Cephalothorax dark brown, black at edge, showing indistinct yel- 

 lowish markings in alcohol; the cephalic part strongly elevated with 

 an obtuse projection before the eyes densely clothed with light-colored 

 hairs which are directed upward and backward. In one specimen the 

 clypeal lobe is distinctly separated from the cephalic l^y a deep furrow, 

 while in the others either the furrow is wanting or so obscured by hairs 

 as to be invisible. All the eyes are borne on the cephalic lobe. Pos- 

 terior eyes in a straight line ; the median eyes slightly smaller than the 

 lateral, separated from them by the diameter of the latter and from 

 each other by a little greater interval; anterior eyes in a slightly pro- 

 curved line; median eyes slightly smaller than the lateral, subcon- 

 tiguous and separated from the lateral by their diameter. Median 

 ocular area as long as wide and slightly narrower in front than behind. 

 Clypeus much wider than ocular area. Sternum dark brown. Abdo- 

 men somewhat flattened, projecting over the cephalothorax and cov- 

 ered almost entirely by a dorsal sclerite which is dark brown, showing 

 a reddish tinge in alcohol, punctulate and sparsely clothed with stiff 

 hairs; sides and ventral surface of abdomen black and grayish-yellow 

 in indistinct patches. In one specimen which is very light the dorsal 

 sclerite is scarcely evident. Ventral sclerites indistinct, dull yellowish- 

 gray. Sternum as long as wide, smooth, yellowish-brown, posterior 

 point a little narrower than the length of fourth coxa. 



Chelicerse dark brown, yellowish on the inside near the tip, upper 

 margin of the fm-row with five teeth, first four contiguous, fourth the 

 largest and separated by nearly its length from the fifth ; lower margin 

 with four or five small teeth. 



Legs brownish-yellow, lighter on the patellge; spines on tibiae short, 

 on fourth leg situated near the middle of the joint. Lower side of 

 femora armed with two series of spines. Femur of the palpus cylindri- 

 cal, the patella short and thick; the tibia provided with a rectangular 

 projection on the upper outer side which bears on its outer side a strong- 

 curved hook and along its edge a row of tubercles surmounted with 

 black hairs.
