29. Chelifbe plumosus, sp. n. (Plate XXX. figs. 20 a-e.) 



Female. 



Cephalotliorax. — Large rather indistinct ocular spots. The cephalothorax, which is 

 a little longer than wide, has two prominent, almost straight, transverse grooves. The 

 integument of the head and first thoracic tergite as well as of the small black spot on 

 the second tergite is strongly granular all over with rounded or pointed granules and 

 is provided with short distinctly clavate hairs. 



Abdomen (PL XXX. fig. 20 e). — The fairly long and slender abdomen has all the 

 tergites with the exception of the eleventh longitudinally divided by a broad band. 

 The sclerites, which on the first tergite are represented by a mere transverse line, are 

 distinctly granular. From 12-14 distinctly clavate hairs, short in front and fairly 

 long behind, are placed along the hindmost margin of each tergite, which possesses 

 besides a median hair, placed within the longitudinal band, slightly in front of the 

 row, and a lateral one distinctly so placed, at least in the median segments. The 

 eleventh tergite as well as the corresponding sternite bears a pair of " tactile " hairs. 

 The hairy spot in front of the vulva is rather small and insignificant (fig. 20 e). 



Anfennce. — The rather short galea extends a trifle beyond the terminal hair and has 

 six rather short distal branches, decreasing towards the end. 



Palps (PI. XXX. figs. 20 a-c). — The maxillce are smooth in the middle, laterally 

 granular ; the palps are very distinctly granular with the exception of the more or less 

 indistinctly granular lower surface and completely smooth fingers. The short hairs of 

 the three proximal joints are anteriorly more or less distinctly clavate, but posteriorly 

 obtuse or dentated, sometimes similar to those of the hand ; these, which are so 

 numerous that the hand appears somewhat shaggy, are slightly curved with the end 

 directed forwards, or, more correctly, the distal half makes an obtuse or even a right 

 angle with the proximal; the basal portion is without any teeth, while the distal 

 has about ten short teeth and consequently has a somewhat plumose appearance 

 (fig. 20 d). The trochanter, which is 1*6 as long as wide, is anteriorly moderately 

 convex and posteriorly fairly distinctly produced, but very slightly so dorsally. The 

 femur has a short and distinct stalk, beyond which it is of almost equal breadth 

 throughout, but for the slightly attenuated terminal part. It is 2"3 as long as wide ; 

 the anterior outline, beyond the stalk, is very slightly convex and then concave, while 

 the posterior is rather suddenly convex and then almost straight. The tihia, which 

 has a moderately long and well-marked stalk, is a little longer and broader than the 

 femur and 2-2 as long as wide ; anteriorly it is, beyond the stalk, moderately convex 

 and terminally a trifle concave, while the posterior outline, beyond the fairly big 

 condylus, is at first almost straight and then moderately convex. The chela, which is 

 2'4 as long as wide, is 1-4 as broad as the trochanter is long ; the hand, which is of 

 almost equal length to and 1"6 wider than the tibia, is 1"4 as long as wide, scarcely
