and Captures in South Africa in 1905. 349 
wooded islets, glides noiselessly through the burning sand, 
coming one knows not whence; and again the same 
mighty river, with scarce a warning rapid or even swirl 
upon its peaceful waters, suddenly draws a veil of spray 
over its face as with a mighty roar it flings itself down 
350 feet into a chasm athwart its channel, and emerging 
thence, one can scarce see how, pursues its long mysterious 
course between grim basaltic crags through the incredible 
zigzags of the Batoka. 
The hotel is situated close to the railway-station, in the 
open forest, about a mile from the Falls, and perhaps 100 
feet above them, though geographically speaking below. 
The first insect to attract notice was a large Acrwa flying 
about the tops of the trees, occasionally as many as a 
dozen together. After the exercise of some patience a fair 
series of specimens and a stiff neck were secured. These 
butterflies proved to be very beautiful, with pinkish fore- 
wings and white hind-wings; they were new to Mr. Marshall, 
but previously known to Mr. Trimen by two specimens 
only and then considered by him to be a variety of A. 
anemosa, Hew., to which Aurivillius gave the name of 
alboradiata. A long series amply proves this form to 
be a new species, which should consequently bear the 
name given to the supposed variety by Aurivillius. If, 
tired of gazing up at these beauties, the eyes were turned 
with relief to the ground, ants might be seen running 
swiftly over the sand with their abdomina borne high in 
the air. They were Camponotus fulvopilosus, De Geer, 
dull grey-black with pale brown hairy abdomen, very 
cryptic in their sandy home. The species was common 
about the hotel and on the way to the Falls. Also running 
swiftly over.the sand a small beetle was taken, a Zophosis 
not in the National Collection. A flowering tree close to 
the hotel produced the widely spread Apis mellifica, Linn., 
race adansonit, Latr., as well as two other bees not yet 
determined. 
The irrigated kitchen-garden of the proprietor attracted 
numerous insects, the most striking being Acrava atolmis, 
Westw., of which about a dozen, all males, were secured ; 
it is a beautiful insect looking blood-red when alive ; with 
them were taken three A. atergatis, Westw.; three male 
A, anemosa, Hew., one of them a dwarf, and two A. 
alboradiata, Auriv., f and 2. With the Acraas were two 
females of Zerias brigitta, Cram., of the dry form, also one
