XXIII. South African Aculeate Hymenoptera in the 
Oxford Museum. By the late Co. C. T. Brne- 
HAM, F.Z.S. With Introduction by Pror. E. B. 
PouLTon, D.Sc., M.A., F.R.S. 
{Read May 3rd, 1911.] 
THE Hope Department having in recent years received 
many accessions to its collection of South African Hymeno- 
ptera Aculeata, I asked my friend the late Col. C. T. 
Bingham if he would work out the material, preparing a 
list and describing the new forms. He agreed with me 
that such a memoir would be of value to the students of 
African insects, and he consented to undertake it in the 
intervals of other work. I brought the whole of the 
material to the Natural History Museum and, from time 
to time during the last few years of his life, he devoted 
himself to its study. He often showed me the parts of 
the collection he had worked out and the gradually 
increasing pile of manuscript. What Col. Bingham had 
accomplished at the time of his lamented death is now 
given to the world in the following paper, which also 
iucludes the description of a new South African Aculeate 
from the collections made in 1905 by Dr. F. A. Dixey 
and Dr. G. B. Longstaff, and submitted to the author 
by the naturalist last named. . 
The source of each of the examples studied by Col. 
Bingham is clearly indicated in the paper, but I may 
mention that, in addition to the South African examples in 
the W. W. Saunders Collection, the following recently- 
made collections were submitted to the author: the 
specimens collected by Mr. 8S. A. Neave in Northern 
Rhodesia; by Mr. Guy A. K. Marshall in S. Rhodesia, 
chiefly the Salisbury District ; by Dr. F. N. Brown in the 
Orange River Colony and Natal; by Mr. G. F. Leigh and 
Mr. F. Muir in Natal. 
The types of all the descriptions are in the Hope 
Department of the Oxford University Museum. 
In presenting the labours of the lamented naturalist to 
the Society, I have acted throughout under the skilled 
advice of his friend and fellow-worker Mr. Rowland E. 
Turner.
