in the Hope Department, where it can be studied by all 
naturalists interested in bionomic questions. The paper itself 
is by far the most important publication dealing with Oriental 
insect bionomics which has appeared since Alfred Russel 
Wallace’s classical monograph on the Malayan Papilionidae 
(Trans. Linn. Soc., Vol. XXV, p. 1, 1868). 
A paper describing his first research in the Department, 
undertaken in 1893, was published by the Professor (Trans. 
Ent. Soc., Lond., 1903, p. 311). The delay was occasioned 
by the drawings and manuscript having been mislaid during 
the alterations to the Department in 1894. The experiments, 
in which Mr. Holland rendered the most valuable assistance, 
proved that an environment of lichen-covered bark produces 
the most remarkable effect upon the colours of certain cater- 
pillars. 
The third volume of Hope Reports dealing exclusively 
with African Zoology, issued early in the year 1903, was 
described in the Report for 1902. Later in the year (Nov. g) 
the fourth volume appeared, containing a variety of memoirs 
which were published between the years 1900-1903. It in- 
cludes eleven papers dealing with insect bionomics and other 
questions relating to evolution and natural selection in this 
group of animals, by the following writers:—Mr. Nelson 
Annandale, BVA: Balliol College; Dr. .F.) A: Dixey, D.M.; 
Wadham College; Mr. R. Shelford, M.A., Curator of the 
Sarawak Museum; Mr. Guy A.K. Marshall, F.Z.S. ; and the 
Professor. The volume also contains eight papers dealing 
with systematic and faunistic questions by the following 
authors:— Mr. W. L. Distant; the Rev. O. Pickard-Cam- 
bridge, F.R.S.; Mr. S. A. Neave, B.A., Magdalen College; 
Mr. Edward Saunders, F.R.S.; Col. J. W: Yerbury, F.Z.S. ; 
and the Professor. 
The foregoing statement is very far from completing the 
record of the help received from kind friends of the Hope 
Collections. The staff of the Insect Department of the 
British Museum of Natural History have, as in previous years, 
rendered the most valuable assistance, and the Professor has
