236 ME, C. J. WITH ON SOUTH- AMERICAN CHELIPEEINiE 



Legl. : femur I, 0-448 (0-160), trochantin 0-106 (0-167); tibia 0-334 (0-106); 

 tarsus 0-304 (0-068) mm. 



Leg IV. : femur iv. 0-585 (0-228); tibia 0-509 (0-133) ; tarsus 0-372 (0-076) mm. 



Material. — Of this species I have examined a single badly preserved male from 

 Bogota (Keyserling's Collection). 



Variation. — Besides the specimen mentioned I have examined another male 

 from New Granada (Keyserling's Collection), which in some respects varied rather 

 considerably. The galea is longer and more slender. The maxillse slightly granular 

 in the middle. The proportions between the joints of the palps somewhat different, 

 as fenmr is 4-2 as long as wide, tibia 3-3 and hand 1-2 as long as finger; the 

 immovable finger bears anteriorly at least two " spots " in the middle, and the movable 

 finger three spots near to the ventral margin. The legs are more slender, as the tarsus 

 of the first pair of legs is at least as long as the tibia, and the femur of the fourth 

 pair is 2-8 as long as deep and 2 as low as tarsus. I give for comparison the 

 measurements of the palps: trochanter 0-368 (0-230); femur 0-966 (0-230); tibia 

 0-828 (0-253); hand 0-890 (0-368); finger 0-575. 



Bemarks. — Taking into consideration the scanty material examined, I do not consider 

 the above-mentioned differences sufficiently important to establish two species. 



From Chelifer proximus Ell. {cf. 19. pp. 324-326) this species differs only in 

 colour and the length of the finger, which is shorter, not much longer than the hand. 

 From Ch. nifus Balz. it differs in the structure of the sternal areas, in the less 

 distinctly granular maxillse, and in the less slender palps (especially femur and finger) ; 

 from Ch. canestrinii Balz. in the structure of the sternal areas and the shorter hand.

Cephalothorax. — Distinct eyes. Cephalothorax distinctly longer than wide, with very 

 broad and almost straight transverse grooves. Distinctly granular all over, with short 

 clavate hairs. 



Abdomen (PI. XXIX. fig. 5 a). — All tergites with more or less distinct longitudinal 

 line and distinctly granular; the short clavate hairs, in number from 10-14, are 

 placed along the hindmost margin, and the median and hindmost segments possess in 

 addition to these generally six hairs in front of the row. All the sternites from the 

 fourth to the tenth are longitudinally divided, and are smooth or almost so in the 

 middle, but laterally are slightly granular. In the seventh and eighth segments the 

 longitudinal line is widened out behind, and in the wide pale area so formed are situated 

 in the seventh segment two circular bodies, and in the eighth segment one (fig. 5 a).
