on July 1. Also 4 specimens of Sa/atura genutia from Takow, 
The splendid additions to the Hope Collection which the 
University owes, in 1904.as in so many years, to the generosity 
of Guy A. K. Marshall, Esq., are briefly described below. It 
is hoped that many of them will form part of the material of 
a memoir on the bionomics of South African insects, in con- 
tinuation of Mr. Marshall’s important publication in 1902 
(Trans. Ent. Soc. Lond., 1902, pp. 287-584). 
From the neighbourhood of Salisbury, Mashonaland 
(1g03-4), I moth and 28 butterflies, including specimens 
captured 7 coztw of much interest for the study of preferential 
mating between varieties, and 12 examples of the genus Precis. 
Some of these latter are labelled as the “first” or “second ” 
example seen in the season, and are thus of much interest for 
the study of the alternation of wet and dry phases of the 
species. Also 5 examples of butterflies injured probably by the 
attacks of enemies—for the bionomic series. 
Of the highest interest and importance is a series of 5 dry- 
season offspring, 2 ¢ and 3 ?, bred from the eggs laid by 
a wet-season female of Precis antilope, captured at Salisbury on 
March 5, 1904. All 5 bear the dates of hatching, pupation, 
and emergence. The whole series has been set to show the 
under-side of the wings, for the seasonal differences are thus 
best seen; while the parent of the same species, with its two 
offspring, bred by Mr. Marshall in 1902, are arranged to show 
the upper side. 
From the same locality, 36 Hymenoptera to add to the very 
fine series already collected for the Department by Mr. 
Marshall; 8 Hemiptera; 1 Homopteron; 8 Orthoptera; 7 
Coleoptera; 30 Odonata (Dragon-flies) ; 2 Dipterous parasites 
(Zachinidae) bred from the pupa of Precis sesamus. To add 
to the collection for the study and illustration of mimicry— 
14 members of the great Lycoid group; 1 Reduviid bug, 
a member of a striking black and red combination; 9 mem- 
bers (Nov. 1903) of the black white-marked Mutilloid group 
of Carabid and Cicindelid beetles; with an example of the
