nomic part of the collection dealing with mimicry and common 
warning colours. Many of the groups are very beautiful, 
and the whole provides a greatly-needed increase of the 
material for research. A fine set of 15 varieties of Kallima 
paralekta from Java were also purchased from Messrs. Watkins 
and Doncaster. The underside of this butterfly in the position 
of rest presents the most wonderful resemblance to a dead 
leaf. Although this species furnishes the classical example 
of protective resemblance described by Dr. A. R. Wallace, 
D.C.L., in his “ Malay Archipelago,” it has not been hitherto 
represented in the Hope Collection. 
A very interesting series of 323 butterflies, captured ona single 
day in the Potaro District of British Guiana, was purchased 
from Mr. C. B. Roberts. They are as yet uncatalogued. 
ADDITIONS TO THE BRITISH COLLECTIONS IN 1903. 
A specimen of the rare British Anthribid beetle, 7vopideres 
nivetrostris (Kent, 1902), was presented by the captor, A. J. 
Chitty, Esq., M.A., Balliol College. 
A most valuable series of 990 Diptera from a great variety 
of British localities was presented by Lieut.-Col. J. W. Yer- 
bury, R.A. The data are most exact and all the species 
have been carefully worked out by Col. Yerbury. His 
identifications, together with the data of time and place, are 
now printed and affixed to all the specimens. 
The bionomic series has also been greatly enriched by 
Col. Yerbury. Four Asilid flies and their prey, together with 
the Aculeate, Oxybelus uniglumis and its prey (Hertfordshire, 
1902, and Wales, 1902-3), have received printed labels and 
have been catalogued ; while a number of other valuable cap- 
tures of the same kind will be incorporated at an early date. 
Two hundred and eighty-five Diptera, beautifully set 
and in the most perfect condition, were presented by F. C. 
Adams, Esq. With the exception of one from Aberdeen and 
six from Colchester the whole were captured by Mr. Adams 
in the Lyndhurst district of the New Forest (1902). 
A very interesting example of a symmetrically injured
