in the British Musciim. 107 



has a smaller abdomen, with more distinct colours and slightly 

 longer palps. 



Variety. 



Cephalothorax. — The transverse grooves are very indis- 

 tinct, but the granulation much better marked. 



Abdomen. — The first three very short tergites have the 

 hindmost margin distinctly convex and the foremost concave; 

 the median tergites have both margins more or less straight, 

 while the last ones have the anterior margin convex and the 

 posterior concave. The sclerites are well developed and 

 divided by a broad longitudinal line where the skin is dis- 

 tinctly reticulated. The hairs are evidently clavate ; the 

 eleventh tergite possesses a number of very small round 

 spots similar to those found in Ch. eqvester, sp. n. [cf. p. 124). 

 The genital area seems to be different from that found in the 

 typical specimen. 



Antenna (PI. YII. fig. 1 e). — The flagellvm is composed of 

 four hairs, of which the anterior longer one bears many mar- 

 ginal teeth, while the second has only a few. The Imn'ma 

 interior has at least three distal lobes with very long teeth ; 

 the terminal spine is shorter, distinctly hooked, and provided 

 with six long teeth. Tlie galea (fig. 1 e) has some few teeth 

 distally and is a little longer than the hair at its base. The 

 teeth of the serrula (fig. 1 e) are high, the terminal is pointed, 

 and the basal is only slightly enlarged distally. 



Maxilla. — The maxillae are not only be?et with granules 

 laterally, but bear also some larger protuberances. 



Palps. — The granulation, especially that of the hand, is 

 more pronounced, and the hairs, especially those from the 

 inner surface of the femur, are distinctly clavate. The tactile 

 hairs of the fingers seem to be arranged as described (p. 105). 

 The j'ints are comparatively shorter and broader; this dif- 

 ference is especially marked on the hand, which is 1*G times 

 broader than the tibia and only 2'1 times longer than broad ; 

 the margins, especially the inner, are a little more convex ; 

 the number of secondary teeth of the fingers is very different ; 

 interiorly I was not able to discover any, but exteriorly the 

 immovable finger beats at least six and the movable four. 



Leys. — The hairs of the legs are more distinctly clavate ; 

 the lateral hairs near the base of the claws are more curved 

 (fig. 1/). The legs are comparatively shorter and higher — 

 for instance, the femur of the first pair of legs is only 4*4 

 longer than high. 



Colour. — The palps and maxillae are reddish brown ; the
