COLEOPTERA. — CURCULIONIDJE. 345 



found in each pot, at a short distance below the surface, and gnaw- 

 ing round the upper part of the root, leaving the lower parts, and the 

 leaves and stems, untouched. They assume the pupa state i^fig. 41. ii.) 

 in the beginning of the summer, and in a few weeks arrive at the 

 perfect state. The larva is considerably more elongated, and less tu- 

 bercular, than that of the nut weevil : it is clothed with numerous 

 short rigid hairs, and is destitute of any rudimental feet. Fuller de- 

 tails of the habits and structure of this larva, and its pupa and imago, 

 are contained in a memoir which I have published in the Gardener's 

 Magazine, No. 85., with supplemental notices in subsequent numbers. 



Bouche has also described and (but very roughly) figured this larva 

 and pupa (Nafnrg. p. 201. tab. 10. fig. IS — 20.); stating that, in the 

 former state, it feeds upon the roots of Saxifraga, Trollius, Sec. 



M. Bouche has also given a description of the larva and pupa of 

 Gymnaetron villosulus, which, in the former state, resides in a gall 

 formed upon the Veronica Beccabunga, a quarter of an inch long. He 

 has also described the larva of Orchestes (Salius) scutellaris Germ., 

 which mines the leaves of Betula Alnus in May ; and is furnished, at 

 the extremity of its pointed terminal segment, with a brown point, as 

 well as with six short legs ; characters not observed in any other Cur- 

 culionideous larvai. The perfect insects are also remarkable for the 

 faculty which they possess of leaping to a considerable distance by 

 means of their incrassated posterior legs. Ratzeburg has given an ac- 

 count of the injuries committed on the elm by Orchestes Fagi, which 

 is represented, in its various states, in his Forst-In&ecten, col. pi. 4. 

 f. 14., from which xnyjig, 41. 19., representing its larva, is copied. Mr. 

 Curtis has also published some additional observations on this genus 

 in his British Entomology. Swammerdam has, however, given us the 

 history of a species of this genus (as proved by his observations upon 

 its saltatorial powers), which resides between the cuticles of willow 

 leaves ; and as proceeding from a vermicle which was destitute of legs, 

 and with the anterior segments of the body flat and broad; at least, if 

 the larva which he figures [Book of Nature, pl.xliv. fig. 9.) be that of 

 the weevil (Ibid. fig. 13.), which is not sufficiently certain from his 

 remarks (page S3.). 



In No. 31. of Loudon's Magazine of Natural History is an account 

 of an American species of this family, which feed upon acorns from 

 Philipsburg in America. The larva {fig. 41. 20 ) of the rare English 

 species Mononychus Pseudacori feeds upon the Iris Pseudacorus. I
