caudad down posterior declivity of cephalothorax; lateral borders also 
black, the lateral bands confluent with the median one in front; cly- 
peal margin pale. Sternum testaceous, broadly bordered with black. 
Labium and endites blackish. Chelicerae testaceous in front, darker, 
chestnut, distally. Legs black, conspicuously annulate with yellow or 
testaceous; femora with a broad light band proximally and a narrower 
one toward distal end; patellae with one subdistal annulus; tibiae 
with an annulus at proximal end and one between middle and distal 
end; metatarsi with annuli corresponding to those of tibiae; tarsi en- 
tirely light or light at the ends. Abdomen black; on dorsum toward 
caudal end in median line a row of three small light dots and in front of 
these two pairs of separated oblique light marks of which the anterior 
send a slender branch forward. Hairs of abdomen short, numerous. 
Posterior row of eyes a little procurved; median eyes only slightly 
elongate and oblique, about seven tenths their longer diameter apart 
and nearly the same distance from the laterals; laterals equal in size 
to the medians, larger than the anterior laterals with which they are 
contiguous. Anterior row of eyes in dorsal view strongly recurved, 
the median eyes being carried considerably forward as usual, larger 
than the laterals (diameters as 11:7), a little more than their radius 
apart (six elevenths of diameter), only half as far from the laterals; 
in front view the row is straight or nearly so. Area of median eyes 
subquadrate, being very slightly wider in front than behind. Cheli- 
cerae much longer than the height of the clypeus, (Plate 15, fig. 8). 
Labium wider than long in ratio 22:13; distally widely truncate. 
Sternum subtriangular; longer than wide in ratio 6:5.5; caudal 
process obtusely rounded, (Plate 15, fig. 7). 
Paired claw of leg I with seven or eight teeth of which the proximal 
ones are very short, (Plate 15, fig. 9). 
Abdomen subglobose, smoothly rounded, with no irregularities or 
tubercles.
