Originally described as a distinct species, it was afterwards regarded by 
Pocock only as a variety of lineatus (7), but is held to be a good species by 
Purcell (17).

Distribution : The types came from the summit of the Grreat Winterhoek, 
Tulbagh Division. 
The British Museum has a specimen (PL XXX fig. 21) without locality 
data, which seems referable to this species, under the manuscript name of 
Z7. kraejjelini, Pocock ; in that specimen, the upper surface of caudal seg- 
ment I is only very faintly granular ; the superior keels of caudal segment I, 
as well as II and III, terminate in low stout blunt tubercles ; total length 
45" 5 mm.

Distribution : According to Kraepeliu, this species extends from Delagoa 
Bay into the Transvaal, Bechuanaland Protectorate, western Kalahari, 
Damaraland and Ovamboland. We have a series of specimens from Serowe 
(S. Blackbeard), from M'moove, 42 miles north of Serowe (S. Schonland) 
and from Newington (J. P. Fenoulhet). The Transvaal Museum has it 
from Pretoria, Hectorspruit and from Yygeboompoort (Waterberg District.) 
Kraepelin (10) has recorded the related species occidentalis E. Sim., from 
Natal, but that species is not otherwise kn@wn from S. Africa, and I think 
the record is probably incorrect ; in a more recent paper (Mit. a. d. Nat. 
Mus. Hamburg, xxx, p. 177, 1913) he only cites ' Kamerun to the Congo' 
for the African records. According to the same authority, the East 
Transvaal species, IT. jutrzenkai Penther (26), is a synonym of vittatus ; but 
for Kraepelin's statement, I should have suspected t\idii jutrzenkai d^iidL chuhbi 
are synonymous.

Distribution : The type came from Otjimbingue, and the species is known 
to Kraepelin from Damaraland and Hereroland. 
The species is unknown to me, but judging from the description it would 
seem to be scarcely more than a colour-variety of vittatus.

No. 2, p. 5, 1911. 
Distribution : The precise locality of the type is unknown, but was 
labelled Ehodesia ; we have it from Tsessebe Siding, Tati (E. C. Wilmot). 
This species, as stated by Mr. Hirst, is evidently closely related to Z7, 
xanthogrammusVoa ; according to Kraepelin (Mit. a. d. Nat. Mus. Hamburg,
