about the level of leg 3, tapering slowly backward; posterior 

 margin of abdomen rounded. Dorsal side for the greater part 

 protected by a scaly shield, which follows anteriorly to the 2d 

 pair of legs the margin of the body; further it is surrounded by 

 the improtected skin. The greatest breadth is at the level between 

 legs 2 and 3, tapering slowly backward; posterior margin round- 

 ed; before this last portion the lateral margin of the shields 

 bends a little inward. There are four longitudinal broken rows of 

 little hairs on the shield. Remarkable are a stronger hair on the 

 shoulder, a ditto on the level of leg 4, and two ditto quite pos- 

 teriorly. To the sides of the shield the skin has 9 hairs, and 

 behind the shield 9 pairs, of which 4 pairs quite marginal are strong. 



Ventral side (Fig. 12). There is a distinct furrow between the 

 scaly sterni-genital and the ventri-anal shields, and an indistinct 

 one between the ventral and anal portion of the latter. This ven- 

 tral portion therefore is hexagonal, with lateral angles. The sterni- 

 genital shield with 5 pairs, the ventral with 6 pairs of hairs. To 

 the sides of the ventri-anal shield about 9 pairs of hairs. — 

 Peritrema of middling size, reaching not beyond the coxae 2. 



Episfoma pointed anteriorly (Fig, 11). 



Mandibles chelate, without teeth, but with spoon-shaped appen- 

 dage. Fig. 13 shows us the left mandible seen from above; fig. 14 

 the right one from the ventral side. 



Hypostoma (Fig. 15) deeply split, with inner and outer appa- 

 rently movable malae, forming pincers, without teeth; the inner 

 malae blade-like, the outer like a spine. Palps. Fir.'t article with 

 a ventral appendage, imitating a swallow's nest (Fig. 16). 



Legs (Fig. 11) shorter than the body ; legs 2 and 3 not much longer 

 than its greatest breadth. On femur 1 and 2 the common spines; 

 coxa 2 (Fig. 12) with sharp spur forward. 



Female. Length about 540 ^i. — Colour pale, with darker 

 straw-coloured shield. — Shape elongate, tapering to both ends, 

 except when the animal is swollen , in which instance it is broadest 

 posteriorly, with median incision. Dorsal side (Fig. 17) for the 

 greater part protected by one shield, with scaly surface, tapering
