Clevedon. — After the first week or two, insects at ivy Lave been 

 much scarcer. I took my first Dasycampa rubiginea last Saturday 

 night. Petrificata is very scarce this autumn. I took two sjiecimens 

 of Xylina semihnmnea the second week in September, much earlier than 

 usual, but have not seen any more. — J. Mason. October 2?>rd, 1893.

Entomological Society of London. — October ith, 1893. — Mr. F. 

 Merrifiold exhibited siiecimens showing the effects of temperature in 

 the pupal stage on several species of Lepidoptera. Vanessa pohjchloros 

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

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

 in the feniale ; they Avere striking on tlie under side. Several examples 

 of the striking effect produced by temperature on the summer emergence 

 (prorsn) of Arasclmia lerana Avere exhibited. Some Vanessa io showed 

 the gTadual disintegration by exposure to a low temperature, of the 

 ocellus on the fore wing, Avhich 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 liis experience of V. c-albnm 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 Jul}^ 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 

 Polyonimatus phlceas (Vizzavona) ; Lyccena astrarche, in which the 

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

 lioth wings (Vizzavona) ; Lyctena argns, the females of which are much 

 suffused with blue, probably var. caUiopis ; a series of Vanessa nrtico', 

 var. ichnusa, bred from larvfB found at Vizzavona (4,000 feet) ; Argynnis 

 elisa, Satyrus semele var. aristmus, Satyrtis neomiris, CoinonympJia corinna, 

 l)oth spring and summer bi"ood (Vizzavona) ; SyricMus sao A-ar. therapne, 

 and man}^ others. Mr. G. C. Champion exhibited, for Mr. G. A. J. 

 Kothney, a number of Methoca ichnetimonokles, Latr. (female), taken at 

 I iexhill, Sussex, shoAving great A^ariation from the usual large l)lack and 

 red form to a small and nearly l)lack one. Dr. D. Sharp exhiliited a 

 pupa of Gallerta melonella, on Avliich the eggs of a parasitic Hymenop- 

 teron, as he believed, had been deposited Avliilc the insect Avas in the 

 cocoon. He also exhibited from the collection of Mr. Alexander Fry^ 

 tlie hitherto unicpie Aprosfovw planifrons, Westw. The genus Avas 

 correctly assigned liy WostAvood to the Colydiklce, though descril)ed as a 

 IJrenthid. Mr. J. J. Walker exhibited the folloAving species of 

 Halobates, A'iz. : — H. sericeus, Esch., from the Pacific : H. sobrinus, 

 B. White, from Marquesas Islands; H. ivullerstorffi, Esch.. from 

 Marquesas Islands ; H. princeps, White, from the C'hina Sea ; and 

 a female of H. iciiUerstorfi, Avith ova attached. Mr. W. H. B. Fletcher 

 showed a \'ariable series of scA^enty-fiA^e CymatopJiora or, bred in 

 1893 from larvfe from Sutherland, a series of about forty C. ocvlaris 

 l)red-in from stock from Oundle. Also a series of thirtA'-tlu'Cc moths.
