observed that these insects had all been killed in the cyanide bottle, 

 whilst others in the same setting box, which had been injected with 

 oxalic acid, were left untouched. — The President said that about the 

 beginning of July this year he had noticed, while collecting near El 

 Guerrah, the junction for Constantine, Biskra and Alger, both sexes 

 of the yellow and black Leiicosjns gigas and of another red and black 

 Leucospis, flying in great numbers round a cairn of stones on the top 

 of a hill, and suggested that the common instinct to seek high places 

 might provide a meeting-place for the sexes.— Commander Walker 

 read the following papers : — (1) " Report on a Collection of Bomby- 

 liinte' (Diptera) from Central Africa, with Descriptions of New 

 Species," by Professor Mario Bezzi, Turin, Italy (communicated by 

 G. A. K. Marshall, F.E.S.). (2) " An Enumeration of the Rhynchota 

 collected during the Expedition of the British Ornithologists' Union 

 to Central Dutch New Guinea," by W. L. Distant. (3) " CEstrida

City of London Entomological Society. — October lltli, 

 1911. — Abraxas grossulariata, abs. Eev. C. R. N. Burrows ex- 

 hibited a number of aberrant examples, mostly bred from larvsB 

 collected at Macclesfield and Wallasey ; these included a specimen 

 of ab. lacticolor (Raynor) with basal area of superiors suffused 

 with black, also ab. fidvajncata (Raynor) and others with increase of 

 black marking. — Zygaenids. Mr. E. A. Cockayne a number of five 

 and six spotted specimens of somewhat douljtful identity from a 

 colony found in a field in Berkshire, which produced both forms in 

 June, 1911. — Peronea variegana. Mr. J. E. Gardner a very variable 

 series, mostly collected in a garden at Clapton. — CEdamatoplwrus 

 litJiodactylus. Mr. G. H. Heath a series from S. Wales showing 

 colour variation parallel to that occurring in Pterophorus vionodactylus. 

 — Smermthus p)opuli. Mr. L. W. Newman a long series bred ex 

 selected Bexley parents, ranging from pink flushed forms to pale 

 cream coloured, and including two hermaphrodites, of which ten were 

 bred ex one thousand pupae. — Angerona prunaria : effect of environ- 

 ment. Mr. C. P. Pickett some half dozen series, mostly from same 

 brood, reared ab ovo under different coloured muslins ; the series as 

 shown displayed marked differences in coloration which the exhibitor 

 attributed to the varying environment. — Gcenonympha pampliilus, ab. 

 Mr. J. Riches, a dingy brown specimen with pale patch in marginal 

 area of inferiors, Lewes, August, 1911. — Colias edusa, vars. Mr. A. J. 

 Willsdon specimens from Plymouth and Torquay, 1900, including 

 females without usual yellow patches on black margin of superiors, 

 and the lemon coloured form of var. helice. — Mr. Willsdon recalled 

 having captured a freshly emerged C. hyale early in June of the fol- 

 lowing year.^ — Colias hyale. Mr. L. W. Newman reported that males 

 taken in September and kept for ova showed no inclination to lay, 

 and seemed disposed to hybernate. — Vanessa cardui and Sphinx con- 

 volvuli : short larval period. Mr. Newman recorded that by feeding 

 up larvae in a hothouse he had secured the completion of this stage 

 in three weeks for the former and twenty-six days for the latter. —
