Accidentally omitted from last year’s Report. 
In addition to the above, a large amount of work done in 
1907 has been or will be published in the course of the present 
year. Thus Mr. J.C. Moulton, Magdalen College, has devoted 
much time to the preparation of an account of the Burchell 
Brazilian Nymphaline and Hesperid butterflies, and Mr. 
G. Meade Waldo, B.A., of Magdalen College, has studied an 
especially interesting and remarkable case of mimicry in the 
Nymphaline butterflies of Africa. 
11. Szrth volume of Hope Reports. 
The materials stored in the Department are amply sufficient 
for a sixth volume, which will be issued as soon as the present 
Report for 1907 is printed. In addition to the ordinary 
series of octavo volumes, separata of quarto papers have been 
accumulating for some years, and the issue of a volume of 
this size cannot be far distant. Separata for a special volume 
on the Burchell Collection are also steadily accumulating. 
12. Exchange of Hope Reports with the Publications 
of Foreign Entomological Societies. 
The Swiss Entomological Society has exchanged a com- 
plete set of its publications for the five volumes of Hope 
Reports, and will hereafter exchange regularly. The Professor 
desires to acknowledge the generosity of the Swiss Society 
and to express his thanks to Dr. Th. Steck, of Berne, for his 
courteous communications on the subject.
