Yerbury also presented 17 examples of models and mimics 

 from the same Orders captured (1900) in Inverness, Cromarty, 

 and Sutherland ; also a pair of the mimetic fly GasteropJiihts 

 eqtii from Aldeburgh (1900), and 2 worker bees captured on 

 May 24, 1 90 1, at Belvedere, near Woolwich, together with 

 a pair of the fly Stratioviys longicornis which superficially 

 resembles them. All the specimens were captured by Colonel 

 Yerbury, and bear precise statements of locality and date. 



This gift constitutes a most valuable addition to our Special 

 Collection of the British illustrations of mimicry. 



A fine collection of 378 Diptera from the Lyndhurst district 

 of the New Forest was presented by F. C. Adams, Esq. 

 All the specimens were captured (1900, 1901) by Mr. Adams, 

 and bear exact dates. The condition of the specimens and 

 their beautiful setting are such as to render the gift a most 

 acceptable addition to our poor collection of British Diptera, 

 in which the old specimens are mostly in a bad state, and 

 almost invariably without data. 



One hundred and fourteen British butterflies from exact 

 localities in Hampshire, North Devon, Herts, Berks., Oxon,, 

 Bucks, Suffolk, Kent, and Sussex, and from Finchley, N., and 

 St. Helens, Isle of Wight, were presented by Dr. F. A. 

 Dixey, Wadham College. The data accompanying the speci- 

 mens are most precise and accurate ; the dates of capture 

 range from 1873 to 1901. The great majority of the specimens 

 were captured by Dr. Dixey, but some were taken by members 

 of his family and friends including Dr. G. B. Longstaff, 

 New College. The gift will be of much value to the University 

 Collection of British insects, a most important section of the 

 Department in great need of assistance. 



Twelve equally valuable specimens of British Sat5Tine 

 butterflies from Berks, and North Devon were captured (1877- 

 1901) and presented to the General Collection by Dr. Dixey. 



A set of 8 males and ^"^^ females of the Chalcid parasite 

 Ptcj'oinaiics pupantin were presented by Professor Poulton 

 together with the pupa of Vanessa atalanta, in which the 

 parent had been seen laying its eggs (Sept. 7-8, 1900). The 

 parasitic Hymcnoptera emerged on May 22, 1901.
