24 PECKHAM. [Vol. 3. 



In the male palpus the tarsus, taken alone, is nearly as long 

 as the patella, and is much longer than the tibia. The palpus, 

 as a whole, is shorter than in fallax. The female also has a 

 long slender white palpus. 



The general color of the male is pale brown, the cepha- 

 lothorax being tinged with yellow. All of the eyes are sur- 

 rounded by short brilliant red hairs. The front view is very 

 picturesque, as there is a snowy-white tuft of hairs in the mid- 

 dle of the front part of the eye-region, in front and on the 

 sides of whicli are upright red hairs, while the clypeus has a 

 large patch of white hairs in the middle. The lower part of 

 the clypeus is not blackish, as in fallax, but is of a pale brown 

 tint, differing from the upper part, which is tinged with red. 

 The abdomen has a pair of round dark spots near the anterior 

 end, just in front of which is a curved band of Avliile hairs. On 

 the posterior part are two pairs of angular dark spots, in front 

 of and in line with which is a pair of white spots. The dark 

 spots are separated by a central band of white hairs, and there 

 are some white hairs on the lower sides. The legs and falces 

 are yellowish, like the cephalothorax. 



In the female the cephalothorax and legs are of a deeper 

 tint than the abdomen, which is of a clear pale yellow. There 

 are red and white hairs around all the eyes. The clypeus is 

 yellow with a horizontal line of white hairs a little way below 

 the eyes. The anterior part of the abdomen has two dark 

 spots with a curved white band in front, as in the male, but 

 the posterior part has some figures in black which are very 

 variable in shape, sometimes consisting of a series of dashes and 

 spots and again appearing as is shown in the figure. 



We have one male and three females, sent by Count Key- 

 serling, from Panama, /a ?faa; coming from the same localit}^
