 Female. — Cephalothorax dark reddish brown, blackish about the 

 eyes; a lighter uneven-edged marginal band on each side, and a similarly 

 colored narrow median stripe more or less distinct; sides of cephalo- 

 thorax densely clothed with black pubescence with more scattered 

 hairs of yellowish intermixed ; the narrow median stripe clothed with 

 yellowish or golden-brown hair, which forms a bright stripe which 

 continues forward as a line between the eyes and reaches the anterior 

 row, the stripe expanding posteriorly about the dorsal groove and then 

 again narrowing down the posterior declivity to the posterior margin ; 

 the middle stripe of pubescence sometimes obscure in middle region, but 

 always bright at anterior and posterior portions; along each side similar 

 yellowish hair forms a narrow marginal stripe which is narrower than 

 the broader supramarginal stripe of tegument ; front margin of clypeus 

 at middle with a fringe of yellowish hair. Chelicene, including claws, 

 black, clothed with moderately long black pubescence without any 

 short paler hairs. Endites and labium brown-black, lighter at tips. 

 Sternum black, a narrow light colored median line anteriorly; clothed 

 with black hair. Coxm of legs beneath black, lighter, yellowish brown, 

 laterally, at base beneath a similarly colored light spot which is mostly 

 acutely pointed distally. Legs brown, of light shade in young specimens, 

 becoming dark reddish brown with age, deeper colored distally; all joints 

 excepting the tarsi and the metatarsi with light cross-bands which are 

 distinct above, especially on femora, but which may be obscure beneath ; 

 light rings much more distinct in young specimens than in old, and in 

 the latter on the posterior pairs of legs than on the anterior; legs 

 densely clothed with long black hairs intermixed with shorter yellowish 

 pubescence, the latter mostly confined to the lighter bands in tegument.
