bisulphide of carbon.* Running along the branches of the 
tree-/pomexa, near the Leaping Waters, were a number of 
another ant, Polyrachis schistacea, Gerst., which we had 
seen at the Matopos on Sclerocarya caffra. 
The Coleoptera met with were not very numerous, but 
comprised Pogonobasis sp. (in the National Collection, but 
without a name), which was taken on the ground by Miss 
L. 8. Gibbs; two specimens of Scymaus sp.; three weevils, 
Bagous cenosus, Gyll., which Mr. G. A. K. Marshall had 
previously seen from Uitenhage, Cape Colony, only; 
Rhabdinocerus brachystegix, Mrshl.. (in litt.) and Xenorrhinus 
inculius, Fst., the first specimen of the latter that Mr. 
Marshall had seen; also a EKumolpid, Pseudocolaspis 
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 “Red Locust,” Schistocerca peregrina, Oliv., 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 (described 
as n. sp. in April 1905), was to be found, together with a 
spotted species with sinuated lip, Melania victoriv, Dohrn. 
The Lerr Bank of the river differs somewhat from the 
right. The ground does not lie quite so low in reference 
to the water, there is more wood and scrub but less grass 
and fewer palms. <A female Limnas chrysippus, Linn., was 
seen at water; of the Acrvx the commonest was A. encedon, 
Linn., males predominating, while single female specimens 
of A. atoliis, Westw., and 4A. ancmosa, Hew., turned up. 
Precis clelia, Cram., was fairly common, and P. sesamus, 
Trim., 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 Selenois gidica, Godt. 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 7. omphale, Godt., a male, “and 
T. eris, Klug, a female, the latter at Combretum flowers,
