presented by Col. Yerbury, together with 2 Hymenoptera 
Aculeata from Kent and Woolmer Forest. 
A fine set of 106 British Coleoptera from the most varied 
localities, with excellent and precise data, was presented by 
Horace A. Donisthorpe, Esq. 
Five fine specimens of Gvapta C.-album, illustrating the 
seasonal variation of the species in England, bred, about 1889, 
by Mrs. E.S. Hutchinson, at Leominster. Presented by Com- 
mander J. J. Walker, R.N. 
Twenty-eight specimens from Barton Mill, Suffolk ; Wicken 
Fen; and Teignmouth (1go0-1g01), were presented by the 
captor, Mr. A. H. Hamm. They consist of groups of synapo- 
sematic Hymenoptera and mimetic Diptera, each assemblage 
captured at one time upona single patch of flowers. They are 
an interesting addition to the bionomic part of the collection. 
Two moths taken at Ivy-bloom (1904) at Mortehoe, N. 
Devon, were presented by the captor, G. B. Longstaff, Esq., 
D.M., New College. 
Three insects from St. Helens, Isle of Wight, were pre- 
sented by the Professor. 
Very interesting evidence of the attacks of birds was 
supplied by Mr. Fred Birch in a specimen of Zhecla quercus 
from Arnside Knott, near Grange, Lancashire (Aug. 1898). 
A bird was seen to dart at the spot where the butterfly was 
settled, and the insect, when captured, exhibited symmetrical 
injuries, such as would be caused by a snip taken out of both 
wings when in contact in the position of rest. 
Similar indirect evidence is very finely exhibited by a 
specimen of Papilio machaon, in which a snip has been taken 
out of all four wings at the precise spot in the margin where 
alone this is possible as the result of a single injury, viz. 
where the fore and hind wings overlap and come into contact 
with the corresponding parts of the opposite side. The 
specimen was taken in the Norfolk Broads, in June, 1403, by 
the donor, A. Lofthouse, Esq., who observed the injury on 
the specimen before capture. 
An Asilid fly and its prey, captured at Walton, Surrey, on
