the tip. The legs are short and clumsy, and the trochantin of the first pair of legs is 

 scarcely deeper than the femur proper, while the tibia is a trifle longer than the tarsus, 

 which is 3-6 as long as deep ; the femur of the fourth pair of legs is 2*5 as long as 

 deep, 1'2 as long as the tibia, and 1-7 lower than tarsus long. 



Colour. — The palps are reddish brown ; the cephalothorax and abdominal sclerites 

 are yellowish brown.

Palps: trochanter 0-230 (0-161) ; femur 0-414(0-175); tibia 0-414 (0-207) ; hand 

 0-407 (0-265), depth 0245 ; finger 0-299 mm. 



Leg I. : femur 0-274 (0-099), trochantin 0-061 (0-099) ; tibia 0-198 (0-072) ; tarsus 

 0-190 (0-053) mm. 



Leg IV.: femur 0-319 (0-129) ; tibia 0-266 (0-076) ; tarsus 0-220 (0-065) mm. 



Material. — Of this species I have examined a single female, infected with black 

 round bodies, perhaps spores of fungi : collected in St. Vincent by E. Simon. 



Eemarks. — This species, which is well characterised by its small size, the long, 

 strongly clavate hairs of the palps, and the short distinctly convex tibia, appears to be 

 similar to Ch.foliosus Balz., which, however, has the palps much more slender, the 

 femur being, for instance, almost three times as long as wide and of almost double 

 the size.

Male. 



Cej)Jialothorax. — Small distinct ocular spots are present. The cephalothorax, which 

 is much longer than wide, has a median fairly distinct transverse groove slightly- 

 curved backwards in the middle, and shows a trace of a hindmost one. The 

 integument is minutely granular, and the hairs are short and obtuse. 



Abdomen. — The long slender abdomen is almost three times as long as wide and has 

 all the tergites, with the exception of the first and the eleventh, longitudinally divided. 

 The sclerites are distinctly granular and with from 10-14 fairly long and slightly 

 clavate or obtuse hairs along the hindmost margins as well as generally four hairs in 

 front of the row. The eleventh tergite has a pair of " tactile " hairs. The genital 

 area has a long anterior and a short posterior plate, with a wide transverse split 

 between. 



Antennce [cf. PI. XXX. fig. 14 a). — The terminal hair extends in a slight degree 

 beyond the rather short and clumsy galea, which has six short distal branches. The 

 flagellum consists of three hairs, of which the anterior has several marginal teeth and 

 the two behind a few only (fig. 14«).
