wide, slightly more than as long as the maxillae, a little con- 
. tracted and rounded at the tip. 
The sternum is 1 times as long as wide, truncated in front, 
and rounded behind. It projects between the anterior coxae, 
which are separated by the width of the labium. 
The relative length of the legs is 1, 4, 3, 2; their relative 
stoutness 1, 2, 3, 4, the fourth being plainly more slender than 
the third. There are femoral, patellary, tibial and metatarsal 
spines on the four pairs, those on the tibiae and metataisi of the 
third and fourth being found both above and below, and those 
on the metatarsi extending to the base. 
9 . Total length 13.6 mm. Width of abdomen 4.7 mm. 
Cephalothorax: length 4.8; width 4.2; height 2.8. 
Legs 10.6, 9.1,10.4, 11.7. Pat. + tib. I 4.8; pat. +tib.III

The cephalic plate is not so much raised as in $ . The tho¬ 
racic part falls gradually for )/\ of its length, not steeply from 
the dorsal eyes. The first row of eyes is but little curved, less 
than in S . The anterior eyes are all relatively larger than in 
the $, the middle eyes being more than twice as large as the 
lateral. The maxillae are more widely rounded, and the labium 
shorter and more slender than in the <? ■ The relative length of 
the legs is 4,1, 3, 2, and the relative stoutness 1, 2, 3, 4. There 
are no patellary spines on the first and second pairs. 
Coloration. ( S ). The cephalothorax varies from reddish 
brown to black, and has a central spot and several lines white, 
the abdomen varies from light testaceous to dark brown, and 
has two longitudinal white bands, on each of which is a row of 
black dots. The legs and falces are dark brown; the clypeus is 
dark brown above, with a pale band just over the falces; on the 
upper portion two lines of white hairs beginning between the 
middle eyes, run obliquely outward to the insertion of the 
palpi; the palpus is brown, with a white line above, meeting 
that on the clypeus. The sternum, coxae and mouthparts vary 
from light testaceous to dark brown; the venter is brown with a 
longitudinal white line on each side. ( 9 )• The cephalothorax
