about ^ the width of the upper surface ; posteriorly the shagreened 

 area is constricted, and then sHghtly widened again at the hind 

 margin ; at its anterior edge the surface descends, as in transvaalicuSf 

 less abruptly than in capensis and not quite perpendicularly. 

 Segment 2 with a moderately large oval excavation occupying only 

 the anterior half of the upper surface, the posterior half of which 

 is shallowly grooved along the middle and quite smooth ; the 

 shagreened area small, confined to the anterior concavity, about 

 twice as long as wide, its length only half, its width ^-J times, that 

 of the upper surface. Segment 3 grooved mesially above, the 

 anterior half of the groove deeper and finely granular. Segments 4 

 and 5 grooved mesially, the groove smooth in segment 5, weakly 

 and very finely granular or almost smooth in segment 4 and not 

 bordered on each side by coarser granules. 



Lateral surface in segment 1 granular in its upper part, the 

 inferior surface of this segment smooth or nearly so between the 

 keels ; segments 2-3 almost smooth on the sides between the keels- 

 or provided with a few coarse granules (occasionally with some very 

 minute and weak reticular granulation in addition), the inferior 

 surface, however, generally more thickly granular between the 

 median keels ; segment 4 coarsely and rather thickly granular below, 

 more sparsely granular, sometimes almost smooth, on the sides ; 

 segment 5 thickly covered below with fine and coarse granules, the 

 median crest distinct, regularly uniseriate or irregularly granular, 

 the accessory crests indistinct or partially developed ; sides of the 

 fifth segment sparsely and coarsely granular in the lower part but 

 generally nearly smooth in the upper part, the surface sometimes 

 with a very minute granulation in addition to the coarse granules. 

 Vesicle coarsely and seriately granular below. 



Pedvpalps. — Femur finely granular above. Tibia finely granular 

 above, the anterior crest of upper surface mostly distinct and well 

 developed, sometimes weak and irregular, the length of tibia along 

 upper side in the ? 2?, in the ad. ^ 2i- times its width. Hand 

 slender in the 5 and juv. <? , its width slightly less than that of 

 the tibia, but stout and exceeding the tibia in width (by about i-i) 

 in the ad. S^ ; length of movable finger in ? 2i-2f , in ad. ^ If-lif 

 times that of hand-back ; movable finger with generally 14 but 

 often with 15 anterior flanking teeth, the main rows in the 

 middle third of the fingers with 5-8 teeth (including the enlarged 

 basal tooth of each row). 



Legs with the femora thickly and the tibiae weakly granular 

 externally.
