In this species the cephalothorax is longer, and the sides 

 more nearly parallel than usual. The quadrangle of the eyes 

 is wider in front than behind, is one-fourth wider than long 

 and occupies more tlian one-half of the cephalothorax. The 

 clypeus in the male is only a little higher than the middle 

 eyes, which are a little more than twice as large as the lateral 

 eyes of the first row. These four eyes are separated, and the 

 row is slightly curved. In the female the clypeus is about one- 

 third as high as the middle eyes, which are less than twice as 

 large as the lateral. The second row is nearer the first than 

 the third. . k 



Our specimens are so much crushed and rubbed that any 

 correct color description is impossible. Both cephalothorax 

 and abdomen are dark, much darker than the legs, excepting 

 those of the first pair in the male. The upper surface, in the 

 male, has the eye-region and the anterior central part of the 

 thorax lighter colored than the rest, and slightly tinged with 

 yellowish. Above the first row of eyes is a row of long, reddish 

 hairs extending forward, not upward. The abdomen is brown, 

 with a darker line running along each side, and a pair of dark 

 spots at about the middle point just inside of these lines. 



In the female tiie body is of rather a dark brown color, 

 while the legs are lighter with a tinge of yellow. The cepha- 

 lothorax has a light-colored line with diverging branches, on the 

 thoracic part. On the abdomen nothing is discernible except- 

 ing a central row of small dark chevrons on the posterior part. 



We have one male and one female from tlie eastern part 

 of Guatemala.
