 ratio width to length of hind femur 1 : 4-3-51 (47)- Tibia about 23^ wide, with 2 apical 

 strong spurs and 3-5 smaller spines ; the ratio lengths of femur to tibia in front leg 1 : i-i-i 

 (104). Tarsus about 2i[i wide and tarsal digitules about 400. long. Claw gradually tapering 

 towards a pointed end ; with a pair of finely pointed ungual digitules. The lengths of the leg
