18 ARKIV FÖR ZOOLOGI. BAND 3. N:0 28. 



Tibia nearly as long as the f emur, with narrow base, wide- 

 ning gradually distally, exteriorly with three, ventrally with 

 two, dorsally with one, and interiorly with three hairs. 



Tarsus with short basitarsus, shghtly shorter and thicker 

 than the tibia, gradually widening distally and in the distal 

 third narrowing towards the rounded top; richly provided 

 with fine, rather long and straight hairs of which one median 

 exteriör, one interiör and 3 — 4 end hairs are longer than the 

 others. 



Legs II — IV very thick, of nearly the same length, the 

 last pair being slightly longer. 



Cox8e short, ringshaped, ventrally provided with one 

 powerful, very sharply curved pointed spine each, of which 

 that of the last pair is only half as big as the others. 



Trochanter II and III ventrally with two small hairs, 

 trochanter IV with two sharply pointed spines. 



Femora with distinctly demarcated basifemora. 



Telofemur, genu and tibia of nearly the same length. 

 Telofemora II — IV dorsally provided with two median brisb- 

 les and near the distal end with two stout straight perpen- 

 dicular bristles. Genua II — IV dorsally with about 6 smaller 

 bristles of which one on genu III and three on genu IV are 

 larger than the others. 



Tibia IV also with greater bristles than those of tibiae II 

 and III. 



Tarsi with demarcated basitarsi; telotarsi II — IV dis- 

 tally and dorsally with one long tactile hair. 



Tarsi II — IV ventrally, at the end, provided with a strong 

 toothshaped tubercle (Fig. 28, Pl. I). 



The feet II — IV without claws, provided with very large 

 ambulacres (Fig. 28, Pl. I). 



Fe7nale (Fig. 25 Pl. I.) 



The general shape and the dorsal side is exactly like that 

 of the male except for the greater size. 



Ventral side. 



Tritosternum shaped like that of the male. 



The jugular shield (Fig. 21, Pl. I) single, shaped like that of 

 the male, but the posterior margin is not so convex and the 

 two bristles are inserted nearer the sides ; near the posterior edges 

 is a pair of rather large fissures.
