Distodorsal notch of the coxa of the forelegs (Figure 350) reaching the 

 distal third of the segment; it reaches farther in the midlegs and hind legs. 

 Basodorsal seta of coxa of forelegs thin, small; anterior distodorsal seta 

 slightly longer, situated near the margin of the notch; posterodorsal seta 

 situated in the middle of the segment, much larger than the anterior setae; 

 both anterior surface setae thin and small; both distoventral setae light, 

 spinelike, short; posterior seta slightly longer than the anterior seta. 

 Basodorsal seta of coxae of midlegs and hind legs (Figure 351 ) strong and 

 dark, long; anterior and posterior distodorsal seta even longer near the 

 apex of the notch; the 2 anterior-surface setae are small and thin (as on 

 the forelegs); anterior distoventral seta, light brown and small; posterior 

 seta much longer, longer on the hind legs than on the midlegs. Anterior 

 and posterior seta of trochanter of forelegs small and thin; the posterior
