Entomological Society of London. — September Zrd, 1884 : R. MoLach- 

 LAN, Esq., F.R.S., in the Chair. 



Lieut.-Col. C. Swinhoe, of Winchester, was elected a Member. 



Mr. Coverdale exhibited a fine collection of Micro- and other Lepidoptera 

 mounted in a new fashion on the heads of pins flattened out and turned down at a 

 right angle. 



Mr. Stainton exhibited specimens of Coleophora limoniella and auroguttella, 

 and remarked on their distinctive cliaracters ; and he said that in Mr. Coverdale's box 

 were examples from Shoeburyness that scarcely accorded with the typical limoniella. 



Mr. Billups exhibited smooth spherical excrescences on birch twigs, about the 

 size of small apples. They were hard, and with no trace of insect agency. It 

 seemed to be uncertain whether they were, or were not, the young condition of the 

 " witch knots " on birch which Miss Ormerod states to be duo in the first instance 

 to a Phytoptus. Also Ocypus cyaneus found by Mr. South in Devonshire, and 

 Loxops coccineus captured by himself at Chobham. Also Odynerus reniformis and 

 its parasite Elampus Panzeri, from Chobham. 



Mons. Wailly exhibited, and remarked upon, several silk-producing Eombyces, 

 some of which had been reared in this country for the first time. 



Mr. OllifE exhibited, and remarked upon, a " Cassida " received by Lord Wal- 

 singham from Mr. J. C. arant, of Bahia. It proved to be Porphyraspis tristis, 

 Bohem. With it were the larvae which cover themselves with a coating of filamen- 

 tous excrement, not unlike an inverted bird's nest in miniature, and supported by a 

 furcate anal process ; they fed on cocoa-nut palm. 



Mr. Poulton read a lengthy paper, illustrated by beautifully coloured diagrams, 

 in continuation of his former remarks on larval markings, &c., and their pro- 

 tective associations. He detailed the history of several of the larger Sphir,gid(B 

 from the early larval stages, showing the modifications undergone during growth, 

 and the apparent influence of food, which although seemingly certain, did not appear 

 to be constant. A discussion took place, in which Messrs. White, Stainton, Weir, 

 McLachlan, &c., joined. 



October 1st, 1884 : J. W. Dunning, Esq., M.A., F.L.S., President, in the Chair. 



Haygarth Addison, Esq., of 145, Seven Sisters' Eoad, was elected a Member. 



The Secretary read letters from Drs. Packard and Fritz Midler, thanking the 

 Society for their election as Honoi'ary Members. 



Mr. Jenner Weir exhibited an example of Vanessa cardui from the New Forest, 

 in which the under-wings had blue pupils to the spots. Also a large species of 

 AcrydiidcB from the interior of Africa, of curious robust form, stated to be eaten by 

 the Earthmen of the District (the Kalobari Desert). 



Mr. Horner exhibited a long series of rare British Coleoptera recently captured 

 by him, including Myrmedonia Raworthi, Philonthus astutus, Hoynalota planifrons, 

 eximia, and languida, Stenus morio, Dyschirius extensus, Trichonyx MaerJcelii, 

 Lathridius testaceus, Cryphalus fagi, Phloeotrya Stephensi, and Ocalea latipennis 

 and castanea. 



Mr. J. J. Walker exhibited a large collection of beautiful Lepidoptera obtained 

 during his recent cruise in the Pacific. All were in admirable condition. 



Mr. McLachlan exhibited an example of a species of the Neuropterous 

 Family Nemopteridce, taken by Mr. Walker at Coquimbo, North Chili, and remarked
