and Captures in South Africa in 1905. 347 
resting on the under-side of a stalk it would be able to 
see its enemies or prey above it without exposing itself. 
With the Diopsis were Musca? domestica, Linn., Sepedon 
sp. and other small flies; two small Scoliads, Myzine sp., in 
too bad condition to name; and other insects, including 
the Phytophaga, Haltica pyritosa, Erich., Hispa spinulosa, 
Boh. [not H. spinulosa, Schonh.], Chetocnema sp., and 
a small moth, Zinxgeria sp. 
An unnamed Geometer, the cosmopolitan Tineid Plutella 
cruciferarum, Zell., and the Blatta Cirphis [Paraplecta] 
pallipes, Stal., all came to light in the train on the night 
of Sept. 11th between Gwaii and Wankie. 
THE VICTORIA FALLS OF THE ZAMBESI. 
Lat. 18° 0'S. Altitude 3,000 feet. September 12-19. 
This was our furthest point and the locality from which 
we expected most. 
Apart altogether from the magnificence of the Falls 
themselves and the geological puzzles that they afford, 
the locality presents certain peculiarities to the botanist 
and entomologist. 
Picture a rolling sandy plateau a little over 3,000 feet 
above sea level. Low distant hills bound the view, though 
the characteristic South African kopje is for once absent. 
Above the Falls the banks of the Zambesi are low and 
almost flat, the country on either side of the river 
resembling much of that passed through in the railway 
journey from Buluwayo. ‘The forests of South Rhodesia 
are chiefly composed of deciduous trees of moderate size, 
for the most part tending to be flat-topped and so 
harmonising with the horizontal strata and giving the 
landscape a character of its own. The undergrowth of 
scrub is, as a rule, scanty and easily traversed, while the 
coarse grass and other herbage was so sparse as to leave 
much burning sand quite bare; though it must be borne 
in mind that our visit was towards the end of a very dry 
season. Doubtless during the rains much of this sand 
would be covered with vegetation and gay with flowers, 
but as it was we found loose dry sand extending to within 
a very few feet of the Papyrus growing at the water’s edge. 
The banks above the Falls are fringed with a narrow belt 
of shady wood in which (especially on the right bank) the 
small date-palm, Phenix reclinata, is the prevailing tree,
