Palpal organ with the spine stoutish, blunt at the apex, 

 with a conspicuous crest or keel just above it. 



$ . — Colour the same as in the male ; clypeus about half 

 as long as the tubercle ; carapace at least as long as patella 

 and tibia of first and fourth legs, a little shorter tlian tarsus and 

 protarsus of fourth, the width equal to the patella and tibia of 

 the second, equal to the fourth protarsus and half the tarsus ; 

 length from fovea to anterior margin a little less than fourth 

 protarsus and than patella and tibia of third leg. 



Measurements 171 millhnetres. — ^. Total length 19; length 

 of carapace 10, width 8 ; length of first leg 28*5, of second 

 26, of third 25, of fourth 32 ; patella and tibia of first 10-2, 

 of fourth 10 ; protarsus of fourth 8"8. 



?. Total length 26; length of carapace 11'5, width 9"5; 

 length of first leg 28'5, of second 26"5j of fourth 32 ; patella

Loc. Barberton, Transvaal [Percy Rendall). 



This species may be recognized as follows from the only- 

 other male of the genus known : — 



a. Of small size (carap. 10 mm.) ; protarsus of first 



leg straight ; carapace uot longer than patella, 

 tibia, and tarsus of palp ; spine of palpal organ 

 with a strong upstanding crest and a blunt point, nigrofulvus, sp. n. 



b. Of large size (curap. 16 mm.) ; protarsus of first 



leg basally sinuate ; carapace much longer than 

 patella, tibia, and tarsus of palp ; spine of palpal 

 organ simple and attenuate vorax, Poc. 



The females of the three species in which this sex is known 

 may be distinguished as follows : — 



a. Ocular tubercle rounder, uot very much wider than 



long, and sepai'ated from the edge of the carapace 

 by a space equalling quite half its length. 

 a\ Carapace longer than patella and tibia and than 



tarsus and protarsus of fourth, almo.-t as long 



as tibia, protarsus, and tarsus of third leg; 



length from fovea to anterior border greater 



than fourth protarsus vorax, Poc. 



6'. Carapace as long as patella and tibia of fourth, 



shorter tlian tai-sus and protarsus of fourth and 



than tibia, protarsus, and tarsus of third leg; 



length from fovea to anterior border less than 



fourth protarsus nigrofulmis, sp. n. 



b. Ocular tubercle more transversely elongate, the 



clypeus less than half it^ length (carapace and 

 leg-measurements as under i') vutritius, Poc.
