pair of excavations ncar thc postero-lateral angles. M e t a s t e r n a 1 s li i e 1 d s sniall, 

 triangulär, situated in tlie coraors between coxse III and IV and provided witli one 

 pair of long bristles. Genital and ventral shields fused together to one shield, 

 wliich extends backward beyond the middle of tlie belly and widens considerably, 

 behind coxa> IV, towards the posterior V4 of its length; from thence it falls off 

 towards the posterior niargin which is deeply concave in the middle; 4 pairs of mar- 

 ginal bristles. Anal shield large, triangulär, with rounded angles and sides, separated 

 from the geniti-vcntral shield by a streak of soft skin, as broad as the length of the 

 anal aperture; with the usual three hairs, two of which are placed just behind the anal 

 aperture while the third, terminal one is a straight bristle. Anal aperture oval, in the 

 centre of the shield. Inguinal shields small, rounded and finely punctured, placed 

 outside and behind cox» IV. Stigmata in the usual place. Peritrematic shields 

 present, allthough very narrow; they form a small plate behind the Stigmata, and 

 are at first very narrow, but widen on the external side of coxse II, and extend 

 forward as far as to the anterior Shoulders, above legs I. 



The epistoma is shaped like that of the male, but a little longer. 



The mandibles (PI. 2, fig. 31); the chela rather narrow and slender; the lower 

 jaw nearly twice as broad as the upper one and slightly longer, with long, strongly 

 curved terminal tooth, the inner (posterior) side of which is excavated ; besides there 

 are two small, sharp and somewhat backwardly directed teeth in the distal third, one 

 close behind the other; the upper jaw with short terminal tooth, the posterior edge 

 of which is provided with a small tooth; the sense hair is comparatively large and 

 placed on a level whit the third small tooth ; f urther backward, behind the middle, 

 there is a blunt tooth, at the back of which the edge is raised. 



The hypostoma (PI. 2, fig. 22) resembles mucli that of the male, but the 

 maxillary plates are divided into 2 pairs of transparent slips, the external ones of 

 which are rounded, with no fringes; the median ones shorter, pointed and finely 

 fringed. The maxillary palps shaped like those of the male. 



Legs shaped like those of the male, but larger in proportion, with stouter 

 bristles. Coxa I, anterior bristle short, very stout, the posterior one twice as long, 

 directed backward ; femur I like that of the male ; genu the samc, but with one 

 longer, poniard-shaped bristle on the dorsal side, proximally; all the bristles on the 

 dorsal side of genu and tibia perpendicnlar,
