Champion in Corsica, with a description of one new species." Mr. W. 

 F. Kirby read a paper entitled " Notes on Donjdium westu-oodi, 

 Buchanan White, with observations on the use of the name Dory- 

 dium." Mr. Charles B. Taylor communicated a paper entitled 

 "Description of the larva and pupa of Papilio Iwmerus, Fab." 



March lith. — Colonel Charles Swinhoe, M.A., F.L.S., Vice- 

 President, in the chair. Mr. William Bateson, M.A., Fellow of St. 

 John's College, Cambridge ; Mr. H. Caracciolo, of the Port of Spain, 

 Trinidad ; Mr. G. Dudgeon, of 53, Montague Square, W. ; and the 

 Eev. Frank E. Lowe, M.A., of St. Stephen's Vicarage, Guernsey, were 

 elected Fellows of the Society. Dr. D. Sharp, exhibited a collection of 

 white ants (Termites) formed by Mr. G. D. Haviland in Singapore, which 

 comprised about ten or twelve species, of most of which the various 

 forms were obtained. He said that Professor Grassi had recently 

 made observations on the European species, and had brought to light 

 some important particulars ; and also that, in the discussion that had 

 been recently carried on between Mr. Herbert Spencer and Professor 

 Weismann, the former had stated that in his opinion the different 

 forms of social insects were produced by nutrition. Professor Grassi's 

 observations showed this view to be correct, and the specimens now 

 exhibited confirmed one of the most important points in his observa- 

 tions. Dr. Sharp also stated that Mr. Haviland found in one nest 

 eleven neoteric queens, — that is to say, individuals having the appear- 

 ance of the queen in some respects, while in others they are still 

 immature ; these neoteric queens were accompanied by kings in a 

 corresponding state. Mr. Haviland gave an account of the structure 

 of some of the nests, and of the cells of the females, and stated that 

 two of the species of white ants exhibited certainly grow fungus for 

 their use, as described by Mr. Smeathman, many years ago, in the 

 Phil. Trans, of the Royal Society. Mr. H. Goss remarked that the fact 

 that the different forms of social' insects were produced by nutrition 

 was known to Virgil, who referred to it, and to the subject of Partheno- 

 genesis in bees, in the ' Georgics,' Book iv. Mr. McLachlan, Colonel 

 Swinhoe, Mr. Champion, Mr. Jenner Weir, and Dr. Sharp continued 

 the discussion. Mr. 0. E. Janson exhibited specimens of Dicrano- 

 cephalus adamsi, Pascoe, from Sze-chuen, Western China, and Z). dabryi, 

 Auz., recently received from the neighbourhood of Moupin, in the 

 same district ; he observed that, although the latter had been quoted 

 by Lucas, Bates, and others, as a synonym of adamsi, the two species 

 were perfectly distinct ; the females of both were unknown to the 

 authors when describing them, and presented a remarkable difference, 

 for whilst in dabryi this sex is similar to the male in colour and 

 sculpture, in adamsi it is entirely dull black, with the upper surface 

 minutely and densely punctate. Mr. C. 0. Waterhouse exhibited, for 

 Mr. E. A. Waterhouse, a specimen of Colias edusa, closely resembling 

 C. erate, a continental species, which was taken on Wimbledon 

 Common; a varied series of Chrysophanus phlxas from Barnes Common ; 

 and a series of Lyceena arion, from Cornwall. The Rev. Canon Fowler 

 xead a paper entitled " Some new species of Membracida." Mr. F. 

 Merrifieid read a paper entitled "Temperature experiments in 1893, on 

 several species of Vanessa snad other Lepidoptera." ^ He said that the 

 results tended to confirm Dr. Dixey's conclusions as to the origin of the
