was the case, the larva leaves a hole open at the end of the cocoon, 

 and is in the habit, before its transformation, of going out at this 

 aperture in order to deposit its excrement. He also noticed the ex- 

 treme rapidity with which the moth vibrates its antennae. 



Mr. A. White exhibited some cocoons of an insect from Hon- 

 duras, one end of which was furnished with a flat trap-door, fastened 

 by an admirably contrived hinge, and which he conceived was formed 

 either by a Coleopterous or Cimbicideous insect. He also exhibited 

 a drawing, made by Mr. Angers, of a splendid Papilio in the collection 

 of the British Museum, which, if new, he proposed to name Papilio 

 Iswara. 



The completion of Mr. Westwood's memoir on the Panorpida was 

 read. 



July 5th.— The Rev. F. W. Hope, V.P., in the Chair. 

 Mr. J.F. Stephens exhibited specimens in illustration of the natural 

 history of Nematus Ribesii, St., which had this year committed great 

 devastation upon currant-trees in the neighbourhood of London, 

 stripping trees entirely of their leaves, and being in some places so 

 numerous that not a single currant-tree has escaped. The female 

 deposits its eggs upon the veins of the leaves, upon which the larvae 

 feed as soon as hatched. He had counted as many as fifty- seven 

 upon a single leaf : so rapid was their consumption of the leaves, 

 that he had had a currant-bush completely stripped in a single night. 

 They had first appeared in May, and the larvae now exhibited were 

 the third brood this season. The larva forms its cocoon on the sur- 

 face of the ground. 



Mr. S. Stevens exhibited several nests of Apoderus Coryli which 

 he had found upon oak-trees. 



Mr. Westwood exhibited a new species of (Estrus from India, 

 and a new genus of Mantida with conical eyes from Senegal, the 

 latter from the collection of the Rev. F. W. Hope. 



Mr. Walton exhibited a living specimen of Monochamus Sartor P, 

 taken in a new house at Islington, and two specimens of Hylobius 

 Abietis found crawling in the parlour of his own house, the floor of 

 which had been newly laid down, from which he supposed they had 

 escaped. Likewise a species of Micronyx, Sch. (a Curculionideous 

 genus not hitherto introduced into the native lists), which had been 

 described by Mr. Curtis in the ' Annals of Nat. Hist.' vol. v. p. 280. 

 as a species of Pissodes (P.pygmceus). He also exhibited a new Bri- 

 tish species of Tychius. 



Mr. White exhibited some exotic species of Arachnida and Cimi- 

 cidec, including a new species of the genus Agapophyta from the 

 collection of Mr. James Wilson, and also some new species of Cur- 

 culionidce found in Scotland by Mr. Greville, namely, Magdalis phleg- 

 maticus, Little, Ceutorhynchus viduatus, a new species near C. polli- 

 naris, and Anthonomus pubescens. 



Mr. F. Bond brought for distribution amongst the Members a 

 number of specimens of Callidium violaceum, taken by himself from 

 an old larch post near Kingsbury, Middlesex. 



Mr. Westwood mentioned the destruction committed by the larvae
