 length 1 : 1-5-1-7 (i-6). Coxa and trochanter about 51 and 27(1 wide respectively. Femur 

 about 37 u. wide ; that of the fore leg shortest and that of the hind leg longest ; the ratio width 

 to length of hind femur 1 : 6-8-7-6 (70). Tibia about 2 1 (j. wide ; with two apical spurs and 

 5-8 smaller spines ; in front leg, femur shorter than tibia, the ratio their lengths being 1 : 11- 

 1-3 (12). Tarsus about 2ifjt wide ; tarsal digitules apically knobbed, 34-43 (37)(x long. Claw 

 gradually tapering to a pointed tip ; ungual digitules fine. The lengths of the leg segments
