is 2<S longer Ihaii decj). The tdisiis ul' Ihe lirsl [y.ni uf legs is a little shorter than 

 the tibia and 47 longer than deep, and that ol" tlie fourth pair is almost twice as 

 long as the femur is deep; the clams are simple. 



Colour. — The palps and the céphalothorax are light hrown; the abdominal 

 lergites are lighter, more yellowish brown; the remaining part of the body is pale 

 yellowish. 



Measurements. — Female dilated with eggs. Céphalothorax 0784 (ÜB72); 

 abdomen 3-320 (1-540) mm. 



Palps: trochanter 0420 {0224); femur 0700 (0240); tibia 0-675 (0-270); hand 

 0-685 (0-364), depth 0336; finger 0514 mm. 



Leg 1: femur 0-468 (0-170), trochantin 0135; libia 0360 (0095); tarsus 0-340 

 (0-072) mm. 



Leg IV: femur 0603 (0210), trochantin 0235; tibia 0558 (01 10); tarsus 0423 

 (0-085) mm. 



c?. Body (PI. Ill, fig. 7 b). — The transverse stripes, which are broader than 

 in the female, and the granulations of the céphalothorax as well as the longitudinal 

 line of the abdomen and the white spots, in which its hairs are placed, are more 

 prominent than in the female on account of the darker colour of the body. The 

 genital area is not very prominent with the anterior plate shorter than the posterior, 

 which just behind the opening bears a number of short pointed granules (PI. Ill, 

 fig. 7b, sp)^). Each of the following sternUes (IV— IX) is provided with a number 

 of short, strong and well articulated spines, varying in number from 40 on the 

 fourth sternite and 60 on the ninth to 100 on those between; the area, which is 

 mounted with the spines, occupies in the median segments on each side the inner 

 posterior part of each sternite, being two thirds as long as the latter and only half 

 as broad. Very short fissures, placed within a round area, are found in conside- 

 rable number especially on the eleventh tergite as well as on the two last sternites, 

 each bearing about 40. 



Antennae. — The flagellum consisted in one specimen of four hairs as in 

 the female, but it consisted in another of five hairs, of which the anterior was 

 gradually enlarged towards a little in front of the tip with about six marginal 

 teeth, while the two posterior ones were very short. The galea, which is scarcely 

 extended beyond the terminal hair, is slightly broken in its distal third and here 

 provided with a number of very short teeth. 



Palps (PI. HI, fig. 7 e). — The palps are longer and more slender than in the 

 female, and a little longer than the body. The trochanter has the dorsal posterior 

 tubercle more prominent than in the female; the femur has the anterior basal 



') Spinous areas of a similar or not verj' different structure are found on tlic median sternites 

 (VII — VIII at least) of the male in a number of South-American species, which show similarity to Ch. 

 siibruber Sim. in the structure of the articulation between the trochantin and the femur proper in the 

 first pair of legs as well as in other respects, viz. Ch. riifiis Balz., Ch. Caneslrinii Balz., Ch. longichelif'er 

 Balz, and Ch. scymenlidenlalus Balz. (cf. foot-note on p. 129).
