longer than deep. Claw half as long as the apper margin 

 of tarsus. 



First Legs. — Male (fig. 2 b): Slender, not fully twice 

 as long as the body. Coxa terminates very little in front of 

 the outer angle of the mandibJe. Femur scarcely longer than 

 tibia. Foot two thirds as long as tibia, fourteen and a half 

 times longer than deep, deepest at the end of metatarsus 

 (fig. 2 d) ; second metatarsal joint almost as long as the sum 

 of the five proximal tarsal joints; terminal joint very little 

 longer than the sum of the two proximal tarsal joints, and 

 2/5 as long as metatarsus. — Female (fig. 2 e) : Slender, not 

 fully '^J2 times as long as the body. Coxa terminates just at 

 the outer angle of the mandible. Femur slightly longer than 

 tibia. Foot slightly more than two thirds as long as tibia, 

 eleven and a half times longer than deep, deepest at the end 

 of metatarsus (fig. 2 g); second metatarsal joint a little shorter 

 than the sum of the five proximal tarsal joints; terminal joint 

 a little longer than the sum of the two proximal tarsal joints, 

 and -/5 as long as the whole metatarsus. 



Fourth Legs. — In the male nearly ^/a, in the female V4 

 as long as the body. Femur in the male (fig. 2 h) a little 

 less than three times (almost ^'/i times), in the female (fig. 2 i) 

 only somewhat more than two times (slightly more than ^ji 

 times) longer than deep. 



Three posterior abdominal Segments. — Withdrawn in 

 both sexes; in the male (fig. 2 k) the terminal segment is a 

 httle deeper, with the upper part above the insertion of fla- 

 gellum conspicuously higher, than in the other sex (fig. 2 m). 



Flagellum. — Male (figs. 2 k and 2 1): Short, very broad 

 and rather deep. The stalk is of middle length and very 

 compressed. The main piece is as broad as long, seen from 

 above subcircular, yet with the posterior margin feebly convex 

 and very long; on the posterior portion a rather deep excava- 

 tion is seen. Seen from the side the proximal half of the 

 lower margin of the main piece is a little convex, while the 

 distal part of the upper margin slopes strongly downwards 

 and backwards; on this large sloping surface is found the 

 above-named excavation which looks much backwards. The 

 setai on the upper surface are rather short, the lateral setse 

 of moderate length, but some setse on the lower surface are 

 exceedingly long, nearly as long as the main piece itself. —
