Male. 



Cephalothorax. — Ocular spots fairly distinct. The cephalothorax, which is some- 

 what longer than wide, has the anterior, almost straight, transverse striije broad and 

 fairly prominent, in contradistinction to the rather indistinct posterior one. The 

 integument is smooth, somewhat polished in front of the median stripe, and provided 

 with fairly long hairs. 



Abdomen. — The abdomen, which is fairly long and slender, has all the tergites, 

 except the first and the last, longitudinally divided ; the sclerites are almost smooth 

 and have along their hindmost margin in the median segments from 14-16 long and 

 moderately long hairs, in addition to two lateral and a single median one on each side 

 in front of the row. Number of " tactile " hairs on last segments is probably as in 

 Ch. similis Balz., but could not be investigated in the specimen examined. 



AntenncB. — The galea, which is fairly long and slender, extends distinctly beyond the 

 terminal hair and has from 6-10 branches differing in length. 



Falps (PI, XXXI. figs. 27 a-d). — Anterior surfaces of the joints minutely and not 

 very distinctly granular. The hairs are long or even very long. The trochanter, 

 which is about 1'5 as long as wide, is slightly convex anteriorly, and posteriorly is 

 produced into a short basal protuberance ; dorsally it is prolonged into a deep conical 

 and somewhat rounded protuberance, and its depth is less than that of the femur. 

 The femur has a short and well-defined stalk, beyond which it tapers towards the 

 extremity. It is about 1-9 as long as wide; the anterior outline is shghtly convex and 

 then concave, while the posterior beyond the stalk is very abruptly convex and then 

 almost straight ; dorsally it is somewhat more regularly, though more strongly, convex 

 beyond the stalk, and then slightly convex, most raised towards the middle, from which 

 it gradually slopes towards the end. The tibia, which has a rather short and well- 

 defined stalk, is a little longer and wider than the femur, and is 1-8 as long as wide; 

 anteriorly it is very strongly convex, almost semicircular in the middle and then 

 terminally very slightly concave ; posteriorly beyond the rather small condylus 

 and low ill-defined basal elevation it is almost straight and then strongly convex ; 

 the ventral margin is gradually and strongly convex in contradistinction to the 

 dorsal, which is somewhat produced in the middle (figs. 27 b-d). The chela, which 

 is about 2"6 as long as wide, is about 1'3 as broad as the trochanter is long; 

 the hand, which is distinctly longer and 1'3 wider than the tibia, is 1"6 as long as 

 wdde, only a trifle wider than deep, and 1*6 as long as the fingers, which do not
