curved and provided with a single anterior tooth near to their base. The dorsal 

 "lactile" of the fourth pair is placed nearer to the tip than to the base. The femur 

 of the fourth pair of legs is about 3 times longer than deep; the tarsus of the first 

 pair of legs is as long as the tibia and that of the fourth pair of legs is l? longer 

 than the femur is deep. 



Colour. — The head and the first thoracic tergite as well as the palps, with 

 the exception of the lighter trochanters and fingers, are blackish brown ; the second 

 thoracic tergite is yellowish with a blackish spot in the middle and a while one 

 on each side. The first abdominal lergites are brownish, but the last ones are 

 darker brown ; the articulate membranes and rest of the body more or less 

 yellowish. 



Measurements. — Céphalothorax 0784 (0750 hindmost margin of shield; 

 0-924 real breadth is specimen dilated with eggs); abdomen 1562 (1008) mm. 



Palps: trochanter 0364 (0210); femur 0588 (0235); tibia 0588 (0270); hand 

 0-560 (0-364), depth 0420; finger 0540 mm. 



Leg I: femur 0390 (0144), trochantin 0180('?); tibia 0279 (0-090); tarsus 

 0-279 mm. 



Leg IV: femur 0558 (0189), trochantin 0234; tibia 0405 (0108); tarsus 

 0333 mm. 



c?. The genital area seems to be similar to that of Ch. cimicoides F. The 

 galea is shorter than in the female. The coxa of the fourth pair is more 

 distinctly widened out towards the end and has the anterio-interior corner more 

 pointed. 



Material. — I have examined Simon's original specimens, found under bark 

 of cocoa-nut palm (3 Ç and 1 c?), Kuala Aring (Kelantan), in the month of Sep- 

 tember 1899. 



Remarks. — I have redescribed this species, though Simon has given a 

 good and concise description of it, because several structures of importance have 

 not been taken into consideration by this naturalist, and because it is my aim to 

 include all facts of importance, published up to the present lime, as far as the 

 natural history of Ihe Indian species of this order is concerned , in this paper. 

 This species must certainly be regarded as akin to Ch. nodosus Schranck in spite 

 of the wanting (?) accessory teeth of the lingers of the palps.

 (PI. IV, fig. 3 a). 



Ocular spots obsotete ; céphalothorax much longer than broad milh rather indi- 

 stinct transverse line curved backwards in the middle: sl<in almost smooth ivith slender

 tudinally depressed in the middle and the median provided with a distinct narrow
