resembles a leaf of willow, upon which it is frequently found feeding ; the respective 

 larvae of G. quercifolia, P. popuU, and E. fasciaria, when in repose lie at full length, 

 flatly pressed upon a branch or twig, to which, moreover, their colour often so 

 closely approximates, that they are with difficulty discovered, the apparent 

 tumidity of the twig being readily passed over ; the larva of Cidaria silaceata 

 greatly resembles the seed-pod of the Epilohium, on which it feeds ; that of G. 

 papilionaria looks, in repose, much like a birch catkin. Many geometric larvae 

 assimilate in a wonderful degree to the colours and forms of the twigs, stems, or 

 leaf-stalks of their food-plants ; and Mr. Bh'chall has remarked that the coiled up 

 larva of Lithosia caniola is not unlike a little snail-shell, which is abundant in 

 its native haunts. 



And so, the collector's hope of becoming a successful larva-hunter lies, in a 

 great measure, in his aptitude for acquiring a kind of eighth sense — a power of 

 discriminating these living animals from their vegetable environings — a power 

 only to be obtained by experience in the hunting gi-ound.

Entomological Society of London. — F. P. Pascoe, Esq., F.L.S., President" 

 in the Chair. 



Edward Saunders, Esq., of Hillfield, Reigate, was elected an Ordinary Mem- 

 ber of this Society ; Mons. H. H. Hays van de Lier, of Delft, was elected a Foreign 

 Member ; and Mr. J. A. Brewer, of Newgate Street, London, was elected an Annual 

 Subscriber to the Society. 



Mr. Bond exhibited specimens of EpJiestia ficella bred from larvaj, which fed 

 upon cork ; also of the new British Depressaria, olerella, lately detected by Mr. C. 

 G. Barrett near Haslemere. 



Mr. Bond also exhibited specimens of the curious variety of Hepialus humuli 

 from the Shetland Islands, noticed by Dr. Knaggs in the Entomologist's Annual 

 for 1865, p. 98. 



Mr. A. R. Wallace exhibited a fine series of Longicorn beetles collected at 

 Penang by Mr. Lamb ; out of 200 species captured, nearly 70 were new to science. 

 The generic forms were frequently similar to those discovered by Mr. Wallace in 

 Borneo and at Singapore, whilst othei's seemed to represent the Siamese type. 



The Rev. Hamlet Clark (on behalf of the Rev. O. P. Cambridge, who was 

 present as a visitor) exhibited a collection of Lepidoptera, Hymenoptera, and 

 Orthoptera, from the banks of the Nile ; according to the observations of Mr. 

 Pickard-Cambridge insect life was not abundant in Egypt, {or of the Microlepidoptera 

 he had caught every specimen he saw. 



The Secretary read a letter from Mr. Roland Trimen, in which the writer 

 pointed out that Charaxes Argynnides of Westwood was identical with the previously 

 described Nymphalis JaJilusa of Trimen. 



The Secretary also stated that a considerable number of specimens of Basy 

 polia Templi had been captured during the past autumn near Huddersfield by the 

 Rev. J. Collins. 



Mr. Frederick Smith communicated a paper, entitled " Wasps and their 

 Parasites in 1864," by S. Stone, Esq., F.S.A. ; after which, Mr. Smith made some 

 remarks on the various diseases prevalent amongst Wasps.
