a s . Distal patch of spinules on tibia I large, extending over 

 J-J of the length of the dorsal surface ; metatarsus III 

 with 13-22 spines in the anterior and 22-34 in the pos- 

 terior band ; posterior lateral eyes much larger than the

I s . Distal patch of spinules on tibia I small, extending over

 tarsus III with 12-21 spines in the anterior and 14-24 in 

 the posterior band. 



9 . Posterior lateral eyes much larger than the posterior 

 medians; length of tibia I equalling or slightly ex- 

 ceeding (rarely slightly less than) the width of the 

 posterior row of eyes. Montagu 



S. qiiadratimaculatus n. sp. 



I 9 . Posterior lateral eyes small, subequal to or only slightly

 less than the width of posterior row of eyes (often 

 considerably less). Swellendam and Robertson Divi- 

 sions K. breripalpis n. sp. 



b 6 . Tibia of first leg slightly longer than the metatarsus ; posterior

o". Metatarsus IV spined along the middle below. Port Eliza- 

 beth S. castaneus n. sp. 



6". Metatarsus IV without spines along the middle below (except

a". Length of tibia I subequal to or less than the width of 

 the ocular area ; all the setiform spines of apical tuft of 

 metatarsus IV crowded into a transverse row. Pear- 

 ston * S. (istittus Poc. 



b 12 . Length of tibia I very distinctly exceeding the width of 

 the ocular area ; only the inner setiform spines of apical
