or trochanter very short, scarcely visible. Third joint or femur 

 enormously developed , with a hairy hair, which reaches the tip 

 of the tibial claw. F'ourth joint or genu very short. Fifth joint or 

 tibia with a hair and the usual claw with one inner basal tubercle. 

 Sixth joint or tarsus as usual with the two nearly straight combs. 

 Ventral side (Fig. 48). The first joint or coxa, with one hair, 

 is fused with that of tlie other side to form the under side of the 

 head and a tube around the stylet-shaped mandibles. The second 

 joint or trochanter shoit but distinct. The third joint or femur 

 with two hairs. The fourth joint or genu shoi't but distinct. The 

 fifth joint or tibia with the formidable claw. The sixth joint or 

 tarsus with the usual two claw-like hairs. 



Legs. The coxae (fig. 48) i, 3 and 4 with two fine hairs each; 

 coxae 2, as far a I could discern, with one hair. All the femurs 

 (fig. 47) and trochanter 4 with a feather-like liair. The proximal 

 third part of tarsus 1 wider than the distal two thirds of it, and 

 provided with a small hair and a thorn-like sense hair. 



Female. Length 584 [>■. — Colour., shape and texture like in the 

 male. — Dorsal side (Fig. 50) protected by two dorsal shields. 

 The anterior shield trapezoidal, wider than long ; the posterior shield 

 trapezoidal, longer than wide. On the lateral margin of the anterior 

 shield 4 feather-like haiis; between the two shields, quite laterally 

 1 ditto ; on the lateral margin of the posterior shield 3 ditto ; behind 

 the posterior shield 2 ditto; so that on the dorsal side we observe 

 two somewhat wavy longitudinal rows of 10 feather-like hairs each. 

 N. B. The last pair sometimes may be placed on the ventral side! 



Ventral side (Fig. 51). The skin is finely wrinkled, except the 

 spaces occupied by the underside of the head, by the 8 coxae 

 (generally called epimera), and by the genital and anal covers. In 

 the space between the 8 coxae 2 pair of little hairs. Behind coxae 

 4 one pair of ditto. Before the genital covers 2 pair of smaller 

 hairs; the genital covers with 2 small hairs each; the anal aperture 

 flanked by three small feather-like hairs. Laterally of coxae 2 a 

 large feather-like hair. 



Mandibles as usual, stylet-shaped; internal.
