aid in the cor/zct determination of these difficult species. 
Several insects of different Orders enter into mimetic associa- 
tions, and have been placed in the bionomic collection. Nearly 
the whole of this interesting set of specimens is catalogued. 
In addition to the above 2 Asilid flies with their prey (Nos. 
113 and 125 in Predaceous Insects and their Prey, Trans. Ent. 
Soc. Lond., 1906, p. 323) were presented by the same kind 
donor. 
Four hundred and forty-five M/antidae from the fine 
collection of Orthoptera presented by Malcolm Burr, Esq., 
M.A., New College, have been incorporated in the general 
collection. Almost exactly half the number are catalogued. 
A male and female of an exceedingly fine new species of 
Buprestid beetle recently described as Sternocera druryt, 
C. O. Waterhouse, were presented by Dr. A. J. Hayes. The 
specimens were captured zz coztu by the donor near Gadarif 
in the Soudan (Feb, 1903). The species was described from 
a single individual in the British Museum, but Dr. Hayes’ 
specimens were also studied by the author and have become 
co-types. Dr. Hayes also presented an example of A/ylabris 
hybrida, a beetle said to be destructive of crops in the Soudan. 
Fifty-three specimens of insects of various Orders, many 
of them illustrating bionomic principles, were presented by 
F. Muir, Esq. They were captured by the donor in 1902-3 
at various localities in the neighbourhood of Durban. The 
collection includes 4 examples of Asilid flies and their prey 
(Nos. 79, 124, 126, 127, in Predaceous Insects and their Prey) ; 
also a number of Hymenoptera with their Dipterous mimics ; 
Lycid beetles and their mimics ; ants and their mimics, both 
Hemipterous and Orthopterous. <A particularly interesting 
specimen is an injured example of the butterfly Protogonio- 
morpha nebulosa, captured May 12, 1902, at Stella Bush, near 
Durban. The butterfly was settled on the under side of . 
a leaf when Mr. Muir saw a bird dart at it and tear away 
about one-third of both hind wings. The bird just missed 
the body of the butterfly. The specimen thus affords the 
strongest support to the interpretation of numbers of speci-
