23O W. F. PURCELL, 28 
5. Afiadna pulchripes n. sp. 
I $ from Rooibank near Walfishbay, Southern Hereroland, May 1905. 
Allied to A. bilineata and karrooica Purc. (Trans. S. Afr. Phil. Soc, Vol. XV, p. 15g, [904;. 
Colour. Cephalothorax almost black ; abdomen black above the lateral line, paler below it, the 
lung-opercula pale-yellow; femora and tibiae deeply blackened and without yellow stripes in the two anterior 
pairs of legs, less deeply blackened and with the usual yellowish stripes in the two posterior pairs ; patellae 
pale-yellow, lightly infuscated on the sides, the two anterior pairs more deeply blackened on the inner 
side ; metatarsi I and II blackened above, paler below, III and IV pale-yellowish, only slightly infuscated 
and much lighter than the tibiae ; anterior tarsi infuscated, posterior tarsi pale-yellowish ; anterior coxae more 
infuscated than the posterior ones, all much paler than the blackened sternum. Whole body covered with 
black hairs. 
Cephalothorax as long as the tibia and 2 / s of the metatarsus of first leg, considerably narrowed 
in front, its width just behind the ocular area scarcely 2 / 3 of the length of the first tibia. Ocular area 
tolerably wide, the distance between the posterior lateral eyes and the medians only very slightly less than 
the united width of the latter. 
Legs clothed with intensely black hairs, the hairs on the first leg numerous and fairly long. Tibia 
of first leg wide, wider than the distance between the posterior lateral eyes. Metatarsus I a little shorter 
than the tibia ; II with an inner basal spine above the inner inferior row ; III with 3 superior spines on 
inner surface, none on outer surface and two rows on the under surface, the outer inferior row consisting ot 
an apical spine and a group of 3 — 5 spines close together but remote from the apical spine ; IV with 4 
inferior spines and with 6 — 7 setae in the apical comb. Tibia I with 5 — 6 spines in each inferior row, the 
outer surface besides with 5 and the inner surface with 3 — 4 other spines ; II with 3 spines on each side 
above the inferior rows; III with an inferior row of 3 and a superior inner row of 2 spines; IV unspined. 
Patellae not spined. Femora II and III with no outer distal spine, IV with an inner distal spine and 
several stout upper setiform spines near base, the femur otherwise as in A. bilineata Purc. 
Chelicera with 3 small superior teeth and a minute apical inferior tooth. 
Length of cephalothorax + abdomen 12 mm. 
6. AHadna similis n. sp. 
1 ? from Mafeking, Bechuanaland, February 1905. 
Closely allied to A. bilineata Purc. but larger, coloured as in the darker specimens of bilineata, except 
that the superior yellow stripes on the posterior tibia are coalesced to a broad band and the sternum is 
infuscated. 
Cephalothorax as long as the tibia together with over 1 / 2 but less than 2 / 3 (about 7 /i 2 ) of the 
metatarsus of first leg, its width just behind the eyes about 2 / H of the length of the first tibia, the latter 
scarcely wider than the distance between the posterior lateral eyes. 
Legs. Metatarsus II with an inner basal spine above the inner inferior row, III with 2 inferior 
rows of spines and 1 anterior upper spine (but none on posterior surface). Tibia I with 5—6 spines in 
each inferior row, III with a single (inferior) row of spines only. 
Length of cephalothorax + abdomen II 1 /* mm - 
Dr. Schultze also collected 4 very young examples of Ariadna from Steinkopf, Little Namaqualand, 
and on the road between Khakhea and Kang, Kalahari, Bechuanaland Protectorate.
