and (2) the entire change of habit of the larvae 

 which would be necessitated in the spring when it 

 took to its concealed mode of life as compared with 

 the open feeding on mature sallow leaves which was 

 assumed for the autumn. The fact was, of course, that 

 the insect hibernated in the egg. He also was not 

 disposed to agree with Newman that the larvse 

 grew very rapidly. Its normal period could not be 

 much under two months, and some of the lavae 

 probably took a good deal longer. This growth 

 could not be considered rapid, when compared 

 with Melanippe fluctuata, M. sociata, M. galiata, 

 Anticlea nihidata, Corctnia desigiiata, and many 

 others, all of which could go from egg to pupa 

 in about three weeks. His dates for the species 

 ranged from May 30th to September 15th, but 

 the early dates were all for bred examples, and he 

 had not met with it at large before the beginning 

 of July. — Lawrence J. Tremayne, Hon. Secretary. 



Natural History Society of GLASGow.^At 

 the opening meeting of the forty-sixth session on 

 September 29th last, Mr. R. Kidston, F.R.S.E., 

 F.G.S. (and subsequently Mr. Peter Ewing, 

 F.L.S.), occupied the chair. Before proceeding to 

 the business of the evening, the Chairman made 

 feeling reference to the loss the Society had sus- 

 tained since its last meeting in the death of its 

 President, Professor Thomas King. A memorial 

 notice was read by Mr. D. A. Boyd, in which, after 

 giving an account of Professor King's early days, 

 education, and career, he referred to the various 

 offices which he held in scientific societies at the 

 time of his death. Mr. Joseph Somerville intimated 

 the death of Mr. Alexander Mitchell, Belhaven 

 Terrace, a member of the Society. Air. Andrew 

 Gilchrist, Darvel, sent for exhibition the sickle 

 medick, Medicago sylvestris, Fries, from Heads of 

 Ayr, Maybole parish, where he and Rev. D. 

 Landsborough, Kilmarnock, had found the plant 

 abundant in August last. Fresh specimens of the 

 two British species of water parsnip, Shim, were 

 laid on the table; S. erection, Huds., by Mr. 

 Gilchrist, from Galston parish, a new Ayrshire 

 station; and S. Latlfolium, L., by Air. D. Dewar, 

 curator of the Botanic ' Gardens, from a root 

 brought twelve years ago by Mr. C. Sherry from 

 the Royal Canal, Dublin. Mr. A. Somerville, 

 B.Sc, F.L.S., exhibited specimens, six feet in 

 height, of Cladium jamaicense, Crantz (C. Mariscus, 

 Br.), the most handsome of British Cyperaceas. 

 This plant, a new record for the South Inner 

 Hebrides, has been found last month by Dr. T. F. 

 Gilmour and Mr. Somerville growing luxuriantly 

 in a small, sheltered loch on the Kildalton estate. 

 Island of Islay.
