20 THE ENTOMOLOGIST. 



SOCIETIES. 

 Entomological Society of London. December 1st, 1886. — 

 Robert McLacblan, Esq., F.R.S., President, in the chair. Mr. 

 W. H. Miskin, of Brisbane, Queensland, Mr. R. E. Salwejs of 

 Folkestone, and Mr. F. W. Biddle, M.A., of Beckenham, were 

 elected Fellows. Mr. Howard Vaughan exhibited a long series 

 of Gnoiilios ohscurata, comprising specimens from various parts of 

 Ireland, North Wales, Yorkshire, Berwick-on-Tweed, the New 

 Forest, Folkestone, Lewes, and the Surrey Hills. The object of 

 the exhibition was to show the variation of the species in connec- 

 tion with the geological formations of the various localities from 

 which the specimens were obtained. Dr. Sharp showed a series 

 of drawings of New Zealand Coleoptera, by Freiherr von 

 Schlereth, which, though executed in pencil, were remarkable for 

 their delicacy and accuracy. Mr. R. Adkin exhibited specimens 

 of Cidaria reticulata, recently bred hy Mr. H. Murray, of Cam- 

 forth, from larvas collected by him near Windermere, on Impatiens 

 noli-me-tangere. Mr. Adkin said that as the food-plant was so 

 extremely local, and consequently difficult for Mr. Murray to 

 obtain, he had endeavoured to get the larvae to feed on some 

 other species of balsam, including the large garden species, 

 usually known as Canadian balsam, but that he had not suc- 

 ceeded in doing so. Mr. E. B. Poulton observed that this 

 statement tended to confirm the remarks he made at a recent 

 meeting of the Society on the subject of the habits of lepidop- 

 terous larvee with reference to their food-plants. Mr. Billups 

 exhibited a number of living specimens of Aleurodes vaporariorum 

 (Westw.), obtained from a greenhouse at Snaresbrook, where 

 they had caused great havoc amongst tomato plants {Ly coper sic am 

 esculentum). He remarked that the species had been first figured 

 and described by Prof. Westwood in the ' Gardener's Chronicle,' 

 1856, and that attention had been recently called to it by Mr. 

 Douglas (Ent. Mo. Mag. for December). Mr. J. Jenner Weir 

 stated tbat plants in his greenhouse had been attacked by the 

 same species. Mr. Poulton exhibited the bright green blood of 

 the pupa of Smerinthus tilice, which is one of man}^ lepidopterous 

 pupse possessing a chlorophyll -like pigment (called meta- 

 chlorophyll by Mr. Poulton) in the blood. The blood of the 

 larva contains the same pigment in a much smaller amount, 

 while in the pupa the additional colouring-matter fixed in the
