$? Colour. Cephalothorax reddish, the cephalic portion blackened on the sides and behind (except 
<>n the 2 posterior red areas), the thoracic portion also more or less infuscated in the middle but broadly 
yellowish or reddish-yellow at the sides and behind, the margins not at all or only partially blackened. 
Surface covered with white hairs, except on the ocular area, which is covered with yellow hairs, those on 
the face forming a large triangulär patch bisected down the middle and bordered all round by narrow stripes 
of white hairs, those behind forming an oblique area on each side separated by a broad median band of 
white hairs, each again partially divided by a narrow band of white hairs running longitudinally from a 
posterior lateral eye to meet the transverse white stripe in front of it. Chelicera reddish at the base, black 
distally, the basal part covered with white hairs, the distal part with black ones. Sternum broadly blackened 
on each side, except quite behind, the median yellow area widening cohsiderably behind, the hair-covering 
white, with a few small lateral spots of yellow hairs. Legs pale-yellowish, the two anterior pairs reddish at 
the distal ends only, all feebly banded with black, the bands like those of S. tentoriicola Purc. (Trans. S. 
Afr. Phil. Soc, Vol. XV, p. 135, 1904) but much paler, the hairs white, those on some of the black bands 
black. Abdomen pale-yellow, the long lanceolate median area on the dorsal surface without or with only 
a few minute black spots but bordered on each side by the row of blackened Stigmata and other black 
markings, the sides of the abdomen, the anterior surface and often, also, the anterior part of the upper 
surface spotted and marked with black (except along the median area) ; under surface blackened (except on 
the opercula) on a pair of broad longitudinal bands (diverging posteriorly) behind the opercula and on a 
few other tiny spots, which are yellowish. Hair-covering of abdomen composed of yellow and white hairs, 
the yellow predominating in the posterior parts, the white in the anterior parts and along the median dorsal 
area, the posterior portion of which is provided with 4 — 6 pairs of short transverse branchlets, composed ot 
white hairs; under surface with some dark hairs on the black patches, especially round the anterior edge of 
the vulva, the anterior part of the black area between the opercula, and the 4 large yellow areas covered 
with white hairs, as well as several small dots on the posterior black patch. Spinners with black hairs. 
Cephalothorax and eyes as in S. tentoriicola Purc. (Trans. S. Afr. Phil. Soc, Vol. XV, 
p. 135, 1904). 
Vulva (PI. XI, Fig. 5) very like that of S. tentoriicola (loc. cit, pl. 10, flg. 6), but the median keel 
is continued to the end of the tongue-like projection and is enlarged in the middle and flanked posteriorly 
by a pair of short oblique keels. The shape of the enlarged part varies but is more or less distinctly 
cruciform, while the 2 posterior keels also vary somewhat in direction, being sometimes more longitudinal, 
sometimes more transverse than in the figure, and sometimes even uniting with the posterior end of the 
median keel to form a semicircular crest. 
66 Colour. Cephalothorax red at the sides and posterior part of thoracic portion as well. First 
leg with the coxa, trochanter and femur 3'ellowish-red, the patella and tibia and the 3 other pairs of legs 
also more reddish-yellow than in the ?, especially on the darker bands. Abdomen with the area of yellow 
hairs on each side of the lanceolate median area reaching forwards right to anterior end of the dorsal 
surface. Sternum redder. 
Cephalothorax much more abruptly defined in the cephalic region ; its length *) equal to that of 
the tibia and about 1 j 3 of the metatarsus of first leg. 
Legs. The two anterior pairs relatively a little longer than in the ?; tibia of lirst pair neither 
fringed below nor minutely spinulose on the black bands.
