usual places; the part which bears hairs I, II aud III is 

 stronger chitinized, projects a little beyond the distal end 

 of the coxa (where the free palp is implanted) and 

 bears the long slender horn, which is more or less S-shaped 

 so that with its congener it similates a lyre. One observes 

 moreover inward of the horns the styli which are situated 

 so close to the horns, that I at first thought they were 

 bifid. Falpi long and slender, each joint beyond the 

 femur diminishing in width, and all the joints diminishing 

 in length. Dorsally (fig. 3) the trochanter is bare; the 

 femur provided with 3 bristles ; the genu with 4 ; the 

 tibia with 6, 2 of which quite distally ; the tarsus bare ; it 

 bears however at its top 4 transparent hairs, of which the 

 two inward smaller. Ventrally (fig. 8) the trochanter 

 with the usual 2 bristles ; the femur with the usual 2 hairs 

 of which the outer one in the middle of its length is a 

 bristle, the inner one quite distally is again a bristle (not 

 a knife) ; the genu with the usual 2 hairs inward and 

 distally, close together, of which the hinder one is a bristle 

 (not a knife) and the distal one a club-shaped flat hair (a 

 folding-stick, not a knife). The tibia with 4 hairs (not 2) 

 of which the 2 usual distal ones are bristles, the outer ones 

 strong hairs. Tarsus with the usual inner and proximal bifid 

 fork, moreover with only 2 bristles, and a distal very fine 

 hair. At its top it bears the 4 hairs already quoted of above. 

 Legs (figs. 2 and 1) short, resp. about 1225, 1155, 1050 

 and 1400 i^ long. Fore-legs rather thick; hind-legs rather 

 slender. The coxae of the legs ventrally (fig. 2) with the 

 usual 2, 2, 2, and 1 hairs respectively. The joints of the 

 legs are provided with bristles of the usual number and 

 situation, two dorsal and two lateral rows. Noticeable are 

 only: Femur I with a distal long bristle, which is directed 

 backward and curved inward over the palpi, and cross its 

 congener. Genu I proxiraally with a similar bristle but 

 curved outward. Femur II distally with two similar but 

 smaller bristles, of which one curved inward, and one 

 outward. Tarsus II (fig. 4) distally with two small thick
