 well developed; genu and tibia short; tarsus well known as the 

 appendiculum. Femur dorsali^ with 1 hair almost in the middle; 

 genu with 1 hair proximally; tibia with 1 hair close to the tarsus 

 and, quite distally, the «claw» with 2 basal inner tubercles; tarsus 

 with 2 combs. Coxae ventrali^ with 1 haii' close to the trochanter; 

 femur with 1 hair in its proximal half; genu bare; tibia with 

 2 hairs one inner and one outer; tarsus with 2 long crooked 

 claw-like hairs. 



Legs (fig. 34), The two fore-pairs slenderer than the two hind 

 pairs. Femur 4, 2, 3, 4 and genu 1 2, 3 wùth a feather-like 

 hair each. Tibia 1 with 1, and tibia 3 and 4 with 2 tactile 

 hairs each. All the tarsi distally with 2 tactile hairs each. Other 

 sejise (olfactoric?) hairs: genu 1 distally with a minute rodlike 

 hair; tibia 1 distally with a ditto; tarsus 1 in the middle with

 8haj)e known. — Texture smooth in the shields, finely wrinkled 

 in the unprotected parts. Dorsal side. There is but one (anterior) 

 shield, this is almost trapezoidal, wider than long, wider posteriorly, 

 with 3 hairs in each corner. On the unprotected part 4 transverse 

 rows of 4 hairs each, ^living together 28 hairs on the dorsum. 

 The hairs are feathers (fig. 36). 



Ventral side (fig. 39). On coxae 1, 3 and 4 two hairs each; 

 on coxae 2 one hair. Between coxae 1 one pair; in the space

 before the anus 2 pair of ßne smooth hairs. Aside of the anus one 

 pair of feathers. Lateral hair hairy. 



Maxillae. (Fig. 38 ai)d 39) The palps are distinctly S-jointed; 

 the trochanter being very short; the femur wel developed; the 

 genu very short, better discernable on the ventral side; the tibia 

 short but distinct; the tarsus is known as the (.(appendiculum».
