tibia is 1*3 as long as the tarsus, which is 3-5 as long as deep ; i\iQ femur of the 

 fourth pair of legs is scarcely 2'2 as long as deep, 1*2 as long as the tibia, and 1*1 

 lower than the tarsus is long. 



Colour. — The palps are reddish brown.

Material. — Of this species I have examined a single damaged specimen ( ? ) from 

 New Granada (Keyserling Coll.) ; the typical specimen is from Venezuela. 



Memarks. — That the described specimen belongs to Ch. suhrobustus Balz., I regard 

 as quite certain, as the differences are only trivial ; it differs from Ch. robustus Balz. 

 by the less slender femur and tibia and from C/i. gracilis Eil. by the granular 

 cephalothorax and less slender hand. 



c. Subgroup of Chelifer bicolok Balz. 



Flagellum consists of three hairs. Cephalothorax generally with ocular spots and two 



transverse grooves. The hand seldom much longer than the tibia. The tarsal 



" tactile " hair is more than one-fourth removed from base. 



This group contains species which in many respects differ greatly among themselves. 



It includes, in fact, all those which cannot be naturally placed in any of the three 



preceding groups. Nevertheless, several of the species show close relationship to each 



other : Ch. bicolor Balz., Ch. subrudis Balz., &c., are nearly related to each other, 



showing similarity in the structure of the male genital organs, in the shape of the 



palps, and the colour of the second thoracic tergite ; Ch. patagonicus Tullgr. and 



Ch. ellingsenii, sp. n., are nearly related to each other as well as to Ch. elegans Balz., 



referred to the following subgroup.

Cephalothorax minutely granular, with two transverse grooves. Abdomen with long 

 pinnate hairs along hindmost margin and six in front. The hairs of palps dentated or 

 pinnate ; the femur at least 3 as long as wide ; tibia, which is about 2-5 as long as 

 wide, has moderately convex outlines. Hand, which is scarcely longer than finger, of 

 a most remarkable shape, being provided with three conical protuberances. — Amazons 

 and Peru.
