South African Arachnida. 163 



Tergites 1-6 densely and finely granular in the anterior, more 

 coarsely granular in the posterior parts of the segments, segment 7 

 finely shagreened mesially between the inner keels, coarsely granular 

 laterally. 



Sternites as in the ? of capcnsis, the last segment granular 

 laterally. 



Tail stout, sparsely pilose ; segments 1-4 subequal, or segments 

 1-3 increasing successively but very slightly in width, segment 4 

 slightly wider than segment 1 ; segment 5 high, segment 1 nearly as 

 high as segment 4 but higher than segment 5 ; vesicle large, its 

 width i that of fifth segment. 



Segments 1-4 with 10 very strong, coarsely granular crests, the 

 infero-median crests smooth anteriorly in segment 1 but abbreviated 

 or irregular posteriorly in segment 4, the middle lateral crest in 

 segment 4 strong. Superior crests in segments 2-3 with an enlarged, 

 sharply pointed, subspiniform, posterior tooth ; these crests in 

 segment 4 dislocated or more or less distinctly doubled in the middle, 

 2 or 3 of the posterior teeth much enlarged and subspiniform ; 

 superior crests in segment 5 as in villosus, distinct and strongly 

 developed throughout, the accessory superior crest very conspicuous, 

 . composed of 2-3 very large, subspiniform, posterior teeth and 1-2 

 smaller anterior ones. Infero-lateral crests of segment 5 with 1 or 2 

 of the posterior teeth somewhat enlarged and lobe-like. 



Upper surface in anterior segments somewhat reticularly granular 

 laterally, densely shagreened mesially. Segment 1 less flat above 

 than in villosus, lightly hollowed out from side to side, especially 

 posteriorly, shallowly grooved mesially almost as deeply as in 

 segments 2-4 ; the upper surface longer than wide in the middle ; 

 the superior crests distinctly converging posteriorly ; the shagreened 

 area moderately large, lightly concave throughout its length, which is 

 about 2|^-2f times its greatest width, the latter occupying about f of 

 the width of the upper surface ; posteriorly the shagreened area is 

 slightly constricted, then widened again, its anterior edge is narrow, 

 and the upper surface descends less abruptly than in capensis and 

 not quite perpendicularly. Segment 2 grooved mesially above 

 throughout its length as deeply as in segments 3 and 4 ; the upper 

 surface as long as or slightly longer than wide in its middle ; the 

 superior crests almost parallel ; the shagreened area occupying the 

 groove, almost as large as in segment 1 and similar in outline, reach- 

 ing hind edge of the segment, its length 2|— 2f times its width, which 

 at the widest part occupies about f of that of the upper surface ; 

 anterior edge as in segment 1. The superior groove finely granular
