The eyes, which are unequal in size, are disposed in front 

 and on the sides of the anterior part of the cephalothorax ; 

 four, much smaller than the rest, form a transverse row im- 

 mediately above the frontal margin, the two intermediate ones 

 being rather larger than the lateral ones of the same row ; the 

 other four describe a trapezoid, the two anterior ones, which 

 are the largest of the eight, forming its shortest side. The ce- 

 phalothorax is long, compressed before, depressed and rounded 

 on the sides and at the base, sparingly clothed with hairs, and 

 of a dark-brown colour, with a broad yellowish-grey band ex- 

 tending along the middle, and narrow white lateral margins. 

 The falces are long, powerful, subconical, and vertical ; the 

 maxillffi are straight, and increase in breadth from the base to 

 the extremity, which is rounded ; the lip is somewhat qua- 

 drate, being rather broader at the base than at the apex. These 

 parts have a reddish-brown colour, the maxillje and apex of 

 the lip being much the palest. The sternum has a short oval 

 form ; it is convex, glossy, provided with long, upright, black 

 hairs, which are most numerous on its sides, and has a very 

 dark-brown hue. The legs are long, provided with hairs and 

 sessile spines, and are of a red-brown colour, the femora being 

 much the darkest ; the fourth pair is the longest, then the 

 is of a dark-brown colour, and there are several obscure pale-
