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 4th a little longer than of 

 1st (24 : 22) ; 4th leg strong, bat 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 i-obust, 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 55, 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. 



Log. Benito River {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 more tumid above at base crassipes Poc. 



h. 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 tbe 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 tliiek as the femur, laticeps Poc, 

 h^. Hairy clothing deep olive-brown ; 4th leg unmodi- 

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



b^. Femur of 4th leg stout, its height considerably 



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