yellow lines separating them narrow, straight, and parallel, passing 

 anteriorly round the median eye-tubercle, the median stripe well 

 developed, reaching highest part of dorsal surface, the lateral stripes 

 broad and provided each with 2 more or less distinct yellowish spots 

 near the middle ; sides of carapace with a series of black-bordered 

 spaces in 1 or 2 tiers. Sternum with 4 marginal infuscate marks on 

 each side and a few more central dots. Abdomen with transverse 

 black bands and rows of spots. Femora of legs infuscate at apex 

 and sometimes faintly so nearer the middle, the anterior pair faintly 

 infuscate along anterior and posterior surfaces ; patellae infuscate, 

 pallid above ; tibiae darkened at apex and often also at base. 



Palpal organ a little longer than the tarsus, which is about equal 

 to the process in length ; the process broadened distally, with a 

 strong brownish keel on inner side, the short apical portion with 

 very strong sigmoid curvature (PI. X., fig. 23). 



Length of trunk 5 mm.

* The only other South African species which have been described are S. broomi 

 from Namaqualand and S. marshalli from Estcourt (Pocock, Ann. Mag. N. H., 

 ser. 7, vol. x., pp. 321-323, 1902). Both are unknown to me.
