Mr. R. South exhibited a remarkable variety of Polyommatus PJilceas, caught 

 by him in North Devon in 1881. 



Mr. R. W. Lloyd exhibited a living specimen of the species of Ocnera taken 

 in London amongst merchandise imported from Ispahan. 



Mens. A. Wailly exhibited, and read notes on, a number of cocoons of Antheraa 

 assamensi's, A. Eoylei, Actias Selene, Atfacus ricini, &.C., lately received from 

 Assam ; also a number of nests of cocoons of Bombyx rhadama — the silk of which 

 is used by the Hovas in the manufacture of their stuffs called " Lanibas " — from the 

 island of St. Mary, Madagascar. 



Mr. H. J. Elwes read a paper on "The Butterflies of Sikkim," the result of 

 many years of collecting in that wonderfully rich district of the Himalayas. He said 

 he had been enabled to complete his observations during the enforced delay at 

 Darjeeling of Mr. Macaulay's Mission to Tibet, of which he was a member. He 

 stated the number of species occurring in this small district to be about 530, which 

 is greater than the number hitherto found in any other district in the Old World. 

 Of these the greater part only occur in the hot valleys at an elevation of 1000 to 

 3000 feet, and these are for the most part of a purely Malayan character, whilst those 

 found in the middle zone are in many eases peculiar to the Himalayas; and the few 

 species from the alpine parts of the country at 12,000 to 16,000 feet are of a European 

 or North Asiatic type. An important feature in this paper was the numerous obser- 

 vations taken on the habits, variation, seasons of appearance, and range of altitude 

 at which the various species occur, for which Mr. Elwes said he was largely indebted 

 to Herr Otto Moller, of Darjeeling. The paper concluded with an analysis of the 

 species and genera as compared with those found in the North-West Himalayas and 

 in the Malay Peninsula. Mr. J. H. Leech, Dr. Sharp, Mr. Elwes, and others took 

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