can say little about its color and marking. It is a small, deli¬ 
cately made spider, the cephalothorax large in proportion to the 
abdomen. The ground color is dark brown, with white hairs 
over the front, eyes, on the sides of the cephalothorax, and the 
front end of the abdomen. The clypeus is light fawn. The 
legs are light brown with some darker cloudings, the first heavily 
and the second lightly fringed with white. On the upper sur¬ 
face of the femur of the first are three small dark points. The 
third leg is simple. 
One male from Arizona.

8 . Length 4.5 mm. Legs 3412, first slightly stoutest, with a 
ridge of short, stiff brown hairs under patella and tibia and a 
small bunch of stiff reddish hairs at the distal end of the outer 
side of the femur. The spines are transparent white, and diffi¬ 
cult to see and are very long. There are two pairs and an an¬ 
terior lateral on metatarsus, and one anterior lateral on tibia 
and on patella of first and second legs. 
The cephalothorax is deep black covered with pure white hairs 
excepting a yellow stripe on each side under the eyes, and a yel¬ 
low band on the middle of the thoracic part. The front eyes are 
ringed with red, and the clypeus is white with a bunch of long 
tawny red hairs in the middle. The abdomen is covered thickly 
with long scales, white at the base, reddish-golden on sides and 
back. There is a spot of white scales (as wide as long) in front 
of the middle, which may originally have been differently col¬ 
ored. The tarsi and metatarsi are light yellow; otherwise the 
legs are brown, the first pair much the darkest, thickly covered 
with snow-white scales. The palpi are brown with white scales, 
the tarsi covered with long white hairs.
