is longer Ihan broad and posteriorly "forlissinie rotundata vel pofius gihbosus"; 

 the femur, which is a little broader than the trochanter, is a little more than twice 

 as long as broad; the tibia, which possesses a rather long and slender stalk, is a 

 little shorter and broader than the femur and beyond stalk "pulchre ovatuni". 

 The hand, which is distinctly broader and a little longer than the tibia, is much 

 broader than deep and 1-5 longer than finger. The abdominal tergites are dark- 

 brown ("picea") with lighter spots for the hairs. Thorell's original specimens of 

 this species are from Java. 



It .seems to difTer from Ch. plebejus n. sp. by the granulation of the palps, by 

 the less distinctly convex lateral outlines of the tibia as well as by its more slender 

 stalk, and by the darker colour of the abdominal tergites (cf. p. 187); but it is 

 similar to this species and different from the other Indian species of the "Ch. Bir- 

 manicus Thor." group by the trochanter, the dorsal surface of which is scarcely 

 produced posteriorly. This species has been mentioned by Pocock from Christmas 

 Island; but the specimen, determined by this naturalist as Ch. Javanus Thor., is 

 rcallj' an undescribed species, differing from the latter by the structure of the 

 trochanter of the palps. Simon calls this species "très répandue en Malaisie", but 

 he is probably wrong in regarding Ch. Jcwanus Thor, as a common form, for the 

 specimens of the Skeat Expedition, which he referred to this species, seem reall}' 

 to belong to another species viz. Ch. plebejus n. sp., which has a very wide range 

 (cf. p. 187).

Imlistincl ocular spots: céphalothorax sliyhtlij longer than broad behind, without 

 transverse line, almost smooth with rather long and slender, -almost simple hairs. The 

 long and slender abdomen has on the median tergites 6 (^) hairs in front of the row 

 and terminalli) "tactile" hairs. (^) Genital area of "Birmanicus" type. Tl\e com- 

 pletely sniooth palps are shorter tluin the body; trochanter distinctly longer than broad, 

 with posterior margin abruptly convex, and dorsal surface scarcely produced; femur 

 22 longer than broad, scarcely as long as but distinctly narrower than the tibia, 

 which has lateral outlines distinctly conve.v and posterior based elevation almost obsolete. 

 The hand is i A broader than tibia, about 1-6 longer than broad, 1-7 longer than deep 

 and li longer than finger. "Tactile" hair of the fourth tarsus is placed at the base; the 

 tibia of the first pair is a little longer than the tarsus, which is 3-6 longer than deep. 



Ç. Céphalothorax. — Two very indistinct ocular spots present. The céphalo- 

 thorax is a little longer than broad behind, where it is broadest, and shows no trace 

 of transverse division ; it is almost smooth and provided with rather long hairs, 

 which bear a few terminal teeth. 



Abdomen. — The abdomen is twice as long as broad with parallel sides and 

 of a rather slender appearance; the tergites, at least from the fourth to Ihc tenth,
