Length, 8 4.7 mm., 9 5.5 mm. Legs, 8 1423, first plainly 
longest and stoutest, with enlarged femur; 9 1423, first not 
much longer than fourth, but stouter than in 8 . Spines, 8 9 
tib. I 2-2 at distal end (rarely a fifth spine below, further 
back), met, I 2-2. 
There is a marked difference between the two sexes in the 
shape of the cephalothorax. While in the male the anterior 
thoracic part is flat, and is on a level with the cephalic, and the 
posterior slope abrupt, in the female, the thoracic part rounds 
off gently from the dorsal eyes to the posterior border. The fal- 
ces are vertical; the lip as wide as long, and the sternum is 
small and oval. 
The coloring is very brilliant. The upper surface of the ce¬ 
phalothorax and the upper and under surfaces of the abdomen 
are covered with iridescent scales, the prevailing colors of which 
are pink and gold. The upper sides of the cephalothorax are 
covered with iridescent scales, which are white with greenish 
reflections. The clypeus and lower sides have snow-white bands, 
which are pale yellow in the four pairs. At the union of these 
two joints is a black ring and the tarsi are tipped with black. 
The palpi are pale brown in the female, and dark brown in the 
male, and are covered with white hairs. 
We have this species from Kansas, Arizona, Kew Mexico, 
Texas and California.
