part slopes quite steeply to the posterior margin. Quadrangle 

 of eyes one-fourth wider than long, plainly wider in front than 

 behind, occupying one-half of the cephalothorax. Anterior 

 eyes in a straight row, all touching ; the middle eyes bulging 

 out, and more than twice as large as the lateral. Second row 

 about half-waj'^ between first and third rows. Third row as 

 wide as cephalothorax at that place. Falces moderately long, 

 vertical, parallel, rather weak. Lip wider than long. Coxee i 

 separated by more than width of lip. Sternum rather large, 

 oval, a little wider in front than behind. Pedicle rather long. 

 Abdomen rounded, widening out behind the middle. 



Color. The general tint is very much lighter than in 

 ruficeps. The cephalothorax is reddish-brown, with which 

 color the black, which surrounds all the eyes, makes a contrast. 

 There are some traces of silvery down on the sides. The abdo- 

 men is light brown, and, like that of ruficeps, is encircled in 

 the middle by a white ring, interrupted in the middle of the 

 back. In this species, however, it does not extend across 

 the venter. The legs are light brown, with a longitudinal 

 black line running along the anterior surface of the patella, 

 tibia and metatarsus of the first. The palpi are darker than 

 the legs. The falces, sternum and mouth parts are light 

 brown, or reddish. 



The greater size of the middle eyes of the first row, in 

 proportion to the lateral eyes, distinguishes this species from 

 ruficeps.
