The male is exceedingly slender. The eyes of the first 

 row are twice as large as those of the second, the second row 

 being wider than the first. The falces of the male are long 

 and obliquely directed, diverging after the first third, with a 

 long fang. The palpus has the tibia longer than the patella 

 and these two joints together nearly as long as the tarsus. 

 There is a stiff bunch of hairs on the upper side of the distal 

 end of the tibia. The distal half of the metatarsus of the first 

 leg is slightly darkened, and has a very scanty fringe of hairs 

 on each side. 



The female has the falces vertical and stout, with short 

 stiff hairs growing over the front face. The fang is long and 

 slender. The clypeus is higher than in tlie male. 



The spider is pale yellow with a central dark line on the 

 thoracic part. There are some red and white hairs left on the 

 cephalic part. The clj^peus is covered with red hairs in the 

 male and with white hairs in the female. The first eyes are 

 white, the others black. 



We have a male and a female from Panama, and a female 

 from British Honduras.
