128 OfesERVATlONS UPON SPECIËS 



{C. Saccharioî Lansdown Guilding and SphenopTi. liratus Schon., 

 which feed on the sugar cane and of which the larvse hâve the 

 body terminated by a simple single rounded segment). The larva 

 of G. Sommeri is represented by Burmeister as very robust and 

 convex, the dorsum much arched and the body terminated by two 

 porrected horny points. A copy of the figure of the larva of G. Som- 

 meri is added to my plate. 



Fifty years ago I noticed in the Muséum of the Collège of 

 Surgeons of London another larva of this genus having two points 

 at the extremity of the body, more obtuse than those of the larva 

 of G. Sommeri, but Mr. Murray states that he was not able to fînd 

 the spécimen to which I alluded, in that collection. 



The second species of Curculionidse sent to me by M. Puis together 

 with spécimens of its larva and a stem of the plant which it infested 

 in considérable numbers, proved, on careful examination, to hâve 

 no immédiate relationship with the Calandrides but was much more 

 closely allied to the Otiorhynchides especially, in size, colour, form 

 of rostrum and gênerai appearance to the Genus Iphipus of Schon- 

 herr, III, p. 248, which comprises insects from New-Caledonia. 

 New-Holland (and one from Brazil), leading to the supposition 

 that M, Puis' species was not an inhabitant of South Africa, and 

 on submitting a spécimen of it to Mr. Pascoe who has made an espe- 

 cial study of the exotic Curculionidag, he at once informed me that 

 the insect is the species which he had previously described under 

 the name of Tranes (Schon. Vil, p. 129) internatus (which is a 

 native of Queensland, "Western Australia) described by himself 

 (Trans. Ent. Soc. London) 1870, p. 199), as folio ws : 



« T. oblongo-ovatus, pauUo depressus, niger subnitidus ; capite 

 rostroque basi sat fortiter et confertim punctatis, oculis infra con- 

 tiguis; prothorace utrinque antice valde, postice minus, rotundato, 

 in medio linea angusta subobsoleta notato; supra crebre sat fortiter 

 punctato, punctis setuliferis, scutello subrotundato basi constricto : 

 elytris fuscis, prothorace basi paulo latioribus sulcatis, sulcis cate-

 ciliato, corpore infra nitido, rtmote punctato, punctis setuliferis; 

 femoribus crassis, infra excisis, non dentatis Long 5 lin. » 



On communicating this information to M. Puis, he replied to me : 

 « De nouvelles recherches faites me l'ont fait découvrir dans \eZamia 

 coraliipes Hooker qui est originaire d'Australie, ce qui confirme 

 votre opinion, que l'insecte était australien. On m'assure que c'est 

 d'Australie qu'arrive l'insecte, car les horticulteurs n'osent plus 

 acheter certaines variétés australiennes parce qu'il est rare de
