Exhibitions. 



Mr. H. St. J. DoNisTHORrE exhibited the second recorded 

 British specimen of Orchestes sparsus, Fahr., taken by him on 

 August 28th last in the New Forest. 



Mr, H. W. Andrews exhibited specimens of Atherix 

 crassij)es, Mg., from the New Forest, the only previously 

 recorded locality in Britain being near Ticehurst, Sussex. 



Mr. G. 0. Sloper exhibited two aberrant forms of Melitsea 

 athalia, S and ? , from Luan, above Corbeyrier, Switzerland, 

 and one S from Martigny, taken on June 26th this year. 

 The tendency of the black markings to supei'sede the fulvous 

 was particularly noticeable in the latter specimen. 



Mr, C. 0. Waterhouse exhibited a gall of some Lepido- 

 pterous insect found on the Califate bushes in Patagonia. The 

 gall resembled that of Cynips kollari, but was hollow, the 

 walls being about ^ inch in thickness. The circular door 

 prepared by the larva was about ^ inch in diameter. The pupa 

 was lying free, without any silk cocoon. It was suggested 

 that the insect was perhaps allied to CEcocecis. 



The President exhibited the Diptera of W, J, Burchell's 

 British collection, and said that he was indebted to the kind- 

 ness of Colonel J. W. Yerbury, Mr. G. H. Verrall, and Mr. 

 J. E. Collin for the determinations. The chief interest of the 

 collection lay in the large pioportion of specimens taken in 

 the garden of Churchfield House, Fulham; the great age of 

 many examples, some dating back over 100 years ; the remark- 

 ably full and precise data characteristic of this exact and 

 keen observer ; and the light thrown upon the movements of 

 the great naturalist, who, after his return from Brazil in 1830, 

 became one of the most isolated and mysterious figures in the 

 roll of British science.
