Type.—1 g. (No. 4204) from Johannesburg, found by Mr. J. P. 
Cregoe. 
3g . Colour.—Carapace reddish yellow, the cephalic portion blackish 
red; chelicerze black; legs and pedipalps, including the coxe, and 
the sternum pale ochraceous ; abdomen pale yellowish below and at 
the sides, blackish brown above. 
Carapace a little more than + longer than wide, with a row of 
stout, curved, marginal spines on each side above the bases of the 
2 posterior pairs of legs, the upper surface also with a group of sete 
and sigmoid spines posteriorly. 
Ocular area about 21 times as wide as long, the sides subparallel ; 
the anterior row of eyes very slightly procurved, the lateral eyes only 
about + longer than the medians, the latter rather large, slightly 
further from one another than from the lateral eyes; the posterior row 
of eyes transverse, their anterior margins forming a slightly pro- 
curved, their posterior margins a slightly recurved line, the laterals 
as far or slightly further from the anterior lateral eyes than from the 
posterior median eyes, shorter than the former but much larger than 
the latter and about as long as the anterior medians, which are much 
larger than the posterior median eyes. 
Pedipalps unspined; the tibia long, lightly convex along the 
under side; the tarsus short, truncated; the bulb subglobular, its 
process slender, about as long as the bulb, with short spiral curve, 
the distal portion very fine and filiform, ending in a fine point. 
Legs.—All the tarsi scopulate to the base. Metatarsus of first 
leg much slenderer than the tibia, ightly concave internally, equal
