Mr. B. G. JTevinson, of 3, Tedworth Square, Chelsea, was elected a Fellow of 

 the Society. 



The President announced that he had appointed as Vice-Presidents, Mr. C. G. 

 Barrett, Mr. E. Saunders, and Mr. G. H. Verrall. 



The President exhibited a specimen of Colias Edusa, var. Helice, with the 

 margins of the wings entirely dark, as in the male ; also a variety of Carterocephalus 

 Palemon, with the hind-wings dark, save for one conspicuous orange spot. Dr. T. A. 

 Chapman, a large series of Endrosce collected during the last few years by himself, 

 Mr. A. H. Jones, and especially by Mr. Tutt ; E. roscida, which is a very distinct 

 dwarf form, and from frequenting marshy flats, must live on lichens gi'owing in such 

 localities, and not on stones as the others do ; E. irrorella, whicli should be the 

 rarest species of the Alps, judging by the comparatively few specimens met with ; 

 E. aurita, in very great variety, including a good many, specimens that are called 

 Kuhlweini, var. alpestris, none, however, reaching the type of Kuhlioeini, but suffi- 

 cient to show with something like certainty that Kuhlweini is simply an extreme 

 form of aurita : E. aurita and E. irrorella are very near together, no point in their 

 anatomy being absolutely distinctive, while the genitalia are practically identical ; 

 E. irrorella always looks much slighter, being lighter scaled, and the hairs short 

 and smootli. It always has a yellow patch on the mesothorax. The venation is also 

 distinctive, yet individuals of each species approach each other completely in each 

 of the distinctive items of the venation, but never in all of them, so far as examina- 

 tion of a number of specimens goes. Except irrorella from England, Finmark, and 

 the Tyrol, and a few aurita from the Tyrol, all were from the Western Alps of 

 Switzerland, Italy, and France. Examples from each locality when sufficiently 

 numerous usually have a special facies. Some, as all those from Arolla, radiate ; 

 those from Bourg St. Maurice are without radiate forms, and so on. Some are more 

 yellow ; others deeper orange ; some more mixed. Elevation tends to produce 

 radiation, but no other general conclusion as to the effect of height, latitude, or 

 longitude, seems fully justified by the specimens. Mr. C. G. Barrett, for Mr. G. O. 

 Day, of Knutsford, a black variety of Aplecta nebulosa, Tr., with white cilia, 

 and an asymmetrical $ var. of Fidonia atoniaria, Linn. Mr. M. Jacoby, an 

 unknown species of HalticidcB. Mrs. Nicholl, a collection of Rhopalocera from the 

 Lebanon district of Syria ; and Mr. H. J. Elwes, on her behalf, read a paper ex- 

 plaining and illustrating the several species included. Among other species, Mr. 

 Elwes drew especial attention to Thecla niyrtale, which, since it was described by 

 Klug in 1832, has remained one of the least known members of the palsearctic fauna. 

 No examples it appears had been taken in the interval until Mrs. Nicholl found it 

 on the high mountains not uncommon in May and June. Y. Asterope was also 

 taken commonly on the coast, the species being tlie sole representative of its family 

 between Syria and Manchuria. The NymphalidcB also showed a great range of 

 variation. Sir John Llewelyn made some remarks on the character of the country 

 through which Mrs. Nicholl had travelled. The following papers were communi- 

 cated : — " A revision of the genus Axtathes, Newm., and allied genera of Longicorn 

 Coleoptera," by C. J. Gahan, M.A. ; and "A Preliminary Catalogue of the Lepido- 

 jitera-Heterocera of Trinidad," by W. J. Kaye. — H. Rowland Beown, M.A., and 

 H. Goss, F.L.S., Hon. Secretaries.
