 primary anterior angle seta and one secondary seta are longer than others.

 margin black, with a small, dark brown area; seta near suture thin, 

 blackish. Prosternite represented by a small, yellowish area of harder 

 integument. Horn relatively large, blunt, pale grayish. 



Legs (Figure 224) yellowish brown; coxae blackish dorsally and over a 

 varying part of basal area; articulation between femur and tibia black; 

 femora with indistinct dorsal dots. Tubercles of fore- and mid-coxae 

 situated dorsally and on posterior side of basal part; tubercles of hind 

 coxa smaller, sparser, situated on anterior subdorsal side; dorsal 

 tubercles of legs blunt or pointed, the other tubercles flat, scale -shaped, 

 serrated or with small spinules. Fore femur with convex dorsal and 

 almost straight ventral side; tibiae wide distally; tarsi narrower distally. 

 Mid -femur convex dorsally, slightly concave ventrally; tarsus almost as long 

 as tibia, narrower distally, as on forelegs. Hind femur shorter than 

 mid-femur, wider distally, slightly convex dorsally, with almost straight 

 ventral side; hind tibia and tarsus longer and narrower than on the 

 midlegs. Setae partly shown in Figure 224. Anterior primary setae of 

 fore coxa and trochanter (Figure 224, A) bifid apically; primary ventral 

 setae of fore femur situated basally, represented by a more apical, thin, 

 light, moderately long spine, and a massive, thick, yellowish more basal 

 spine; posterior primary seta moderately long, dark, situated between spines 

 and basal margin. Distoventral (anterior) seta of mid -femur situated in 

 middle of segment, forming a large, thin, grayish spine; basoventral seta 

 moderately long, thick, dark, situated closer to basal margin of femur 

 (Figure 224, B); primary posterior seta thinner, slightly longer, dark, 

 situated ventrally, some distance from distoventral seta. Primary ventral 

 setae of hind femur situated in middle of segment, forming a thin, pointed, 

 light spine, and short, dark, spine-shaped seta; primary posterior seta situated 

 ventrally near apex, long, dark brown (Figure 224, C). 



Lateral line on segments 2—7, light; moderately long hairs at posterior 

 . „r. niargin of each segment. 



Gills on segments 1—7; dorsal gills larger than ventral gills. 



Tergite of segment 9 (Figure 225) light chestnut brown, with 2—3 large, 

 light dots on each side anteriorly. Medioanal setae blackish brown, much 

 longer and thicker than anterior -angle setae; chaetotaxy as in Figure 225. 



Sclerite "b" of anal legs chestnut brown, with 3—4 large, pale, indistinct 

 dots (Figure 226); median distal seta black, long, much larger than medioanal 

 seta of tergite of segment 9; neighboring seta almost equally thick, black, 

 but about half as long; lateral seta dark brown, thinner, moderately long; 

 subapical seta of median margin slightly longer, reddish brown; a second 

 similar seta basally nearby; distoventral seta thick, dark brown; surface 

 with 9—10 thin, brown setae, some of them short, others moderately long. 



Sclerite "c" yellow, with broad, distinct, dark reddish brown lateral 

 margin; seta small, light. 



Claw brown basally (Figure 227), with a larger, lighter area on median 

 side; apical part dark reddish brown, with a transverse groove at curvature. 

 Seta 1 situated basally, short, thick, light; seta 2 situated dorsally near
