Coxae : 14-24 (average 21 f.s. on the fore and 25-36 on the middle and hind coxa, and 1 

 with 6-1 1 h.s. ; fore coxa with 2-4 (average 2-7) capitate coxal bristles ; apical seta about £ as 

 long as trochanter. Trochanters 26-31 u. wide ; with 6 oval sensilla, 11-22 f.s. and 6-8 h.s, 

 the latter including 2 minute setae near basal ridge, one small seta on outer margin and a long 

 apical seta which, on the fore trochanter, is 1-5-2-4 (average 21) times as long as width of 

 trochanter. Femora of medium width (39-49 u.), ratio width to length of hind femur being 



1 : 4-5-4-8 (average 4-6) ; with 28-48 f.s. and 7-14 h.s. Tibiae 21-27 I* wide, ratio width to 

 length of hind tibia being 1 : 16-5-17-7 (average 170) ; each with 70-115 setae of which 

 16-31 are h.s. and 54-89 f.s., the latter about ij to 2 times longer than width of tibia ; a] 

 spur about the same size on all tibiae. Tarsi 21-23 H- wide, hind tarsus 6-7 (average 6-5) times 

 longer than wide ; each with 23-28 f.s. and 10-18 h.s. ; tarsal digilitles subequal, slightly longer

Segments I —V 1 1 : lergiles represented by 3 small sclerites, one medially and one on each side, 

 on anterior margin of segments II-III, and a weak transverse plate on VII ; sterniles usually 

 present on all segments, represented by a weak transverse plate on segments II, III and VII, 

 and a weak sclerite on each side on IV— VI. Caudal extension of segment VII extending 

 beyond the level of posterior margin of segment VIII, tapering, weakly sclerotized latero- 

 ventrally. Dorsal setae : 0-2 (average 0-7), 0-1 (average o-6), 0-1 (average 03), 0-3 (average 

 0-9), 0-1 (average 03) and 0-2 (average 0-3) f.s. on segments I— VI respectively ; one h.s. on 

 each side on I and each of segments IV— VII, and very rarely a single seta on II and III. Pleural 

 setae consisting of dorsopleural setae : 10-16 (average 13), 2-6 (average 4-1), 2-8 (average 4-2),
