inner side beyond the stalk is first moderately convex, and 

 thereafter concave, while the outer side is regularly convex 

 from the base to the tip. The tibia is as long as and dis- 

 tinctly broader than the femur, with a rather long and well- 

 marked stalk ; the inner side has first a deep notch to mark 

 oft' the stalk, but is thereafter distinctly convex to near the 

 tip, where a gentle concavity is found. The outer side, 

 beyond the low basal protuberance which forms part of the 

 articulation and the following low concavity of the stalk, is 

 convex to near the tip, where a short low concavity is found. 

 The hand (t'gs. 2 d-e) , wliich is a little shorter than the 

 tibia, bnt 14 times broader, is higher than broad, almost as 

 high as long, and as high as the fingers are long. The 

 curvature of the upper and inner surfaces, which are almost 

 semicircular, is more marked than that of the lower and 

 outer. The fingers, which gape slightly when closed, are 

 provided with the usual row of triangular teeth ; the immov- 

 able finger hears also on the inner side four accessory teeth 

 behind the distinctly hooked tip, and at some distance from 

 these four others near the middle ; on the outer side there 

 are "about nine of these teeth distally. The movable finger 

 also bears a few on the inner and outer side near the tip. 



Cox(E (fig. 2 a). — The first pair of coxae are almost 

 trapezoid; the two following pairs are nearly triangular, as 

 the inner margin is very short ; the fourth pair have a similar 

 shape, but the inner side is broader and the intero-posterior 

 angle is obtuse and rounded. 



Leffs (figs. 2f-g). — The legs are moderately long and 

 slender; the hairs, especially the dorsal, are more or less 

 enlarged distally, with a number of minute spines in all 

 directions ; this kind of hair is called clavate. The hairs on 

 the ventral surface of the tarsi are almost simple ; on each 

 side of the claw there is a strongly curved hair corresponding 

 to the bifurcated one found in (Jh. cancroides, L. (c/. p. 120). 

 The tarsus of the fourth pair of legs has some longer pointed 

 hairs near the claws, but does not bear an inner "tactile" 

 hair, in contrast to most other species with the exception of 

 Ch. cimicoides, F. The trochantin of the first pair with a 

 well-marked stalk. The tibia, which is distinctly longer than 

 the tarsus, is, like the latter, enlarged distally ; this difl'erence 

 in length between the two segments is, as usual, yet more 

 market! on the fourth pair of legs. 



Colour. — The maxillae, palps, and cephalothorax are bright 

 reddish brown (the two black transverse grooves excepted) ; 

 the coxai and legs are lighter; the sclcrites of the abdomen
