Plate ^'l, figs. 5-5a. 



Our only specimen of this species has the front part of the 

 cephalothorax broken so that the shape is uncertain, and we 

 therefore have not put it into any closely defined genus. The 

 clear marking of the abdomen, however, should make it easily 

 recognizable. 



9 . Length, 6. Length of ceijhalothorax, 3 ; width of 

 cephalothorex, 1.8. 

 Legs, 4312 ; the first pair being a little the stoutest. 



The cephalothorax is not high, and seems to have had the 

 upper surface level from the anterior eyes through the first 

 third of the thoracic part, with the exception of a slight hump 

 above the dorsal eye. The anterior eyes form a straight row, 

 the middle being twice as large as the lateral. The second 

 row is half-way between the first and third. The third row is 

 slightly narrower than the cephalothorax at that place. The 

 cephalothorax is long, and the cephalic part occupies a little 

 less than two-fifths of it. 



The color of the cephalothorax is yellowish-brown, the 

 eye-region being a little darker than the rest. There are some 

 yellowish-white hairs on the sides below the second and third 

 rows of eyes, and around the lower margin. The abdomen is 

 pure white with two black longitudinal bands which meet in 

 front and behind. On the outer side of each of these, near the 

 posterior end, is an oblique line of white, directed backward. 

 On the lower sides are some slender black lines formed by 

 hairs. The first leg has the femur pale, and the other joints 

 yellowish brown. The other legs are all pale, with fine black 

 spines. 



We have one female from Panama, sent to us by Count 

 Keyserling.
