268 ME. C. J. WITH ON SOUTH- AMEBIC AN CHELIFBEINiE 



The number of ^^ spots" shows rather marked variations, at least anteriorly, where I 

 have examined a good many specimens, but their arrangement is nevertheless fairly 

 characteristic ; the immovable finger possesses anteriorly, in the area between the four 

 tactile hairs and near to it, from 15-20 " spots," while the movable finger has two or 

 three ; the immovable finger has posteriorly about six " spots " basally and a single 

 median one, and the movable finger five in the basal third. 



Coxce (PI. XXX. fig. 15 c). — The coxte of the second and third pair are both 

 widened out towards the extremity ; the second pair are rather suddenly restricted 

 towards the base and consequently the interior margin is shorter than that of the third 

 pair. The fourth ]pair, which are widened out towards the end, have the short interior 

 margin gradually merging into the posterior, almost straight one. 



Legs.— The proximal joints are indistinctly granular. Hairs of dorsal side slightly 

 clavate or obtuse and rather short ; those of ventral surface are longer, pointed, and 

 almost simple or completely so ; the tarsal " tactile " hair is at least three-fourths 

 removed from the base and distinctly longer than its distance to tip. The trochantin 

 of the first pair is scarcely as deep as the femur proper, and the tibia is almost IT as 

 long as the tarsus, which is 3-9 as long as deep. The femur of the fourth pair of legs 

 is 2'2 as long as deep, IT as long as the tibia, and 1*5 lower than the tarsus is long; 

 the tibia of the fourth pair of legs is somewhat club-shaped, being distinctly convex 

 terminally, not as usually in the middle. 



Colour. — Palps dark brown, almost black, with the stalks and extremities lighter • 

 the head, first thoracic tergite and a median spot on the second are blackish, while the 

 lateral parts of the second tergite are white. The abdominal tergites have on each side 

 a black spot near to the middle, a brown one more laterally placed, and a brown band 

 along the front margin of the tergite, connecting the two ; the rest of the dorsal surface 

 is white ; the sternites are brown and divided by a longitudinal white band. 



Measurements. — Cephalothorax 0"759 (0"736) ; abdomen 1-886 (0"989) mm. 



Palps: trochanter 0-368 (0-240) ; femur 0-690 (0-299) ; tibia 0-713 (0-322) ; hand 

 0-713 (0-515), depth 0-635 ; finger 0-529 mm. 



Leg L : femur 0-418 (0-167), trochantin 0-076 (0-160) ; tibia 0-319 (0-110); tarsfts 

 0-296 (0-076) mm. 



Leg IV. : femur 0-532 (0-243) ; tibia 0-464 (0-129) ; tarsus 0-357 (0-099) mm. 



Female. 



Abdomen (PI. XXX. fig. 15 e). — The number of hairs in the hindmost row of the 

 tergites is somewhat greater (from 12-14) and the median hair is placed more distinctly 

 in front of the row. The abdominal sclerites are not well pronounced ventrally ; a 

 large number of hairs in an elongated area in front of the sexual area (fig. 15 e). 



Antennce. — The galea extends slightly beyond the terminal hair and has three pairs 

 of distal short branches {cf. Balzan, fig. 16 a).
