56 Dr. G. B. Longstaft on 
The Hon. N. C. Rothschild’s captures on the R. Atbara 
derive especial interest from the fact that, since Klug’s 
time, no collector has worked so near to Klug’s locality— 
Ambukél. 
I have to thank alike draughtsman and printer for the 
admirable plate. 
Col. J. W. Yerbury, R.A., and Mr. Roland Trimea, 
F.R.S., have kindly assisted me with valuable information, 
the latter having placed his MS. notes on Mr. F. C. Selous’ 
captures in the spring of 1911 at my disposal. 
Prof. EK. B. Poulton, F.R.S., and his able assistants have, 
as always, been most kind and helpful. 
Dr. F. A. Dixey, F.R.S., has allowed me to draw upon 
his unique knowledge of the Prerinae and helped to guide 
me through the mazes of the genus Teracolus and steered 
me clear of many pitfalls.
