Plate 6, fig. 4-10; Plate 7, fig. 1-2. 
Integument of carapace, chelicerae, femora of legs and palpi, 
sternum and labium dark chocolate-brown, the other parts of legs 
and palpi lighter brown, in part of dilute reddish tinge; sternum and 
femora of legs beneath sometimes lighter than above. Integument 
of abdomen brown, paler beneath than above; above with a small 
light area toward anterior end. Carapace covered with a woolly coat 
of russet-brown hair of a more or less coppery lustre, and some longer 
grey ones at caudal edge especially. The legs are thickly clothed 
with short brownish hairs with deep black ones more sparsely inter- 
mixed; the numerous longer bristles are dark proximally, becoming 
grey, grey or white distad, these forming rather indistinct longitudi- 
nal streaks on the femora and patellae. Abdomen densely clothed 
with brown hair of a distinctly coppery lustre, that of anterior surface 
black and forming a distinct black area; longer bristles of dorsal 
surface grey distally; sometimes dark hairs form a larger element on 
the ventral surface and this surface then appears dark grey or blackish 
instead of copper-brown as more usual. Fringes of endites and cheli- 
cerae orange proximally, lighter distad. 
Eye-tubercle sharply limited; of moderate height. Eye-area less 
than twice as wide as long in both male and female (67:37); rows 
subequal or the posterior one slightly longer than the anterior (up to 
ratio 67:65). Anterior row of eyes in dorsal view a little procurved; 
in anterior view rather strongly procurved. Anterior median eyes 
with diameter not much more than half that of the laterals (cir. 6:11), 
a little more than their radius apart, but decidedly less than their 
radius from the laterals. Posterior row of eyes conspicuously re- 
curved. Posterior laterals smaller than the anterior laterals from 
which separated by less than their radius. Posterior medians three 
fourths the diameter of the laterals; mesal side more curved than the 
ectal, more or less angulate anteroectally, (Plate 6, fig. 4). 
Head low, only slightly rising in front of the thoracic groove;
