 Henry J. Turner, Hon. Secretary. 



Entomological Society of London: March VMh, 1902. — Dr. F. DuCane 

 Godman, D.C.L., F.R.S., Vice-Presirlent, in the Chair. 



Mr. Benaiah W. Adkin, of Brandon House, Morden Hill, Lewisham ; Mr. 

 E. D. Bostock, of Texall Lodge, Stafford ; Mr. Hubert Edelsten, of the Elms, 

 Forty Hill, Enfield, Middlesex ; Capt, Frederick W. Hutton, F.R.S., of the Canter-

 Westrop House, Highwortli, Wiltshire ; were elected Fellows of the Society. 



Mr. W. J. Kaye exhibited a number of insects from British Guiana, many of 

 them taken by himself, illustrative of Miillerian mimicry. Dr. DuCane Godman 

 remarked that in these regions many different forms of the same butterfly would 

 often occur within a radius of fifty miles, showing a wide range of variation. 

 Professor E. B. Poulton, F.R.S., cocoons of Malacos'oma neustria collected by 

 Mr. Hani in in 1900, spun upon black-currant and apple-trees in his garden at 

 Oxford. All of them had been attacked by birds through the leaf, this being the 

 thinnest part of the cocoon, and the pupa thus more easily abstracted. With 

 regard to the resting habit of Hybernia leucophcearia, he said that he had observed 

 that this moth usually rested in a horizontal position. Dr. Longstaff said that all 

 the specimens he had observed on green stems affected a similar position, and that 

 he had only found one on a birch-tree. Mr. M. Jacoby said that he never found the 

 species on oak at all, but palings, also in the same position, which facts Professor 

 Poulton said tended to show that the protective instinct of the species was retained 

 in such localities. Mr. G. T. Porritt, two bred black Larentia multistrigaria from 

 Huddersfield, and said that the dark form was rapidly increasing in Yorkshire. Of 

 those already emerged and reared from the same brood, three were normal and two 

 dark. Dr. Frederick A.Dixeyread a paper, illustrated by lantern slides, entitled : — 

 "Notes on some cases of Seasonal Dimorphism in Butterflies, with an account of 

 Experiments made by Mr. Guy A. K. Marshall." In the discussion which followed, 

 Colonel Yerbury said that a temporary rainfall in a dry season in dry places 

 had a marvellous effect in producing intermediate and wet-season forms.
