pupa state, and the imago appears in the beginning of August. The 

 imago i^Jig' il. 17.) is of a rich brown colour, varied with fulvous pile ; 

 the rostrum being nearly as long as the body, exceeding in this respect 

 every other British weevil. There are several very closely allied 

 British species, one of which feeds upon the acorn. The larva of the 

 nut weevil is figured by De Geer, vol. v. pi. 6. f. 14 — 16.; and its 

 entire history is given by Ilosel, vol. iii. tab. 67. Ratzeburg has pub- 

 lished figures of Balaninus glandium, in its different states, in his 

 Forst'Insecten Col. pi. 5. f. 5., from which Jig. 41. 18., representing 

 the pupa of that insect, is taken. (See also Brit. Cycl.Nat. Hist.; 

 Arboretum Brifanniciim, p. 2028.; and Penny Cyclojj. art. Balaninus). 

 Svvammerdam has described the larva of the common Bal. Nucum 

 (^Book of Nature, ii. p. 871.), but was unable to discover the insect to 

 which it subsequently arrived. Bouche has also given a descrip- 

 tion of the larva in his NaturgeschicJtte, p. 199. Rcisel has also given 

 the transformation of another weevil, the larva of which is more 

 elongated, and is represented (but evidently incorrectly) with legs and 

 prolegs. This insect appears to be the Dorytonius fructuum. Several 

 apparently distinct species are injurious to the apple, a small species 

 depositing its eggs, in the autumn, in the bloom-buds, which are 

 hatched in the following spring ; the larva feeding upon the petals of 

 the flowers, drawing the whole bunch of blossoms into a cluster by 

 means of its webs, and thus destroying it; the larva then undergoes 

 its changes in the earth, like the nut weevil (Salisbury on Orchards, 

 p. 92.) An interesting account of the habits of the Anthonomus 

 Pomorum, which appears to be different from Salisbury's insect, is 

 given by an anonymous writer in the Entomological jSIog. vol. i. 

 p. 34. Ratzeburg has also given figures of the different states of An- 

 thonomus Pomorum in his Forst-Insecten Col. t. v. fig. 8. Bouche 

 has also described its larva and pupa (JVaiurg. d. Insect, p. 200. 

 Mr. Knight, also, in his Treatise upon the Apple, mentions a beetle 

 which commits great destruction upon the apples in Herefordshire. 

 Lyonnct has given the history of a small weevil, which appears to 

 be Anthonomus Pomorum, and which attacks the flowers of the 

 pear in the larva state. It is said by M. Do Ilaan to be the Curculio 

 Pj'ri, but it is evidently not that insect. The larva has the fourth 

 and eight following segments furnished with dorsal pointed tubercles, 

 turned backwards, which it employs as feet, notwithstanding their 

 dorsal position. {JSIem. Posth. pi. 12. f. 13 — 19.) M. Kollar, also, in
