Cephalotliorax. — Head without any vestige of eyes; ce- 

 phalic sternum (fig. Ib) nearly as broad as long. Second tho- 

 racic tergite has a faint whitish stripe beneath its mesial Hne. 



Palps. ^ In both sexes (figs. le and Id) half as Jong 

 as first pair of legs, robust, with the femur, especially in the 

 male, conspicuously deeper than in any other species of the 

 tribe; the articulation between trochanter and femur is also, 

 and especiaJly in the male, longer than in any other form. 

 The lower margin of femur is unusually, even exceedingly, 

 short; this margin has a very small, robust, obtuse process, 

 the end of which is considerably longer from the proximal 

 than from the distal end of the upper margin of the joint. 

 The claw is moderately long, a little more than half as long 

 as the upper margin of tarsus. — Male (fig. le): Trochanter 

 with the lower anterior angle produced into a good-sized, 

 somewhat curved, pointed process; femur with the upper 

 margin exceedingly convex; patella about two and a half 

 times longer than deep, with a good-sized curved pointed pro- 

 cess or tooth on the lower side a little before its middle; tibia 

 with three small teeth on the lower side. — Female (fig. Id): 

 Trochanter with the lower anterior angle produced into a short
