20 Mr. R. I. Pocock on some neio 



Eyes of tlie anterior line subequal, medians barely a 

 diameter apart and about three diameters from the laterals ; 

 posterior medians small, smaller than anterior medians, about 

 four diameters apart and nearly six diameters from the poste- 

 rior laterals. 



Mandibles armed below with two strongish teeth. 



Legs bristly, more thickly hairy distally, the tarsi and 

 protarsi of the anterior pairs lightly scopulate beneath, the 

 bristles on the base of the legs on the upperside spiniform. 



Area of vulva with a median T-shaped horny plate, the 

 upright of the T pointed at the bottom, each half of the cross- 

 bar lightly arched and curled backwards at the extremity, 

 circumscribing a shallow, irregularly transversely oval de- 

 pression. 



^ . — Like the female in colour. Legs longer. Palpus 

 with patella and tibia short ; tarsus large and inflated, 

 furnished with a long filiform flagellum and below with a 

 forwardly-directed spine ending in a small apical hook. 



Measurements in millhnetres. — ? . Total length ll'S; length 

 of carapace A'b, width 3*8 ; first leg 12'5, second 15, third 13, 

 fourth 14. 



^ . Length of carapace 3*5 ; length of first leg 14, of 

 second 16, of third 13, of fourth 14'5. 



Log. Tea Fountain, near Grahamstown {Miss Leppan^. 



Differs from the foregoing and from P. laterigradus and 

 pusillus in colour, in having two mandibular teeth, and in the 

 form of the vulva. 



Apart from their coloration, the four South-African species 

 of this genus known to me may be distinguished as follows : — 



a. Legs very smootli, without bristles or long hairs, clothed 

 with short downy hair ; protarsi and tarsi of fii'st and 



second pairs with scopula of clavate hairs pictus, sp. n. 



h. Legs furnished with long bristles. 



(i^. Eyes of anterior line not very unequally spaced, 

 distance between median and lateral a little more 

 than the diameter of the median ; tibia and pro- 

 tarsus of first leg spined below pusillus, Poc. 



b"^. Eyes of anterior line very unequally spaced, distance 

 between median and lateral at least twice the 

 diameter of the median ; no spines, only bristles on 

 the tibia and protarsus of first leg. 

 a^. Tibia and protarsus of first and second leg with 

 short scopula of clavate bristles ; distance be- 

 tween median and lateral eye on each side about [Poc. 



twice the diameter of the median laterigrad-us, 



h^. Tibia and protarsus of first and second leg vrithout 

 scopula ; distance between median and lateral eye 

 on each side about three times the diameter of [sp. n. 



the median Leppana,
