 1847-8 and 1848-9; by the Society. A box of insects, from G. Dalton, Esq., of 

 George Town, Demerara. 



The following gentlemen were balloted for, and elected subscribers : Joseph S. 

 Baly and James Shepherd, Esqrs. 



Mr. Bond exhibited a portion of the stem of a young ash tree, from near Whit- 

 tlesford, Cambridgeshire, covered with the pupa-cases of a Galeruca?, each being 

 enclosed in the shrivelled spiny skin of the larva, which had a longitudinal slit down 

 the back, after the manner of Tiresias serra. 



Mr. Bond also exhibited some silken production, like felt, supposed to be formed 

 by the larvae of Galleria colonella, which he had found between two planks of wood. 



Mr. Wilkinson exhibited some cocoons of Plutella harpella, found in crevices of 

 the bark of a lime tree. Mr. Bond stated that he had found the larvae of this insect 

 on roses and dogwood : it had been reported to feed on the honeysuckle only. 



Mr. S. Stevens exhibited specimens of Agrotis suffusa and saucia from Venezuela, 

 identical with our British species ; and a living specimen of Ceropacha flavicornis 

 which he had taken the preceding day. 



Mr. H. T. Stainton exhibited some specimens of Micro-Lepidoptera which he had 

 recently bred from leaves gathered the preceding autumn, viz., Lithocolletis Pomifo- 

 liella from hawthorn, and L. Viminiella and Salicicolella from sallow ; also one of 

 Gracilaria auroguttella, from a cone formed by the larva on a leaf of Hypericum 

 pulchrum. 



Mr. Stainton also exhibited a fine series of GUcophora senescens, taken by Mr. 

 Douglas, at Mickleham, in June ; and six new species of British Tineidae, of which 

 he read the following brief descriptions : — 



Micropteryx mansuetella, Z. " Similar to, and size of, M. Calthella, black- 

 headed, with faint pale fasciae on the anterior wings. Near Glogau, in an alder-brake, 

 at the same time as Calthella, on the bloom of Sorbus Aucuparia, in plenty ; more 

 rarely on Spiraea Urinaria and reed-blossoms." (Schlesisch. Tauschbericht, 1844, p. 16). 

 This species has some resemblance to Calthella, but has on the anterior wings some 

 faint indications of purple fasciae, as in rubrifasciella : from both these species it is 

 readily distinguished by its deep black (blue-black) head. Two specimens taken by 

 Mr. Douglas ; locality unknown.
