Colour. The anterior part of céphalothorax and the sclerites 

 brown, the posterior half of céphalothorax paler; palps dark red- 

 dish brown ; the legs and the interstitial parts palish brown. 



Céphalothorax about as long as it is wide, flattened, the po- 

 sterior half nearly parallel-sided, the anterior part broadly and 

 regularly rounded; the anterior transversal groove not very con-

 a longitudinal groove. F'emur with a short, but distinct stalk, ro-
