Palpal organ large, its exposed portion composed for the most part of a strongly inflated, subspherical, 
white, membranous bulb, which is wider than the tarsus and bears on its distal side a large separate claw- 
shaped piece of brown chitin, the basal part of this claw being large and broad and in contact with the apex 
of the tarsus or almost so, the apical portion curving backwards, downwards and outwards and rather blunt.

I $ from Kamaggas, Little Namaqualand, July 1904. 
Colour and markings very much as in P. reticulatus E. Sim. (Bull. Soc. Ent. Fr., 1902, p. 243) from 
the Cape Peninsula, but with the legs much more strongly banded with black below on the femora, patellae, 
and tibiae, the metatarsi only indistinctly banded. 
Ocular area broader than in reticulatus, the posterior row of eyes being much straighter and only 
slightly procurved, the median eyes very slightly nearer to the laterals than to one another, the anterior 
row of eyes lightly procurved, a little narrower than the posterior row; all the eyes subequal. 
Legs normal; metatarsus I a little shorter than the tibia. 
Pedipalps with 2 spines on upperside of femur and 1 setiform spine at apex of patella above, as 
in P. reticulatus^); femur and patella as in P. reticulatus; the tibia, however, much shorter and broader, its 
length along its axis (apart from the spur) being slightly less than that of the patella, its upper and inner 
surfaces lightly convex, its outer surface much distended laterally commencing gradually from the base, the 
segment being widest in the distal third where its width is subequal to its length along the axis, the 
distended portion produced outwards and forwards beyond the level of the point of insertion of the tarsus 
and terminating in a pair of spurs with a J-shaped narrow sinus between them, the inner spur being longer 
than the outer one, sharp and curved; patella and tibia together shorter than the femur; tarsus slightly 
longer than the patella and tibia (exclusive of the spur) together ; palpal organ composed of a convex bulb 
occupying the greater portion of the underside of the tarsus and provided at its distal end with 2 small, 
curved, black, spinous processes, just above which the apex of a slender style protrudes (PI. XI, Fig. 4). 
Chelicera with 4 — 5 denticles in the lower row. 
Length 4 1 /,, mm. 
Although the posterior row of eyes is much less strongly procurved than in the typical species, 
P. reticulatus, this new species is nevertheless closely related to the latter and has the same broadly 
truncated sternum and similarly shaped mouth-parts, the short labium not reaching beyond the middle of the 
coxae of the pedipalps.

1) The spine on the upper inner edge of the tibia, present in P. reticulatus, is absent, but it has probably been broken 
off, as its position is marked on each tibia by a scar.
