metatarsus and tarsus pale yellow-brown ; the two posterior pairs 

 of legs are somewhat paler, but with similar brown rings and 

 squamules intermixed with upstanding brown bristles. The palpi 

 are yellow-brown, with thick brushes of long white bristles. 



The ground-colour of the abdomen is pale yellow, covered with 

 thick masses of white, black, and red lancet-shaped scales all 

 mixed up together. 



The eye-space and thoracic part each occupies about one-half of 

 the total length of the cephalothorax, but, the upper flat part 

 continuing for about halfway on the thoracic, the rear slope is 

 quite steep at the end. 



The front row of eyes is straight along the upper edges, the 

 rear eyes about the same diameter as the front lateral. The 

 second row of eyes halfway between these two are quite small ; 

 the clypeus about one-foui-th the diameter of the front median 

 eyes.

 a., lip and maxillae; b., mandibular teeth and fang; c, epigyne. 



The mandibles are convex on the outer side. The fissidental 

 tooth is rather high and its own length distant from the base of 

 the fang, its lower corner forms the larger of two conical teeth ; 

 on the outer margin are four teeth, tlie two upper being largest 

 and the lower quite small. 



The lip is clearly longer than broad, narrowed and rounded in 

 front, and more than half the length of the maxillae. The front 

 coxae are barely separated by the distance of the breadth of the 

 base of the lip, so that the sternum is narrower in front than at 

 the posterior end ; it is ovate, convex over the posterior two- 

 thirds, with a broad flat margin between it and the coxae. The 

 abdomen is oval, but is partially destroyed. The epigyne consists 

 of a pair of deep oval depressions iipright, side by side, separated 

 by a black chitinous ridge widest in the middle, which runs
