SOUTH AFEICA 
hylas , Linn., hovering amidst the numerous Carpenter-bees, the 
commonest of which, Xylocoya caffra, Linn., $, var. mossambica, Grib, 
(with two white rings on the abdomen), it appeared to mimic; of 
the other species X. olivacea, Fabr., and X. divisa, var., single 
examples only were secured, females; the former species is very 
handsome, its thorax being of a beautiful “old gold” colour. A 
Bombyliid fly, Systoechus sp., as well as a male of Catopsilia florella 
(by no means the only one seen), were taken on the same tree. 
The Combretum attracted besides Acraea doubledayi , the Lycaenid 
Axiocerces harpax, a male, and the fine Wasp Belonogaster griseus, $, 
which has a conspicuous yellow spot on the side of the abdomen, 
also a number of the brilliantly-coloured Braconid Iphiaulax whitei. 
On the same plant was found a Lady-bird, Chilomenes sp., which is 
in the National Collection, but without a name. 
On Dombeya flowers, besides Ants, three specimens of the Cetoniid 
Bhabdotis sobrina were taken. 
Certain Aculeates were taken at flowers of one sort or another, 
which it is not now possible to distinguish :— Belonog aster guerini , 
Sauss., $, var. dubius, Kohl, Elis ( Dielis ) fasciatella, $; also the 
long-waisted, black, red and yellow wasp, Eumenes lucasia, Sauss., 
This last was the third specimen known to Colonel C. T. Bingham, 
the type being at Paris and the co-type in the British Museum, from 
Bab-el-Mandeb (2500 miles away). Lastly, a small slender, black, 
white-ringed solitary wasp, a female of a new species of Labus, said 
by the late Colonel Bingham to come very near the Javan species 
that is the type of the genus. It would appear to be the first 
notice of this genus in Africa. Colonel Bingham described this 
as Labus ravus , sp. nov. in MS. ; but before his paper was published 
Mr. Geoffrey Meade-Waldo described a specimen from Natal as 
L. annulatus , sp. nov} 
Other things that were picked up on that memorable day were a 
worn specimen of the pale fawn-coloured Mycalesis simonsi, Butl., one 
of two or three that were seen at one partially shady spot; a large 
“ dry ” Terias brigitta , $ ; a Tryxalis sp.; a fly, Anthrax sp.; and a 
beetle, Zophosis angusticollis, Deyr., found running rapidly over the 
ground at the World’s Yiew, close to the grave of Cecil Ehodes. 
The account of the expedition would not be complete without 
mention of the swarms of the Eed Locust, Schistocerca peregrina, 
which during the drive back to the train rose in glittering clouds on 
every side. It was, however, not without repeated efforts that a few 
specimens were netted out of the many thousands seen.
