front of the second row. The falces of the male are very long, 

 horizontal, and have the distal third much enlarged ; in the 

 female they are vertical and only moderately long and .stout. 

 The fang, in the male, is as long as the falx. The pedicle is 

 very long and has two joints. The abdomen is oval and has a 

 constriction in the anterior third. The sternum is long and 

 narrow. The lip is longer than wide. The legs are very long. 



Color. Cephalothorax and pedicle light yellow with a 

 tinge of red ; iipper .surface of eye-region bright and glisten- 

 ing ; eyes black. Falces colored like the cephalothorax, except- 

 ing a blackish spot at the insertion of the fang, and blackish 

 lines along the inner edges on the under surface. Legs yellow, 

 excepting the trochanter of the fourth, which is pale. Abdo- 

 men dull brown with a yellowish patch on either side of the 

 constriction ; the constriction itself is pale. Venter drab ; .ster- 

 num, coxffi and mouth parts, yellow. 



The abdomen of the female sometimes shows light chev- 

 rons on the posterior j^art, and all her colors are duller than 

 those of the male. 



Habitat. Cejdon. 



Cambridge says of this species : " The spiders themselves, 

 although adult, differ greatly in size, some being larger than 

 that above described, and others at least one-third smaller. 

 The falces also vary considerably in the relative length in 

 different specimens, in one rather exceeding the length of 

 cephalothorax and pedicle connecting it with the abdomen, in 

 another only just equalling the length of the cephalothorax."
