Mr. E. Step exhibited a further portion of the "TugweU"" 

 herbarium which he had been renovating for the Society, and in 

 doing so called attention to the verj^ serviceable cabinet which Mr. 

 R. Adkin had presented to the Society to house the collection. 



JANUARY nth, 191-2. 

 Mr. A. SicH, F.E.S., Vice-President, in the Chair. 



Mr. C. G. Gahan, M.A., F.E.S., of the British Museum (Nat. 

 Hist.), and Mr. N. S. Sennett, F.E.S., of South Kensington, were 

 elected members. 



Mr. A. W. Buckstone exhibited a series of Hf/beniia defoliaria, 

 from Wimbledon, West Wickbam, Bexley, and Epping Forest, the 

 majority being from the first-named place. He said that there 

 appears to be more variation in the species now than there was 

 thirty or even ten j^ears ago. There has been a decided decrease in 

 the numbers of the type as compared with the other forms during 

 the last seven years at Wimbledon. Those appearing during the 

 first few weeks show more variation in colour, markings, and size^ 

 than those appearing later in the season, and they, vary from year 

 to year. The non-banded form appears to produce the greatest 

 number of cripples, and is more variable as regards size. The 

 females are not so sensitive lo severe weather, and will enjerge from 

 the pupa under climatic conditions which are almost prohibitive to 

 others of the genus. They frequently emerge after the frost has 

 been on the grass for three or four hours, while the females of H. 

 anrantiaria, H. maniinaria and H. leiiroplKUiria require a South or 

 South- West wind to bring them out. The date of earliest capture 

 was September 30th, and the date of latest capture April 15th. He 

 found them very difficult to breed ; about six hundred larv.e taken 

 in various seasons produced six crippled males and about the same 

 number of females. 



Mr. H. Moore exhibited a huge tree-cricket from the interior of 

 Borneo, and read the following note : — 



"In about the centre of British North Borneo, some six days- 

 journey up the Labuk River, the Exploration Company have cut a 

 path through the dense jungle for some eight or nine miles, to a 

 spot which, for want of a name, they have called Karang, where 

 they are at present proving a copper lode. It was along this 

 jungle path my friend found thn large tree-cricket Emnefia- 

 lodon blanchardi (Brongt), which I now exhibit. Its green colour 

 has faded, but when alive the tegmina have a leaf-like appearance,.
