 reticulato-punctato ; antennis ferrugineis, funiculo articulis duobus

 elevato, disco tuberculis quatuor in medio transversim obsito ;

 tuberculis magnis in seriebus tribus digestis, sell, serie interiore 

 quatuor, quorum ultimo maximo postice et propo suturam si to, 

 serie secunda tribus, tertiaque uno majore et duobus minusculis, 

 humeris obsolctis, apicibus tuberculato-productis ; pedibus modice 

 elongatis. Long. 7 lin. 



Hob. Eclipse Island. 



Like P. Waterhousei in habit, but with the two basal joints 

 of the funicle of equal length, and nearly as long as the re- 

 maining joints together. This species is remarkable for the 

 two large posterior tubercles on the elytra, situated close to 

 the suture, and therefore contiguous at the base (in P. Water- 

 housei there is a considerable interval between them) ; besides 

 the eight large tubercles on these organs, there are smaller 

 ones, some of which are scarcely more than the slightly ele- 

 vated interpunctate spaces. Eclipse Island is, according to 

 Keith Johnstone's Atlas, close to King George's Sound, but 

 it seems to have yielded several insects not yet met with on 

 the mainland. The present is the only species of Poropterus 

 I have seen from Western Australia. 



Axides. 

 Rostrum modice elongatum, arcuatum ; scrobes postmedianse, obliquoo. 

 Funiculus 7-artieulatus, articulis duobus basalibus elongatis, primo 

 crassiore, caeteris transversis, gradatim latioribus ; clava magna, 

 4-articulata, quasi ad funiculum adnata. Oculi modice anipliati, 

 tenuiter granulati. Prothorax subconicus, insequatus, lobis ocu- 

 laribus prominulis. Elytra subcordata, modice convexa, dorso 

 parum planata. Rima pectoralis inter coxas intermedias termi- 

 nata, apice aperta. Femora subtus dentata ; tibiw haud com- 

 pressae, intus leviter bisinuatae ; tarsi articulo ultimo elongato, 

 esquamoso. Abdomen articulis duobus basalibus amplis. 



This genus has many of the characters of Chimades, a 

 curious form with ^subquadrangular elytra, and apparently 

 having little connexion with the species described below. 

 Both genera, as well as many others, are allied to Chcetec-
