shire. He remarked upon the unusual occurrence of trans- 

 verse lines in this species. 



Mr. F. Noad Clark exhibited photo-micrographs of a 

 number of species of bacteria. They were photographed 

 under a magnification of T V in., a thousand diameters. 



Mr. Hy. J. Turner exhibited some twenty species of butter- 

 flies which he had received from Mr. A. J. Croker, taken in

Mr. Wallace Payne, of Clapham, Mr. Percy Brown, of 

 Balham, and Mr. Donald Peyler, of Clapham, were elected 

 members. 



Mr. W. J. Kaye exhibited living larvae of Orgyia gouo- 

 stigma, from Essex. They were about three weeks out of 

 hibernation, and were feeding on sallow. During the winter 

 they were kept in a cool outhouse, and although an endeavour 

 was made to induce them to feed in January, and again in 

 February, they remained quiescent. Mr. Adkin remarked 

 that he had always found this species difficult to hibernate, 

 the larvae usually drying up about the time when they should 

 commence feeding. 



Mr. H. Moore exhibited a number of Lepidoptera from 

 Durban, Natal, including Daphnis nerii, Agrius convolvuli, 

 Hippotion celcrio, Hippotion eson, Philampclus nicgccra, Egybolia 

 vaillantina, Crishna macropsl, Jana cdulis, etc. 



Mr. Stanley Edwards exhibited a box of Lepidoptera from 

 British North Borneo, and called attention to a number of 

 species resembling those of Great Britain, including the 

 Bornean forms of Phryxus livornica, and Agrius convolvuli. 



Mr. Harrison and Mr. Main exhibited a large number of 

 Aglais (Vanessa) iirtica? from Scotland and various English 

 localities. Several were var. polaris, and a number of speci- 

 mens showed traces of that form, especially in the Scotch 

 examples, while those from Cheshire were generally light. 

 Mr. Kaye pointed out that one of the lines of variation shown 

 by this species was the loss or considerable diminution in 

 size of the upper twin spot on the disc of the fore wing. 

 Mr. Harrison said that there appeared to be no strong local 

 forms of this species. The examples from the north were 

 constantly dark on the under side ; the reverse was the case
