ences are in the color and the epigynum. The color in life is reddish 

 brown, covered with gray and black hairs and small gray scales not 

 close enough to cover the skin. The cephalothorax is a little darker 

 brown than the abdomen. The abdominal markings are indistinct in 

 some individuals, and in most entirely absent. The legs are more 

 uniformly colored than in P. rnfus, the ends of the joints being less 

 distinctly darkened. The epigynum, PI. I, fig. 2, is more distinct 

 than in nndtiformis, the dark thickened edges of the anterior opening 

 are longer and the opening is divided in front by a thick brown 

 middle line into two.

This species is known to me principally by the males. These are 

 6 or "Z'^"^ long. The cephalothorax and abdomen are bright orange 

 above and black beneath. The abdomen is covered with large 

 orange scales lighter colored than those of the cephalothorax and 

 mixed with the scales are long black hairs. On the hinder half of 

 the abdomen are two distinct black longitudinal stripes in which are 

 two pairs of white spots. PI. XV, fig. 4. These markings vary in 

 size and in one male are almost covered by orange scales. The 

 femora of all the legs and tibia of first pair are black, the other joints 

 orange brown, darker or black toward the tips. The male palpi have 

 the tibial hook flat and round at the end. Fig. 4h, 4c. 



The female which I suppose to belong to this species is 9™™ long. 

 The abdomen is covered with orange yellow scales and black hairs 

 finer and shorter than in the male. There are no black stripes. 

 Around the front of the abdomen is a white stripe. The cephalo- 

 thorax is brown covered with orange scales. The legs are orange 

 brown, the front pair darkest and the femora of all the legs darker 

 than the other joints, all of which are slightly darker toward the tip. 

 The mandibles ai'e brown in both sexes and not iridescent. The 

 sternum of the female is dark, almost black, but the abdomen is as 

 light beneath as it is above. The epigynum hafe two small openings.
