example from Queeustown which closely approaches the jpugnax condition. 
The last sternite in that specimen has rather large and smooth granules in 
its mesial portion, the granules being disposed in few rows. There is no 
coarse granulation on the penultimate sternite such as occurs in Pretoria 
specimens of pugnax ; the inf eromedian keels of caudal segment I are not 
definitely granular, but coarsely and irregularly pitted ; the interocular area 
is densely granulated ; pectinal teeth 16. In a male example from Pearston 
the last sternite is coarsely granulated, but the granules are much more 
numerous than in the Queenstown male. 
Specimens from Jansenville in our collection have the following char- 
acters : Female, hand only slightly convex above and the ridges so low that 
the surface is nearly smooth, last sternite quite smooth mesially, infero- 
median keels of first caudal segment pitted but not crenulated, interocular 
area quite smooth throughout, pectinal teeth 16. Male, last sternite without 
granules mesially but with low transverse ridges, hand above beset with 
rather fine granules, pectinal teeth 19. It is much paler than the ordinary 
form of latimanus, the legs being yellow. 
The shape and granulation of the hand in adult males is somewhat 
variable, and on this account I regard austeroides as only a form of latimanus 
rather than a distinct species. 
O. latimanus var. pugnax Thor. (PI. XXIII, figs. 41, 45, and PI. XXVII, 
%. 75). 
Distribution: Thorell's type (1) came from " Caffraria " and the form 
seems to be characteristic of the higher parts of the Transvaal, Free State 
and Basutoland. We have it from Pretoria (Gr. van Dam) and from 
Hornsnek. The British Museum has specimens from Basutoland and from 
Kuruman. 
The Transvaal Museum has this species from the following localities : 
Pretoria District : Eosslyn, Wondeboom, Groedgedacht, Mayville, Koedoes- 
poort, Hornsnek, Sjambokstad, Eobert's Heights, Quaggas Poort, Water kloof, 
Garstfontein, De Kroon, Zoo Gardens, Mooiplaats, Derdepoort. Eustenburg 
District : Eustenburg, Groenkloof , Zandfontein. Potchefstroom District : 
Priederikstad. Newcastle District: Boscobello. — Witwatersrand : Eiet- 
fontein (near Johannesburg). — Heidelberg District : Yereeniging. 
This form is unknown to me from Eastern Cape Province. 
The average number of pectinal teeth in pugnax is rather less than in 
typicus, but the two forms cannot be sharply separated on this character. 
The first 6 tergites are usually thickly granular throughout. The first 
4 sternites of the male are often transversely wrinkled mesially, especially 
on the third and fourth sternites, the first being sometimes practically 
smooth and the second only weakly wrinkled ; on the fourth sternite there 
is a tendency for the transverse ridges to break up into more or less distinct
