and Captures in South Africa in 1905. 337 
Fahr.; also a Lady-bird, Hxochomus nigromaculatus, Goez., 
which is occasionally found in Britain. 
Under stones were two Pentatomid bugs, Dalsira modesta, 
Fabr., and the lance-head-shaped Gonopsis angularis, Dall., 
also Lygevus rivularis,Germ.; there were also several other 
bugs that are not yet named. Along with the bugs were 
several Blatte and a black and red scorpion. A number of 
as yet undetermined Acridians were also taken. 
By far the most interesting insect met with at Johannes- 
burg was a Homopteron, Gyaria walkeri, Stal., allied to 
Flata, a genus well known from its alleged resemblance 
when at rest to a spike of flowers. It is of a creamy-white 
colour with eyes of a beautiful pinkish hue, which is 
unfortunately soon lost after death by cyanide. The insects 
are gregarious, and sit in rows of from three to five each 
near the base of the stems of a shrubby herb which 
attains the height of about two feet. Sitting for the most 
part with their heads up, they cannot be said to look in 
the least like flowers, the larvae indeed look more like a 
Coccus, or even a luxuriant growth of Penicilliwm. When a 
plant harbouring the Gyariv is approached the insects Jump 
off and then fly away a short distance much like moths. 
They were only found within a very circumscribed area. 
Settled on rocks basking in what little sun was to be 
had several flies were captured, all males, of a species of 
Dichzxtometopia allied to tessellata, Macq., but probably new 
to science. 
PRETORIA, TRANSVAAL. 
Lat. 25° 53’. Altitude 4,500 feet. August 31st. 
The British Association paid a mere flying visit to the 
political capital, but this just permitted a carriage-drive to 
the Wonderboom,* which stands at the foot of the northern 
slope of a range of hills about 34 miles to the north of 
the city. So far as results were concerned the time and 
trouble, and more particularly the dust, might as well 
have been saved. Insects were very scarce save at the 
sweet-scented white flowers of Dombeya densiflora, which 
proved very attractive. There was however an incommen- 
surability between the height of the trees and the length of 
the net-stick which was tantalizing in the extreme. A 
few white butterflies were seen as well as Limnas chrysippus, 
and a Lycenid. The pedunculated wasp Belonogaster 
* A singular tree of wide-spreading growth.
