88 PECKHAM. [Vol. 2, 



Length of large female, 14.5. 



The male is not quite mature. 



Legs in both sexes, 41 32 ; first and second pairs stoutest. 



The cephalothorax is long for this genus. The quad- 

 rangle of the eyes is one-fourth wider than long, is a little 

 wider in front than behind and occupies a little more than one- 

 third of the length of the cephalothorax. The first row of eyes 

 is straight ; the middle ej'es are sub-touching ; the lateral, a 

 little separated, the middle being less than twice as large as the 

 lateral. The second row is a little nearer the first than the 

 third. The third row is much narrower than the cephalothorax 

 at that jjlace. The falces are vertical, and moderately long and 

 robust. 



The cephalothorax is dark reddish-brown, blackish in the 

 eye region. The dorsal surface is covered with white hairs, 

 and there is a white band around the lower margin. On the 

 eye region are numerous coarse, black hairs directed forward, 

 and on each side, between the second and third rows of eyes, 

 are two bunches of black bristles. The hairs just above the 

 first row of eyes are rufous. In the female the sides of the abdo- 

 men are brown and the central portion is occupied by a her- 

 ring-bone stripe of white, edged with black. In the male the 

 entire dorsal surface of the abdomen is covered with white 

 hairs, but the herring-bone stripe may be distinguished, as it 

 is of a solider, purer white than the rest. In alcohol, the sides 

 look brown, like those of the female. The legs are reddish- 

 brown, not so dark as the cephalothorax. The palpi are red- 

 dish, the palpi and clypeus having 'man}^ long, white hairs. 

 The falces are dark brown, the under surface light brown.' 



We have one male and one female in the Smith collection, 

 from Santarem, and several females from Central America 

 (exact locality unknowii).
