and stand out prominently. They are large and close together, 

 and form an almost straight line, the middle being nearly 

 twice as large as the lateral. The quadrangle of the eyes is 

 but little wider than long, is wider in front than behind, and 

 occupies two-fifths of the cephalothorax. The second row of 

 eyes is nearer the first than the third row. The dorsal eyes 

 are somewhat larger than the lateral and are placed on the 

 side of the cephalothorax. Behind the dorsal eyes is a wide, 

 shallow constriction. The pedicle is barely visible from above. 

 The long and rather slender abdomen has a faint constriction 

 in front of the middle. The falces are vertical, robust and 

 rather long, and have their anterior faces slanting inward from 

 the outer to the inner edges. 



Color. The integument is deep reddish-brown, and is 

 slightly iridescent, especially in the abdomen. Around the 

 anterior eyes, on the clypeus, and on the outer side of the 

 falces are some long, white hairs ; the rest of the cephalothorax 

 and the abdomen are thinly covered with rather long, j^ellow- 

 ish hairs; the abdomen has two transverse bands of white 

 hairs, one near the anterior end and a second at the constric- 

 tion. The legs are of rather a light reddish-brown color with 

 darker longitudinal bands on the inner and outer sides of the 

 femoral joints. The palpus has the femur light reddish-brown 

 and the other joints much darker, almost black. The under- 

 surface is all reddish-brown, the coxEe being a little lighter 

 colored than the sternum. 



Habitat. Rio Janeiro.

Cephalothorax long, moderately high ; cephalic part on a 

 much higher plane than thoracic. Cephalic part inclined 

 forward. Thoracic part convex. Quadrangle of eyes very 

 slightly wider than long, a little wider in front than behind, 

 occupying not quite two-fifths of the cephalothorax. Anterior 

 eyes, with their upper edges in a straight row, subtouching; 

 middle more than twice as large as the lateral and standing 

 out much beyond thein. Second row plainly nearer the first
