Fahr.; also a Lady-bird, Exochomus nigromaculatus, Goze, which is 
occasionally found in Britain. 
Under stones were two Pentatomid bugs, Dalsira modesta, Fabr., 
and the lance-head-shaped Gonopsis angularis, Dali., also Lygaeus 
rivularis , Germ.; there were also several other bugs that are not yet 
named. Along with the bugs were several Cockroaches and a black 
and red Scorpion. Two specimens of Acridium pardalinum, Walk., 
and a number of as yet undetermined Acridians were also taken. 
The most interesting insect met with at Johannesburg was a 
Homopteron, Gyaria walheri, 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, that 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; immature 
specimens look more like a Coccus, or even a luxuriant growth of 
Penicillium. When a plant harbouring the Gyariae is approached 
the insects jump off and fly away a short distance much like moths. 
They were only found within a very circumscribed area. 1 
Settled on rocks basking in what little sun was to be had several 
Flies were captured, all males, of a species of Dichaetometopia allied 
to tessellata , Macq., but probably new to science.

The British Association paid a mere flying visit to the political 
capital, but this just permitted a carriage-drive to the Wonderboom, 
a singular tree of wide-spreading growth, which stands at the foot 
of the northern slope of a range of hills about 3J 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 
spared. Insects were very scarce save at the sweet-scented white 
flowers of Dombeya densiflora [Hat. Ord. Sterculiaceae ] which proved 
very attractive. There was, however, an incommensurability between 
the height of the trees and the length of the net-stick which was 
tantalizing in the extreme. A few Whites as well as Danaida chrys- 
ippus and a Lycaenid were seen out of reach. The pedunculated
