Tibia about 24 (x wide ; with 2 apical strong spurs and 2-3 smaller spines ; in fore legs the femur usually shorter and sometimes as long as the tibia, the ratio their lengths being 1 : i-i-i (1-06). Tarsus about 21 \l wide ; tarsal digitules apically knobbed, about 37(1 long. Claw gradually tapering to a pointed end ; ungual digitules fine. The following table shows the lengths of the leg segments (in microns) and the number of setae on each : Fore leg Middle leg Hind leg 43-49 (46) 43-49 (46) 46-52 (49) 8-12 (9-3) 8-13 (10-4) 9-12 (10-5) 58-67 (61) 58-67 (61) 61-70 (66) 4-6 (4-8) 4-7 (5-2) 5~7 (5'4) 162-174 (l68) 143-159 (153) 150-165 (159) 19-25 (21-3) 14-20 (17-2) 15-21 (17-8) 162-189 (177) 177-211 (189) 198-232 (214) 20-27 (23-5) 21-29 (247) 23-30 (27-1) 76-82 (79) 76-82 (79) 79-85 (82) 13-18 (154) 15-18 (16-9) 16-20 (18-1) 00-00 (24) 00-00 (24) 00-00 (24) 522-580 (555) 525-586 (555) 561-619 (592) Abdomen : 266-334 (296)[^ long and 289-327 (312)\l wide. Tergites of segments I and II small ; those of segments VIII and IX + X large and distinct. Sternites of segment VIII ill-defined. Ostioles entirely absent. Abdominal setae on each side : Dorsal setae 2-3 on segment I, 3-4 on segments II to VI, 2-3 on segment VII, and 1-2 on segment VIII. Pleural setae 2-3 on segment I, 3-4 on segments II to VII, and always 1 on segment VIII. Ventral setae 1 on segment II, 1-2 on segment III, 2-3 on segments IV to VII, and absent on segment VIII. Abdominal pores : Segment with 1-3 (2-6) pleural pores on each side ;
