seen; also a Eumolpid, Pseudo-colaspis chrysitis, Gerst.; and two 
Heteromera of the genus Opatrum, under dead wood. Two specimens 
of Adesmia intricata, Klug, a Heteromeron only represented in the 
National Collection by specimens from Mozambique, were found 
crawling on the ground near the Leaping Waters. 
The Eed Locust, Schistocerca peregrina, was by far the most 
common and most conspicuous of the Orthoptera; as usual it was 
chiefly found among coarse grass, but could not be said to be 
gregarious. 
In shallows in the river just above the Falls, a small banded 
Water-snail, Cleopatra morrelli, Preston, was to be found, together 
with abundance of a spotted species with sinuated lip, Melania 
victoriae, Dohrn. The former had been first found in the same 
locality not long before by Mr. Morrell and described as recently 
as April, 1905, by Mr. H. B. Preston. 1 
The Left Bank of the river differs in character from the right. 
The ground lies somewhat higher, there is more wood and scrub but 
less grass and fewer palms. A female Danaida chrysippus was seen 
at water; of the Acraeae the commonest was A. encedon, males pre¬ 
dominating, while single female specimens of A. atolmis and A. 
anemosa turned up. Precis clelia was fairly common, and P. sesamus 
was seen, as is its wont, fluttering about and settling under the shade 
of a dark bank. 
The Whites were represented among our captures by two male 
Belenois gidica. Teracoli were far less common than on the right 
bank, probably because there was less of the open grassy country in 
which they delight; single specimens only of T. omphale, a male, 
and T. eris, a female, the latter at Combretum flowers, were secured. 
Terias was represented by a female senegalensis, Boisd., of the usual 
dry-season form, but also by a male brigitta , of distinctly “wet” 
character—a notable exception among so many very markedly “ dry ” 
butterflies. 2 A male and two females of Catopsilia florella were 
secured while feeding on the large-flowered species of Combretum that 
grows in the Zambesi scrub; this butterfly was almost certainly seen 
more than once on the right bank, but eluded capture, for Catopsilia 
is very swift of flight and hard to net save when busy honey¬ 
gathering. Papilio demodocus was taken on the Knife Edge near 
the eastern extremity of the Falls.
