 SCIENTIFIC SOCIETIES, 



Entomological Society of London. 



October 4, 1893. — Henry John Elwes, Esq., F.L.S., F.Z.S., President, 

 in the chair. 



Mr. Arthur Ernest Gibbs, F.L.S., of The Hollies, St. Albans, was 

 elected a Fellow of the Society. 



Mr. F. Merrifield exhibited specimens showing the effects of temperature 

 in the pupal stage on several species of Lepidoptera. Vanessa polychloros 

 was much darkened, especially towards the hinder margin, by a low 

 temperature. Vanessa c-album showed effects on both sides, especially in 

 the female ; they were striking on the under side. Several examples of the 

 striking effect produced by temperature on the summer emergence (prorsa) 

 of Araschnia levana were exhibited. Some Vanessa io showed the gradual 

 disintegration, by exposure to a low temperature, of the ocellus on the fore 

 wing, which in the extreme specimens ceased to be an ocellus, and was a 

 remarkable confirmation of Dr. Dixey's views of the origin of that ocellus, 

 as exemplified in the plate attached to his paper in the Entomological 

 Society's Transactions for 1890. Mr. Goss stated that in his experience 

 of V. c-album in Northamptonshire, Gloucestershire, Herefordshire, and 

 Monmouthshire, the form with the pale under side was the first brood, 

 occurring in June and July ; and that the second brood, occurring from 

 the end of July to October, was invariably dark on the under side. 

 Mr. Jacoby, Mr. Merrifield, and the President continued the discussion. 



Mr. A. H. Jones exhibited Lepidoptera collected in Corsica in June 

 last, including dark forms of Polyommatus phlceas (Vizzavona) ; Lycana 

 astrarche, in which the orange marginal band is very brilliant on upper 

 and under sides of both wings (Vizzavona); Lyccena argus, the females 

 of which are much suffused with blue, probably var. calliopis ; a series 

 of Vanessa urticce var. ichnusa, bred from larvae found at Vizzavona (4000 

 feet); Argynnis elisa, Satyrus semele var. aristceus, Satyrus neomiris, 

 Ccenonympha corinna, both spring and summer brood (Vizzavona); 

 Syrichthus sao var, therapne, and many others. 



Mr. G. C. Champion exhibited, for Mr. G. A. J. Rothney, a number of 

 Methoca iclineumonoides, Latr. (female), taken at Bexhill, Sussex, showing 

 great variation from the usual large black and red form to a small and 

 nearly black one. 



Dr. D. Sharp exhibited a pupa of Galleria melonella, on which the 

 eggs of a parasitic Hymenopteron, as he believed, had been deposited while 

 the insect was in the cocoon. He also exhibited, from the collection of 

 Alexander Fry, Esq., the hitherto unique Aprostoma planijrons, Westw. 

 The genus was correctly assigned by Westvvood to the Colydiidcc, though 

 described as a Brenthid.
