entirely covered with white hairs (replaced occasionally by black 

 ones), and bordered on each side by a band of white (rarely yellow) 

 hairs. Chelicera nearly black, covered with white hairs, except 

 quite at apex, where the hairs are black. Sternum pale yellow or 

 reddish-yellow, the sides broadly blackened, the hairs white, with a 

 few black setae. Legs pale yellowish, the 2 anterior pairs more 

 reddish, all very strongly banded with black, the femora with a 

 broad, intensely black, apical band, and one or two paler ones near 

 the base, tarsi and metatarsi of 2 anterior pairs often darkened, the 

 base of the metatarsi then yellowish or reddish-yellow ; all or most 

 of the coxae and trochanters with black patches ; the hairs on the 

 legs white, those on some of the black bands black. Abdomen pale 

 yellow, covered for the most part with yellow or cream-coloured 

 hairs, without spots above, excepting the stigmata and generally also 

 a few tiny black spots or groups of black setae ; the sides with a 

 number of black spots and an inferior black patch (with black hairs) ; 

 under surface with 2 large roundish or oval yellow marks posterior 

 to the 2 pulmonary spiracles, and separated by a broad median 

 black band, which is cleft anteriorly and clothed with black hairs ; 

 epigastric area black in the middle but yellow on the pulmonary 

 opercula, these again often narrowly encircled with black, the hairs 

 (except those immediately round the vulva) white ; spinners black. 



Carapace longer than patella and tibia and as long as the tibia and 

 f , or nearly the whole of the metatarsus of first leg. Eyes much as 

 in S. canus, n. sp., except that the anterior row of median eyes is 

 wider, being not much narrower than the second row. 



Vulva with the edge of the large cavity deeply emarginated in 

 front, the cavity with a median keel and bounded behind by a curved 

 ridge, which is notched in the middle ; hind margin of the plate of 

 vulva convexly projecting backwards beyond the hind margin of the 

 epigastric area on each side of it (PI. X., fig. 6). 



$ $ . Colour. — Carapace much less densely hoary, often with 

 some yellow hairs on each side on thoracic portion and yellowish- 

 brown ones on the face ; abdomen clothed above and on the upper 

 part of the sides with rusty-red or brownish hairs, but the middle of 

 the dorsal surface with a large, fusiform median band of pallid hairs; 

 2 anterior pairs of legs much less intensely banded, the bands being 

 obsolete or almost so on the tibia above. 



Carapace with the cephalic portion much higher and more abruptly 

 defined, its length equal to the tibia and 7 V-J of the metatarsus of 

 first leg. 



Legs much longer, especially the anterior pair ; tibia of first leg 

 without fringe of long hairs, but the proximal black band clothed
