274 MR. 0. J, WITH ON SOUTH-AMERICAN CHBLIFERIN^ 



posteriorly the immovable finger has ten spots and the movable about twelve in the 

 middle. 



Coxw. — The coxse are almost the same as in Ch. hicolor Balz., the only difference 

 being that the third pair have the anterior and inner corner produced into a short 

 blunt process (cf. fig. 15 e). 



Legs. — The proximal joints are granular. The hairs of the dorsal surface are 

 moderately long and slightly clavate or obtuse, those of the ventral side are generally 

 pointed and simple, seldom dentated and obtuse. A tarsal " tactile " hair, a little 

 longer than its distance to the tip and three-fourths removed from the base, is found. 

 The legs are fairly long and slender ; the trochantin of the first pair is much deeper 

 than the femur proper ; the tibia is of almost equal length with the tarsus, which is 

 five times as long as deep. The femxir of the fourth pair of legs is almost three times 

 as long as deep, I'l as long as tibia, and about 2-2 lower than the tarsus is long. 



Colour. — The palps are dark brown and so is the cephalothorax, with the exception 

 of the second tergite, which only has a small triangular black spot in the middle. 

 The abdominal tergites are light brown with the longitudinal band and a spot on each 

 side yellowish. 



i¥effs«reme«fo.— Cephalothorax 0-920 (0-805) ; abdomen 2-070 (1-380) mm. 



Palps : trochanter 0-483 (0-322) ; femur 0-805 (0-345) ; tibia 0-828 (0-391) ; hand 

 0-828 (0-552), depth 0-565; finger 0-713. 



Leg I. : femur 0-578 (0-175), trochantin 0-122 (0-195) ; tibia 0-433 (0-114) ; tarsus 

 0-426 (0-084) mm. 



Leg IV. : femur 0-707 (0-243) ; tibia 0-646 (0-140) ; tarsus 0-517 (0-095) mm. 



Variation.- — The other specimen which was examined only differed by the number 

 and arrangement of the " sijots " ; anteriorly the immovable finger has either one or 

 two " spots " behind the basal hairs, and two behind and one beyond the terminal 

 hair; posteriorly the most important differences are that the immovable finger has 

 only two " spots " beyond the median hair, and that the movable seems only to possess 

 five spots. 



Material. — Dr. Meinert obtained two females by sifting in the month of August, at 

 La Moka. This species had previously been collected in Paraguay and Brazil (Matto 

 Grosso). 



Bemarks. — It is with the greatest hesitation that I have referred the above-described 

 form to Ch. crassimanus Balz., as the hand is only 1-4 instead of 1-6 as wide as the 

 tibia, and 1-2 instead of 1-4 longer than the fingers ; from Ellingsen's description it 

 differs besides by the maxillse, which are not smooth, and by the tibia, which is not 

 nearly smooth below. The only one of the mentioned characters which would justify 

 the establishment of a new species is the longer fingers ; but as the fingers of the 

 male are only a little shorter than the hand, I think it better not to establish a new 

 species. From the two preceding species, Ch. crassimanus Balz. differs by shape of 

 the femur and its hairs as well as by its colour.
