The legs are long and rather slender ; their relative length appears

sparingly with hairs, and a very few prominent but short bristles, 

 several of which have a slender spine-like character. 



Ihe palpi are short, tolerably strong, and similar to the legs in 

 colour The cubital joint is straight and cylindrical in form ; it is

 spreads out prominently but obtusely both in front and on the outer 



and inner sides; from the extremity on the outer side there issues 

 a rather slender pale sinuous, corneous apophysis, and a very small 

 pointed tooth-like projection at the fore extremity. The digital joint 

 s of moderate size and of an oval form, obtusely rounded at id ex- 

 tremity; the palpal organs are well developed and complex, consist- 

 ing of several corneous spines and processes, but none of a very 

 remarkable character. •* 



The/alces and maxilla are similar in colour to the cephalothorax. 

 Ihe labium is short rounded at its apex, and transversely impressed 

 across the middle ; it is rather darker-coloured than the maxdlL

 blackish-brown colour, thinly clothed with hairs, and (visible in

 upperside and spots arranged in sinuous longitudinal lines on the

 by the greater strength of the eminence and the notch being much 

 shallower, as well as by differences presently to be noted of the 

 palpal structure; while in E. kochii the eminence, though less pro- 

 portionally strong, is higher and more distinctly notched than in
