$ . Total length 11.5 mm. Width of abdomen 4 mm. 



Cephalothorax: length 5; width 4; height 2.5. 



Legs 9.6, 7.5, 8, 10; patella and tibia of the first 4; patella and tibia of the 

 third, 3.4; patella and tibia of the fourth 4; metartarsus and tarsus of 

 the fourth, 3.8. 



Lateral eyes of first row one-half as large as middle eyes and separated 

 from them by one-third their own diameter. ClyiDeus one-half as 

 high as middle eyes. Maxillae enlarged and rounded at extremity. 

 Labium two-thirds as long as maxillae. Falces nearly as wide as 

 first row of eyes, as long as face, vertical, diverging. Sternum, very 

 deepset, oval, projecting between the anterior coxae which are 

 separated by the width of the labium. 



Coloration: A wide band of white hairs extends across the clypeus and 

 on to the sides, under the eyes, nearly encircling the cephalothorax; 

 above is a black band which occupies the cephalic part, but grows 

 narrower on the thoracic, where the white band curves upward. On 

 each side of the cephalothorax are two tufts of black hairs, one be- 

 tween the eye of the second row and the dorsal eye, and one just be- 

 hind and below the anterior lateral eye. Abdomen black with a 

 band of long white hairs at base, and several lines of white hairs on 

 each side; on the anterior part of the dorsum are two white dots; on 

 he middle part and nearer together, are two larger white spots; near 

 the apex are two large curved spots of a light yellowisli red color; 

 these with the white spots, and the lines on the sides mark off a some- 

 what irregular black figure on the posterior part of the dorsum. 

 Falces darkly iridiscent with a fringe of white hairs at their inser- 

 tion. Palpi and legs black with long white hairs. Mouth-parts, 

 sternum, coxa? and venter black, the venter nearly encircled by 

 wliite hau's which form wide white bands on the sides, and with 

 two white spots in the middle . 



This is a very hairy species, in this respect, and in its general color- 

 ing, resembling P. galathea. 



Habitat: Georgia, Alabama.
