MR. F. P. PASCOE ON THE CURCULIONIDJE. 



Hextmtis. 



(Cryptorhynchinse.) 



Hostrum modice tenuatum, arcuatum, dimidio apicali nudo, ni- 

 tido ; scrobes laterales ; antennce medio rostri insertse ; scapo 

 longiusculo ; funiculo 7-articulato, art. duobus basalibus elon- 

 gatis, tertio obconico, cseteris ovatis ; clava ovali. Oculi grosse 

 granulati. Prothorace transversus, apice valde angustior, utrin- 

 que rotundatus. Elytra subquadrata, apice declivia. Fe- 

 mora modice incrassata, infra dente angulato armata ; tibice 

 flexuosae, apice tenuiores, unciiiata3 ; tarsi art. tertio angusto, 

 bilobo. Mima pectoralis inter coxas intermedias protensa, apice 

 cavernosa. Episterna metathoracis angusta, distincta. Abdo- 

 men normale ; sutura prima recta. 



* This is one of those genera which, without any strong charac- 

 ters, must be constituted partly on account of their peculiar habit, 

 and partly because their characters collectively are not in accord 

 with those of any other genus. It is apparently allied to Po- 

 ropterus, although the metathoric episterna are very large. 



Hexymus tuberosus. (PI. VII. fig. 3.) H. oblongus, fuscus, in- 

 dumento griseo dense omnino tectus, squamisque subsilaceis ad- 

 spersus ; capite fronte convexo, inter oculos foveato; rostro capite 

 plus duplo longiore, subtenui, apice depresso, fusco, extrorsum sub- 

 tilissime punctulato, basi rugoso-squaraoso ; antennis ferrugineis ; fu- 

 niculo art. duobus basalibus primo plus duplo longiore, cseteris mo- 

 dice elongatis, ultimo obconico, clavae subaduato ; prothorace trans- 

 verso, utrinque rotundato, antice constricto, apice producto, lobis 

 ocularibus subangustis, supra pone medium bicalloso, ad apicem 

 crista cariniformi munito ; scutello distincto ; elytris basi prothorace 

 latioribus, subcompressis, lateribus parallelis, postice declivibus, supra 

 seriatim granulatis, singulo callis oblongis quatuor bene determinatis 

 notato — duobus discoideis ad suturam approximantibus, duobus latera- 

 libus, quorum postico in declivitate sito ; pedibus squamis elongatis 

 magis dispersis. Long. 4 lin. 



Hab. Queensland. 



The following species of Poropterus may be taken as fairly 

 congeneric with the four described by Mr. Waterhouse in the 

 ' Transactions of the Entomological Society ' (ser. 2, ii. pp. 196- 

 200) ; but they do not seem to range very satisfactorily in the 

 genus when we consider it has P. antiqiius for its type. I have 

 yet some twenty approximate species ; and until they are worked
