 scales and some black hairs. Femur of the first with a distinct tuft 

 of stiff black hair on the under side. Patella of the first with a small, 

 and tibia of the first with a much larger tuft of stiff black hairs on 

 the upper surface. $ . Cephalothorax covered with gray liaks. Ab- 

 domen covered with gray hairs, with a basal band, two oblique bands 

 on each side, two spots near the apex, and a central line of chevrons

Cephalothorax high, shgiitly convex behind, dilated in the middle, with 

 sides rounded niore widely behind than in front; cephalic part plane, 

 not inclined; thoracic sloping slightly in the first half, then more 

 steeply. Ocular area occujjying two-fifths of cephalothorax, not

 half as large as middle eyes and a httle separated from them ; eyes of 

 second row half way betAveen lateral and dorsal eyes; dorsal as large 

 as lateral eyes, further from each other than from lateral borders,
