothorax ; the fore legs stouter than the others, with their 

 tibife flexuous towards the apex, and the claws free. 



Second abdominal segment as long as the next two together. 

 Body scaly. 



Elytra at the base scarcely broader than the prothorax. 



Scape scarcely impinging on the eye Pantopeus, Schon. 



Scape impinging on the prothorax Perpertis, Schon. 



Elytra at the base broader than the prothorax. 

 Corbels cavernous. 



Scrobe running beneath the eye Ptripagis, Pasc. 



Scrobe not running beneath the eye Catastygnus, n. g. 



Corbels open JEnchymus, n. g. 



Body pubescent Steriplms, Er. 



Three intermediate segments of the abdomen equal . . Centyres, n. g. 



Catastygnus. 



Rostrum modice elongatum, apicem versus gradatim crassius, supra 

 tricaririatum ; scrohes terminales, obliquse, infra medium oculorum 

 currentes. Funiculus articulis obconicis. Prothorax transversus, 

 utrinque rotundatus, basi apiceque truncatus, lobis ocularibus 

 distinctis. Scutellum parvum, distinctum. Elytra basi prothorace 

 multo latiora, oblonga vel subovata, 5 ampliata, magis ovata, 

 postice declivia, humeris prominulis. Pedes validi ; femora in- 

 crassata ; tarsi ai'ticulo tertio fortiter bilobo ; unguiculi divaricati. 



In this genus the scrobe runs obliquely to a point below the 

 middle of the eye, and is nearly straight except at its com- 

 mencement. The first three species here described are tolera- 

 bly homogeneous, the others less so, although preserving all 

 the characters of the genus. 



Catastygnus scutellaris. 



C. fuscus, squamulis griseis sat dense tectus, scutello albo ; clava 

 antennarum ovali haud elongata ; rostro fortiter tricarinato, 

 squamis piliformibus transversim sitis ; prothorace rugoso-punc-
