The carapace is wide, ovoid, slis^htly convex, covered 

 with short hairs and with granulations, and has four lobes 

 in front. The lobes arc flat and are separated by deep 

 grooves. The antero-lateral edges are very curved ; they 

 are divided into four lobes which do not exceed the 

 general curve of the carapace ; the two first lobes are 

 almost one. The postero-lateral borders are short and 

 concave. The front is very strongly notched in the 

 middle. The basal antennal joint is wide, but very short ; 

 it is united with a long and narrow subfrontal prolonga- 

 tion. The pterygostomian regions are finely granular. 



The fingers of the pincers are black, 'and this coloration 

 extends, in very old males, upon the external and internal 

 face of the hands as far as the articulation of the fifth joint ; 

 in the female the fingers only are black. The walking legs 

 are covered with hairs like that on the carapace. The 

 fourth joint is smooth on the outside, and granular above

 last joint is long, granular, and terminate in a sharp point. 



The abdomen of the male is long and narrow.
