N. Devon, with v. ronversarin and many intermediates ; Hypsipetes sordidata 

 from Forres, probably bilberry forms, many being very extreme : Larentia 

 didymata from many localities indicative of local races ; and Melanippe fluctuata, 

 including- varied London forms and aberrations, with dark Scotch and Shetland 

 forms. Mr. H. Main, the galls of BiovMza apt era on the rootlets of the oak, 

 some cut open to show the workings, the larvte and the parasitic larvse. 

 Mr. W. J. Kaye, a fine set of the species of butterflies fonning the principal 

 Miillerian Association in Costa Eiea, including 14 species of Wiomiinse, 3 species 

 of Heliconiinie, 1 Pierinse, 1 Eresia, and a new species of Castnia. He also 

 showed a smaller similar mimetic group from Caracas, Venezuela. Mr. Sheldon 

 the series of Eujnthecia innotata and E. fraxinata referred to by him at the 

 previous meeting. Lantern slides were exhibited by Dr Chapman of the dele- 

 gates to the International Congress ; Mr. Tonge, ova of Lepidoptera in situ ; 

 Mr. Main, life-histories of the Snake-fly, Raphidia, the Alder-fly and the jump- 

 ing Saw-fly, Phyllotoma ; and Mr. Dennis, galls caused by Aphids and Mites. — 

 Ht. J. Turner, Hon. Secretary. 



Entomological Society of London : Wednesday, October 16th, 1912. — 

 The Eev. F. D. Morice, M.A., President, in the Chair. 



The President stated that in pursuance of a suggestion approved by the 

 Council, he had written to most of the surviving ex-Presidents of the Society 

 for their portraits, and had already received several. Thanks were voted to the 

 donors. 



The following wei-e elected Fellows of the Society : — Mrs. Ellen M. Waterfield, 

 The Hospital, Port Sudan ; Messrs. Patrick Alfred Buxton, M.B.O.U., Fairhill, 

 Tonbridge, and Trinity College, Cambridge ; Alfred Noakes, The Hill, Witley, 

 Siu'rey ; Norman Denbigh Riley, 94, Drakefield Road, Upper Tooting, S.W., and 

 British Museum (Natural History), S. Kensington, S.W. ; and Heniy S. Wallace, 

 17, Kingsley Place, Heaton-on-Tyne. 



Mr. E. B. Ashby exhibited a case of Rhopalocera from the French, Swiss, 

 and Italian Alps and from Britain. Mr. C. B. Williams, a specimen of an 

 unascertained species of the Protura. This order of primitive insects is chiefly 

 remarkable for the absence of antennae ; they use their front j^air of legs not as 

 locomotive but as tactile organs, holding them out in front of the head when 

 walking, as if to take the place of the missing antennae. Various other 

 instances of similar adaptation were mentioned. Mr. W. J. Lucas, a specimen 

 of Somatochlora alpestris from Porsanger Fjord, east of North Cape, and a 

 specimen of Mschna cserulea (^ horealis), from the same locality. They were 

 captui-ed by Mr. W. G. Sheldon. Professor Poulton brought forward a note on 

 behalf of the Rev. K. St. Aubyn Rogei-s, tending to show that occasional 

 migration, due to excessive droiight, is sometimes a cause of the spread of 

 butterflies into new localities. He also brought forward a suggestion received 

 from Mr. C. F. M. Swynnerton as to one of the causes which may have operated 

 in the special development of mimicry in forest areas. It is that flying insects 

 are often exceedingly difficult to recognise in forest as against veld. It is by 

 no means easy to at once decide on the coloration of an insect seen flying in a 

 blaze of light against a deep shadow or vice versa -. also they so frequently 

 disappear behind foliage after having been in view for a few seconds only.
