above the spinners, the space immediately above the latter organs 

 being black. The lateral area exhibits a more or less well- 

 defined, longitudinal, sinuous white line, often entirely obsolete 

 in the middle. The ventral surface is uniformly black or lighter 

 brown. 



Sternum dark brown-black, very convex, covered with 

 scattered granulations, each of these bearing an erect black 

 hair. 



Caput prominent in front ; clypeus scarcely as wide as the 

 ocular area, very concave, bearing in front immediately below 

 the eyes a single, strong, upcurved bristle (fig. II. 4). 



Eyes situated upon dark spots ; those of posterior row equal 

 in size and equidistant. 



Central anteriors smaller than the laterals and separated by 

 almost a full diameter from each other (fig. II. 3). 



Falces three times as long as the clypeus, slightly attenu- 

 ated and slightly divergent at the apex in the male sex, 

 parallel in the female sex. 



The outer surface of the basal joint is in both sexes trans- 

 versely furrowed with a row of stria?. The upper margin of 

 the fang-groove is furnished with three sharp teeth, the two 

 at the angle being longest. 



Legs long, not stout, the femora of the first pair bearing 

 one long spine on the upperside, the others bearing none. 

 Genual joints bearing each one spine. Tibia? of all four 

 pairs bearing two erect spines on the upperside, those of the 

 first two pairs bearing in addition two lateral spines on either 

 side near the apex. 



Palpus of Male. — Humeral joint bearing on inner side at 

 the base a small spine-bearing tubercle. Cubital joint rather 

 longer than broad, convex above, bearing a short sinuous 

 bristle near the apex above. Radial joint longer than the 

 cubital, wide in front, bearing a long curved bristle near apex 

 above. 



Digital joint with the palpal organs forming a small, com- 

 pact, rounded mass, having on the outer side near the base a 

 falciform process, small, rather abruptly carved upwards, bifid 

 at its termination, one branch being produced into a slender, 

 sinuous, blunt process, riot aculeate. 



The lateral stylum curves upioards and forwards, terminating 

 in two black points, the lower one being longest, but its apex 

 scarcely reaches the anterior margin of the palpal organs. 

 This process is much smaller and less prominent than in 

 " zebrinus/' as indeed is the whole digital joint (fig. II. 1, 



A, B) . 



The epigyne of the female is less prominent when viewed in
