kindly promised to describe. [Plate II., Fig. 10.] Microthrix insulsella, 
two: a dingy Phycid. Etiella zinckenella, one: an almost cosmo¬ 
politan Phycid. Also several other small moths not yet determined. 
Nehroptera. — Nemopistha (Halter) lancearia, Navas. Three 
specimens of this very singular insect came to the lamps; its very 
long, slender and spirally twisted hind-wings seem to suggest a 
flying machine rather than an insect. 1 Father L. Navas has recently 
described this from a fragmentary specimen in the British Museum. 2 
[See Plate II., Fig. 2.] (?) Oestropis sp., and (?) Blymorphanismus sp., 
two green Triclioptera, together with other Caddis-fiies more like 
European forms. 
Orthoptera. —A Cricket. 
Hemiptera. — Acanthaspis nugax , Stal, a Reduviid bug with a 
peculiar fetor. 
Coleoptera. — Apate monacha, Fabr., two $. Himatismus sp., 
three: not in the British Museum. Trochalus sp., one: in the 
National Collection, unnamed. Xylopertha sp., one. Two Longi- 
corns, Plocederus melancholicus , Gahan, and Tetradia lophoptera , Guer. 
( fasciaticollis , Thomps.), also came to light; the latter was captured 
by one of us on his bed, clinging closely to the sheet, and making a 
curious creaking noise when disturbed. 3 
Lastly a male Acraea alboradiata was taken fluttering on the 
floor below an electric light at 9 p.m.! 
While one of us was busy with the electric lights a waiter 
excitedly called out that there was a “ Tarantula ” under the stoep. 
He was most anxious that it should be secured, but declared that 
its bite was deadly. It proved very fleet of foot and doubled like 
a hare; other waiters joined in the chase, which proved most exciting, 
especially when the spider ran over the neck of the ardent entom¬ 
ologist. When the fierce creature yielded at last to the soothing 
influence of cyanide it was seen to be of a pale reddish-brown, with 
pale grey abdomen, but armed with most formidable-looking red- 
brown mandibles, tipped with black. Black eyes added to its 
ferocious aspect. Ultimately a second specimen was bottled— 
together with one of another species. 
Above the Falls the Right Bank of the river (here the south¬ 
western) was the most readily accessible collecting ground, and 
perhaps for that reason received an undue amount of attention. There

comparison still seems to me to bold good.
