slightly exceeding the length of the outer surface of the femur of 

 the 4th leg. 



Legs 4, 1, 2, 3 ; 4th exceeding the 1st by rather more than the 

 length of its tarsus ; patella and tibia of 4t]i a little longer than of 

 1st (24 : 22) ; 4th leg strong, but the patella and tibia narrower than 

 the femur ; width and height of patella about equal, but barely 

 equal to half the length measured along the upperside ; tibia 

 lightly convex above, its width a little greater than one third of 

 its length and a little less than its height ; protarsus longer than 

 tibia (15'5 : 13"5) ; femur of 4th leg very robust, its height exceed- 

 ing one third of its length. 



Measurements in millimetres. — Total length 53 ; length of cara- 

 pace 24, width 20 ; length of 1st leg 5-5, of 2nd 49, of 3rd 4, of 

 4th 65 ; length of femur of 4th leg 18-5, height 7 ; length of the 

 tibia 13-5, height 5. 



Loc. Benito Eiver {G. L. Bates). 



The subjoined table will show how this species may be distin- 

 guished from the rest of the species of Hysterocrates known 

 to me : — 



a. Width of tibia of posterior leg equal to that of femur ; 



tarsus of palp moi'e tumid above at base crassipes Foe. 



b. Width of tibia of posterior leg much less than width of 



femur ; tarsus not tumid above at base. 

 a^. Carapace long ; area between ocular tubercle and pos- 

 terior median emargination exceeding the width ... ffiffas Poc. 

 b^. Carapace wider, its width equal to the area between the 

 tubercle and the posterior emargination. 

 a^. Femur of 4th leg slender, its height barely one third 

 of its length. 

 a^. Hairy clothing of legs reddish brown ; 4th leg 



thickened, the tibia almost as tliick as the femur, laticeps Poc, 

 b^. Hairy clothing deep olive-brown ; 4tli leg unmodi- 

 fied, the tibia much thinner than the femur kercules, sp. n. 



6'. Femur of 4th leg stout, its height considerably 



exceeding one third of its length robustits, sp. n.

Two immature specimens probably referable to this species, which 

 was recorded from the Eio Quiliou (Congo).
