primary distal setae including a posterior subventral seta in form of a large, 

 thick, strong spine and a similar but smaller anterior ventral seta; a row 

 of small, light spines in addition to priinary setae ventrally. Tarsus with 5 

 thin, moderately long setae, including 2 apical setae dorsaily; anterior 

 subventral seta forming a thick, strong spine as on tibia, but smaller: 

 posterior surface with dark, short, strong subapical seta. Claw large, slightly 

 curved, with a short, strong spine at base. 



Midlegs (Figure 817, B) resembling hind legs more closely than in 

 Oe.ochracea. Coxa slightly oblong,with large, brownish, basal dots laterally. 

 Basodorsal seta and posterior apical dorsal seta long; anterior apical 

 dorsal seta shorter; several, long and small, secondary setae dorsaily; 

 513 anterior surface with a group of 3 — 4 setae, including 2 moderately long, 

 primary setae; ventral and subventral setae numerous; both distoventral 

 setae large, situated among secondary setae. 



Anterior seta of trochanter strong, moderately long; posterior seta thin: 

 2 posterior basal setae dorsaily, a row of secondary setae anteriorly; 

 basoventral seta and both posterior ventral setae long, strong; 2 anterior 

 ventral setae smaller, situated among short and long, secondarj^ setae, some 

 of them in form of small, light spines: sparse, white, hairlike chaetoids in 

 addition to setae.

Femur with a long basodorsal and a long apical dorsal primary seta, the 

 latter among almost equally large, secondary setae; sparse setae further 

 basally at dorsal margin; sparse, long setae subdorsally; ventral side with 

 setae of different length, small, light spinules and light chaetoids. 



Tibia with a long, strong, primary subapical seta posteriorly; a similar 

 large, dark seta situated in anterior subdorsal area in the middle of the 

 tibia; thin, sparse setae dorsaily and subdorsally, among them several 

 moderately long, thin setae; a row of 12 — 13 strong, light spines, including 2 

 large spines ventrally.
