and juv. <J Nos. 3269 and 3270, Dr. W. F. Puivell and E. M. Lightfoot, 

 1*' 97). (These specimens are somewhat small in size and 1 ? appears 

 melanic. The pattern on the back, seen in spirits, is almost obliterated 

 by the presence of black pigment ; similarly with the cephalothorax ; 

 femora and tibiae of legs are darkened and have a slight olivaceous 

 tinge; under abdomen, sternum, coxae and femora are almost black; 

 spinners are dark, but with the usual dark mark on the apical segment 

 of superior spinners.) Robertson (1 $ No. 3350, Dr. W. F. Purcell, 

 11 :7), slightly melnni.-: (Mrsherg (1 ? No. 8763,0. L. Leipoldt, 

 12/00) ; Mossel Bay (1 $ No. 908, Dr. W. F. Purcell, 4/9G), also 

 melanic. 



Dwripfiiiii i if l[le. The ? ? which accompany the $ specimen 

 from Hanover do not appear separable from H. australis ; they tend 

 towards being melanic, the under abdomen heing dark or mottled and 

 with light stripes at the side, whilst the sternum and coxae are dark or 

 mottled. 



General colouring of <$ as in ? ? ; usual pattern on dorsal surface 

 of abdomen bright and distinct, the light portion being invaded by 

 darker markings ; under abdomen mottled and banded at sides ; 

 carapace and sternum mottled; legs ochreous-brown, darker towards 

 extremities, and posterior legs lightly banded. 



Leys. Longer than in ? ; 1st leg 12'5 mm. ; in ? length is about 

 10mm.; 4th leg 16 mm. ; in $ llmm. Metatarsi of 3 legs distinctly 

 curved downwards in the centre, and upwards distally ; tarsi shorter 

 and stouter than in the other legs, of which the tarsi are long and 

 slender. 



Pt'flipalps. As in fig. 9. 



In all cases it was noticed that the superior spinners of Hersiliola 

 were subecpal to the sternum in length, and that the apical lighter 

 portion tended to be conical and straight; also the tarsus of the 1st 

 leg exceeded }, the length of the metatarsus in all cases. These addi- 

 tional characters serve to separate Hersiliola from Tama, since in the 

 latter the tarsus is less than ^ the length of the metatarsus of the 1st 

 leg ; and the apical joint of the superior spinners in addition to being 

 curved and longer than the basal joint is also longer than the sternum, 

 generally equalling or exceeding the sternum and labium in length.
