lesced without visible suture. The corniculae hypostomatis or ex- 

 terior rualae are norrual. The interior, however, long, filiform. The 

 legs are sleuder, those of the first pair as long as the body; the 

 others shorter, scarcely longer than the breadth of the body. 



Male. Length about 450 /*. Shape (Fig. 17); well shouldered, 

 broadest at the shoulders, tapering rapidly toward the apex, with 

 a secoud indication of a shoulder near the first pair of legs, 

 and tapering very slowly toward the posterior end of the ab- 

 doinen. Behind the shoulders the side is somewhat concave. The 

 colour is that usually shown by Pachylaelaps. The dorsal shield 

 shows exactly the same distribution of hairs as that in the nymph. 

 The shields of the ventral side (Fig. 18) have all coalesced. The 

 sternal part projects forward and ventrally with an undulated 

 edge, so that the mentuui is situated between this prolongation 

 and the jugular region. The epistoma (Fig. 19) differs frorn that 

 of the nyinpb, as the comb is placed immediately on the base, 

 which bas a denticulated edge and therefore strongly reminds 

 us of that of the genus Macrocheles. The hypostoma (Fig. 20) 

 differs greatly from that of the nyrapha. The bases of the maxillae 

 are coalesced so that they leave a nearly circular opening through 

 which the base of the ligula is visible. The malae interiores are 

 blade-like, very transparent. The rualae exteriores long, well chi- 

 tinized. The movable finger of the chelae (Fig. 21 — 23) bears an 

 almost S-shaped broad and flat copulation-organ, provided with 

 about three blunt teeth on its distal end and one blunt tooth on 

 its inner side. The genu and tibia of leg 1 (Fig. 24) are distally 

 provided with two little teeth. The femur of leg 2 (Fig. 25) has 

 a strong thorn directed forward ; the tibia a thumb-like apophysis 

 directed backward; and the tarsus bears a little thorn distally, on 

 the outer side, next to the praetarsus. 



Female. Length about 450 (a. Colour like that of the nympha 

 and the male. Shape (Fig. 26) between those of the nympha and 

 the male. Dorsal side. Distribution and number of the hairs ex- 

 actly like those in the nympha and the male. On the ventral 

 side (Fig. 27) we observe the coalesced sternal, lateral and mèta-
