stont (Trans. Ent. Soc. Lond., 1906, p. 281). It is hoped that 
the original specimens represented in the fifteen plates of 
Mr. Guy A. K. Marshall’s great paper Ox the Bionomics of 
South African Insects (Trans. Ent. Soc. Lond., 1902, p. 287) 
will be similarly arranged, and carefully labelled for future 
reference and study. Such a collection of the material of 
published illustrations will eventually, it is expected, become 
a prominent feature of the Hope Department. 
8. Assistance in working out the Material of the Department. 
Colonel J. W. Yerbury, who has been so kind a friend to 
the Department for so many years, came to Oxford for some 
weeks in the early spring and completed the arrangement and, 
as far as possible, the determination of the Asilid flies. In 
previous years the Dasypogoninae and the Laphrinae had been 
completed, but by far the largest of the three sub-families, 
the Aszlinae, had been hardly touched. The collection, since 
Colonel Yerbury’s kind help, has been of the greatest value on 
many occasions, and especially in preparing the memoir on 
Predaccous Insects and their Prey, Part I, in which the Aszdz- 
dae are treated more thoroughly than any other group of insects. 
Mr. S. A. Neave, M.A., B.Sc., Magdalen College, on return- 
ing from his expedition to Northern Rhodesia, found his large 
collections of insects pinned and set. He spent much labour 
in arranging them according to their dates and localities, and 
in attaching the labels which were printed in the Department, 
and then again rearranging the collection approximately in 
systematic order, ready for determination. He was unable, 
however, to gather the fruit of all his work, for before the end 
of the year he had started on another expedition to Northern 
Khodesia, hoping to explore the country and study the fauna 
further to the west as far as the coast. During his unavoidable 
absence various parts of the collection will be studied. Thus 
Mr. Shelford has already determined a large part of the 
Orthoptera, while the Hymenoptera are in the hands of 
Colonel C. T. Bingham, who is preparing a memoir upon 
African species of this order.
