marked, the summer and winter types must necessarily alternate, but supposing the 

 Northern States to become uniformly cold, the Southern uniformly warm, what 

 would happen ? Was it not obvious that the winter form of C. Eurytheme would 

 be perpetuated in the north, while the summer form would be prevalent in the 

 south ? A further note from Mr. Cockerell was also read with regard to Agrotis 

 suffusa, Hiib., which he said was abundant in America. — H. W. Barker, Ron. 

 Secretary. 



Entomoiogical Society of London : March Ith, 1888. — Dr. David Sharp, 

 F.Z.S., President, in the Chair. 



Mr. Frederic Pennington, Jun., of Broome Hall, Holmwood, Surrey ; Mr. W. 

 Crush, of Westcombe Park, Blackheath, S.E. ; and Mr. J. P. Cregoe, of Charleston, 

 U.S.A., were elected Fellows. 



Mr. J. H. Leech exhibited, and made remarks on, a number of butterflies 

 forming part of the collection made for him during last summer by Mr. Pratt, at 

 Kiukiang, Central China. The specimens exhibited included Papilio macilentus 

 (hitherto only recorded from Japan), varieties of P. Sarpedon, and a supposed new 

 species of Papilio ; a series of Sericinus Telamon ; Acrcea Vesta (varieties) ; 

 Charaxes Narcceus, and var. mandarinus (the latter being the common form at 

 Kiukiang) ; PalcBonympha opalina, Butl. ; new or unknown species of Lethe, Apa- 

 tura, and Neptis ; and a series of Argynnis Paphia, with the var. Valezina of the 

 female. Mr. Leech stated that all the females of A. Paphia taken at Kiukiang 

 belonged to the var. Valezina, the typical form of the species being unknown there. 



Mr. Poulton expressed his interest in Mr. Leech's statement that Valezina was 

 the only form of the female of Argynnis Paphia known at Kiukiang, and said he 

 considered this fact would probably throw a new light on the question of the 

 dimorphism of the species. 



Mr. Jenner Weir said he had in the course of years obtained a series of forms 

 intermediate between the typical female and the variety Valezina. Mr. McLachlan, 

 Dr. Sharp, and Mr. Leech continued the discussion. 



Mr. Champion exhibited, for Mr. J. J. Walker, E.N., about 950 species of 

 Coleoptera, recently collected by the latter near Gibraltar. Mr. McLachlan called 

 attention to the large number of water-beetles included in Mr. Walker's collection. 

 Mr. Kirby suggested that the attention of the Imperial Institute should be called 

 to the interest attaching to the exhibition of local collections of insects from British 

 Colonies and possessions. 



Mr. Verrall exhibited living specimens of Aspidomorpha sanctce-crucis, and 

 another species unnamed, from the caves of Elephanta. 



Mr. Slater exhibited specimens of a species of weevil which had been doing 

 much damage to maize sent to the Colonial Exhibition. 



Mr. W. White read a paper on " Experiments upon the Colour-relation between 

 the pupae of Pieris rapce, and their immediate surroundings," which comprised a 

 detailed account and discussion of a series of observations carried on at the author's 

 instigation by Mr. G-. C. Griffiths, of Bristol. The various experiments were 

 intended to act as a further test of the conclusions arrived at by Mr. E. B. Poulton 

 in his paper on the subject in the Transactions of the Eoyal Society; and to effect 

 this object, different and additional influences had been brought to bear on these 

 pupae, so that an analogy might be drawn between the two sets of results. 



Mr. Poulton, Lord Walsingham, Mr. Jacoby, Dr. Sharp, Mr. White, and others 

 took part in the discussion which ensued. — H. Goss, Hon. Secretary.
