absence of any evidence that it is specifically identical witli any 

 described Equisetiun, I distinguish it as -C. rotiferum. 



Nothing approaching the spore-bearing spikes was seen by 

 me, so that the fructification must remain unknownforthe present.

Obseeyations on an Insect injueiotjs to the Vine. 



By William Macleay, P.L.S., &c. 



At the last monthly meeting of this Society I exhibited some 

 Coleopterous larvae which had been found by Mr. Holroyd to 

 have committed very serious havoc among his grape-vines. I 

 also exhibited cuttings of the injured plants, showing the pith or 

 centre of the branch com2:)letely eaten away along the entire 

 length of the season's wood, with, in some cases, the devastation

 that the grub was the larva of a Curculionidous beetle, but that 

 until I had seen the perfect insect, I could not possibly tell the 

 species or even genus, so much alike were all the larva) of that 

 group. I am now, however, able to speak positively on the 

 subject. 



A few days ago Mr. Holroyd brought me several specimens of 

 both sexes, some — in coitu, of a beetle taken by his gardener out of 

 the injured plants, and which arc most undoubtedly the outcome 

 of the grubs which had caused all the injury. I find them to be 

 specimens of Ortlwrhinus Khigii, of Schonherr. 



The genus Ortliorliinus numbers about 20 species, and is found 

 only in Australia and a few of the Polynesian Islands. The 

 description of it, translated from Lacordaire's " Genera des 

 Coleopteres, vol. G, p. 462," is as follows : "Head subglobulose ; 

 rostrum much narrower than the head, rather robust, straight, 

 cylindrical, longer than the head. Antennae of moderate length,
