from each other and from honduremis and centralis by their 

 peculiar falces. Capiiatus, centralis, - dubitabilis and hondurensis 

 differ from each other in the shape of the cephalothorax.

 cephalothorax, 1.4. 



The male is a little smaller, but with the same pro- 

 portions. 



Legs, S 1432 ; ? 1423 ; first pair stoutest. 



The shape of the cephalothorax differs a little with the 

 sexes. In the male the upper surface is almost level, excepting 

 a slight elevation at the dorsal eye, from the second row of eyes 

 through half the length of the thoracic part, falling steeply both 

 in front and behind. In the female the cephalic and thoracic 

 jjarts slope in opposite directions from the dorsal eyes, at first 

 very gradually and then more abruptly, the final fall being 

 less steep than in the male. The falces are vertical and mod- 

 erately long and stout, being stouter and more convex in front 

 in the male than in the female, but still not visible from above 

 as in rv,ber and nitidus. 



The general color is brown, the male being darker than the 

 female, and in both sexes the cephalothorax is darker than the 

 abdomen. In the female the whole body is covered with gray 

 hairs. On the dorsum of the abdomen are four pairs of black 

 spots, edged Avith white, those of the posterior pair being indented 

 on the inner sides. The hairs are usually all rubbed off in pre- 

 served specimens, and when this is the case the appearance of 

 the abdomen is much changed, the integument being of a light 

 brown color, streaked and spotted with a paler shade, with two 

 hairs of pale colored or white spots on the anterior part, and 

 two pairs of oblique pale bars on the posterior. The legs are 

 light brown, barred with darker, with some close white scales.
