Metathorax. Metanotum with anterior margin strong medially ; suspensorial sclerites 

 absent ; a small, additional sclerite occasionally present anterior to postnotum. Postnotum 

 consisting of two narrow, transverse sclerites in a tandem alignment on each side. Metatergal 

 setae : 0-2 (average 0-7) f.s. and 0-2 (average o-8) h.s. on each side. Pleural ridge considerably 

 reduced, extending only a short distance above coxal articulation. Vestigial precoxal ridge 

 present. Episternum reduced to a subtriangular plate ; epimeron produced posteriorlv

 f.s. and 0-2 (average 0-3) h.s. Postmetaspiracular setae : 6-1 1 (average 8-2) f.s. and 0-5 

 (average 1 -7) h.s. Metasternum represented by a transverse plate. .-1 nterior metasternal setae : 

 13-24 (average 19) f.s. and 0-3 h.s. Posterior metasternal setae : 5-16 (average 8-4) f.s.

Coxae : inner surface of front coxa with small projections ; with 3-7 (average 5) f.s. on the 

 fore and 14-21 on the middle and hind coxa, and each with 6—12 h.s. ; fore coxa without 

 coxal bristles ; apical seta about J as long as trochanter. Trochanters 23-29 u. wide ; with b 

 oval sensilla, 7-15 f.s. and 6-9 h.s., the latter including -' minute setae near basal ridge, one small 

 seta on outer margin and a long apical seta which, on the fore trochanter, is 2024 (average 

 2-3) times as long as width of trochanter. Femora of medium width (36-44 u.), the ratio width 

 to length of hind femur being 1 : 4-8-5-4 (average 52) ; each with 18-33 f.s. and 13-25 h.s.

 with 64-99 setae of which 20-35 are h.s. and 39-68 f.s., the latter about as long as width of 

 tibia ; apical spur on fore tibia short, about half as long as on the other tibiae. Tarsi 19-27 u. 

 wide, hind tarsus 6-4-7-8 (average 72) times longer than wide ; each with 12-28 f.s. and as many 

 h.s. ; tarsal digitules subequal, about as long as claw. Claws of medium length, about as long 

 as width of tarsus ; slightly curved, with small denticle near tip ; ungual digitules subequal, 

 about as long as claw.

Segments I-VII : tergites on segments II and III represented by 3 small sclerites on anterior 

 margin — one medially and one on each side, and on segment IV by a small median sclerite. 

 Pleurally a continuous band of sclerotization extends from segments [V— VII, with a separate 

 small sclerite situated ventral to this band on each of segments IV— VII, Sternites on segments 

 II-VII represented by a transverse plate, which is weak or interrupted medially. Caudal 

 extension of segment VII small, rounded. Dorsal setae : sometimes one or two f.s. on segment 

 I ; usually one h.s. on each side on I and each of segments V-VII, occasionally also a single 

 h.s. on segments II— IV. Pleural setae consisting of dorsopleural setae : 0-3 (average 0-5), 

 0-2 (average o-6) and 0-2 (average o-8) f.s. on segments III and VI and 0-1 (average 0-7) 1, 1, 

 1-2 (average 1-2), 0-2 (average 1-3) and 1-3 (average i-8) h.s. on segments I— VI respectively, 

 and of ventropleural setae : 0-1 (average 0-4), 0-3 (average 1-5) and 0-5 (average 2-1) f.s. on 

 segments IV-VI and 0-1 (average 04), 0-1 (average 0-5), 1-2 (average 12), 0-1 (average 0-9)
