XXX, p. 177, 1913), that species should only rank as a variety of fischeri 
Karsch, in which case chuhhi also should be assigned varietal importance. 
In our specimen, a female, all the caudal segments, except the first, have 
the position of the superior keels marked by very coarse puncturations ; in 
the first caudal segment the position of the superior keels is marked by 
granules, but they do not form a very distinct keel ; the vesicle inferiorly 
and laterally is coarsely and closely punctate, but not so coarsely as on the 
caudal segments.

Distribution : A very common species in the Cape Province, Transvaal, 
Free State, and Basutoland (see Purcell 17, Pocock 7). Apparently, it is 
absent from G-erman South-West Africa, from the greater portion of Natal, 
and from the south-west portion of Cape Province. The form described by 
Pocock under the name of U. marshaUi was recorded from Durban, but 
perhaps erroneously so. 
We have this species from Glrahamstown, Alicedale (F. Cruden), Duu- 
brody (Fr. Vogt), Keilands (Trappist Bros.), Steytlerville (Miss A. G-eard), 
Mimosa (Prof. Schwarz), Redhouse (Mrs. T. V. Paterson), Ann Shaw (F. S. 
Salisbury), Klerksdale near Middelburg (B. Marais), Conway (J. Hewitt), 
Fish River Randt (Mrs. Gr. White), Burghersdorp (Dr. Broom), Bloemfontein 
(Dr. T. F. Dreyer), Doornkop near Belfast (R. Grerhardt), Kroonstad (Miss 
D. Chennells), Pienaars River, Pretoria (Gr. van Dam), Zandfontein, Rusten- 
burg district (Gr. van Dam), and Hornsnek (Gr. van Dam), Kimberley (Bro. 
J. H. Power), Standerton (Durban Museum), Weenen (H. L. Bulcock). 
The Transvaal Museum has it from Carolina, Woodbush, Munich's Farm 
near Pietersburg, Lochiel (Ermelo district), Clearwaters near Haenertsburg,. 
and Yygeboompoort (Water berg District). 
This species is somewhat variable, and eventually it may even seem 
desirable to include U. olivaceus Pocock as one of its varieties ; at any rate 
the only satisfactory point of difference between the two species is found in 
the shape of the vesicle of the adult male. 
Two chief colour- varieties are recognised by Dr. Purcell (17). TJ\ 
triangulifer var. typicus has each of the tergites fuscous, with three rather wide 
longitudinal yellow stripes, one median and two lateral, and a large >- 
shaped yellow mark on each side of the median stripe. In this form the 
basal pectinal tooth of the female may or may not be somewhat enlarged. 
It is slightly broadened and obtusely rounded at the apex in all our Trans- 
vaal examples, but is unmodified in specimens from the Cape and Free State. 
The tergites are granulated throughout. Z7. triangulifer var. tristis Thorell, 
recorded by Purcell from the Eastern Transvaal, is characterised by the 
blackish colouration of the trunk, the yellow markings being absent except
