8 
papers, dealing almost exclusively with African natural history, 
were amply sufficient to make up a volume, it appeared con- 
venient to withhold a number of earlier publications con- 
cerned with material from other parts of the world. It is 
consequently anticipated that Vol. IV will be issued at no 
distant date, perhaps towards the end of the present year. 
It was much hoped that another important memoir on the 
bionomics of Bornean Insects by Mr. R. Shelford, MEAS 
Curator of the Sarawak Museum at Kuching, Borneo, would 
have appeared in 1902, but there was some difficulty in the 
production of the five coloured plates. The paper will be 
published in the Proceedings of the Zoological Society in 
April next. 
In the preparation of all these publications written in the 
Department, or by naturalists in various parts of the world in 
constant communication with the Department, the kindest 
assistance has always been received from Sir George Hampson 
and the whole staff of the Insect Department of the British 
Museum of Natural History. I particularly wish to thank 
Mr. C. O. Waterhouse, Mr. C. J. Gahan, Mr. G. J. Arrow, Mr. 
F, A. Heron, Mr. E. E. Austen, and Mr. R. I. Pocock (of the 
Arachnid Department), from all of whom I have received con- 
stant help. The following naturalists working in the British 
Museum have also rendered the kindest assistance, Colonel 
C. T. Bingham in the Hymenoptera, Colonel J. W. Yerbury 
in the Diptera, and Mr. W. L. Distant in the Hemiptera. 
All three naturalists contributed important sections to 
Mr. Marshall’s memoir. I also desire to acknowledge the kind 
assistance of Mr. M. Jacoby, the Rev. H. S. Gorham and 
Dr. Karl Jordan. 
The measure of success in research achieved during the 
past year by the Department is above all due to the efficient 
help of my assistants, Mr. W. Holland and Mr. A. H. Hamm, 
who have taken the keenest interest in the progress of the 
work, to Dr. F. A. Dixey in Oxford, and to Mr. Guy Marshall 
both in South Africa and in England.
