328 THE ENTOMOLOGIST. 



SOCIETIES. 



Entomological Society op London. — October 4th, 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 

 forms of Polyommatus phlceas (Vizzavona) ; LyccBua astrarche, in which the 

 orange marginal band is very brilliant on upper and under sides of both 

 wings (Vizzavona); Lycmna argiis, the females of which are much 

 suffused with blue, probably var. calliopis ; a series of Vanessa urticm var. 

 ichnusa, bred from larvae found at Vizzavona (4000 feet) ; Argynnis elisa, 

 Satyrus semele var. aristaus, Satyrus neomyris, Coenonympha corinna, both 

 spring and summer brood (Vizzavona); Syrichthus sao var. tlierapne, and 

 many others. Mr. G. C. Champion exhibited, for Mr. G. A. J. Rothney, 

 a number of Methoca ichneumonoides, 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 

 planifrons, Westw. The genus was correctly assigned by Westwood to the 

 ColydiidcB, though described as a Brenthid. Mr. J. J. Walker exhibited the 

 following species of Halobates, viz. : — H. sericeus, Esch., from the Pacific ; 

 H. sobrinus, B. White, from Marquesas Islands ; H. wiXllerstorffi, Esch., 

 from Marquesas Islands; H. princqjs, White, from the China Sea; and a 

 female of H. wullerstorffi, with ova attached. Mr. W. H. B. Fletcher 

 showed a variable series of seventy-five Cymatophora or, bred in 1893 from 

 larvse from Sutherland, a series of about forty 0. ocularis bred-in from 

 stock from Ouudle. Also a series of thirty-three moths, all females, 

 supposed to be hybrids between 0. ocularis male and G. or female, from the 

 above stock in each case, bred as a second brood in August and September, 

 1893. He stated that he placed the reputed parents in a muslin sleeve on 

 a branch of Populus nigra, and did not open the sleeve until the resulting 

 larvse required fresh food. To the best of his belief the female parent had
