244 ME, C. J. WITH ON SOUTH-AMERICAN CHELIFEEIN^ 



Leg I.: femur 0-334 (0-137), trochantin 0-076 (0'129); tibia 0-258 (0-084); 

 tarsus 0-243 (0-053) mm. 



Leg IV.: femur 0-426 (0-217); tibia 0-365 (0-106) ; tarsus 0-274 (0-068) mm. 



Variation. — Another, probably a young male, was distinctly smaller, had the 

 posterior margin of the abdominal tergites more regularly serrated ; the hand 

 comparatively narrower, and the space left between the fingers when closed much 

 smaller; fingers comparatively shorter. 



Female. 



Cephalothorax. — The transverse grooves are less prominent and the anterior appears 

 more curved backwards, as it is laterally directed forwards. 



Abdomen. — The abdomen appears less slender, as it is scarcely twice as long as 

 broad. The tergites show no trace of serrated posterior margin ; the longitudinal 

 line is not visible in the first three and the last tergites, and is only slightly pronounced 

 in those between. The tergites are not very distinctly granular and have a greater 

 number of hairs along the hindmost margin, viz., about 14; the eleventh tergite has 

 a pair of long slender " tactile " hairs. 



Antennce. — The exceedingly long, slender, cylindrical galea, which has about six short 

 terminal branches, extends very much beyond the terminal hair {cf. lo. fig. 13 5, $ ). 



Palps. — The hairs are perhaps somewhat shorter than in the male. Anteriorly the 

 twcfianter is slightly and regularly convex, posteriorly less distinctly bigibbose than 

 in the male. The femur, which is more distinctly widened out towards the end, is 

 3*2 as long as broad ; anteriorly beyond the stalk it is almost completely straight. 

 The tibia is shorter than the femur and 2-4 as long as wide. The hand, which is 

 only a little shorter than, but 1-4 as long as the tibia, is 1-6 as long as broad, a little 

 wider than deep, and 1-2 as long as fingers, which scarcely gape when closed ; " spots " 

 anteriorly are arranged almost as in the male. 



Coocw (PI. XXIX. fig. 7jii").— The fourth pair of coxte are of a 

 more quadrangular appearance, as they are only in a slight degree ®^ " S- 



widened out towards the end, and the interior margin is fairly long 

 and well defined from the concave hinder one ; the postero-exterior 

 corner is scarcely produced. 



Legs (text-fig. 65).— The femur of the fourth pair of legs is less 

 abruptly raised beyond the stalk, is more slender, viz., 2-2 as long 

 as deep, 1-1 as long as tibia, and 1-5 lower than tarsus long. 



Colour. — Colour of the cephalothorax, but especially of ' the 

 yellowish abdomen, much lighter. Ch. segmentiden- 



Measurements. — Cephalothorax 0-575 (0-414); abdomen 1-104 tatus Balz., §.
