Length, S 4.3 mm., $ 5.5 mm. Legs, 6 $ 3142, the first 
pair but little stouter than the others. In the male the legs o£ 
the first pair are fringed and those of the third have an enlarge¬ 
ment on the patella. Spines, S tib. I 1 pair and 2 behind on 
the posterior side, while in front are 2 not very heavy spatu- 
late spines and 1 anterior lateral; tib. II 1 pair and 2 seri¬ 
ally behind, and 3 anterior laterals; pat. I 1 anterior lateral, 
pat. II 1 anterior lateral and 1 posterior lateral; met. I 2-2, 
met. II 2-2 and 2 anterior laterals. 
In the male the cephalic plate is covered with hairs of 
a soft fawn-color tinged with red, and is bordered, behind, by 
a scalloped, yellowish-white band. The upper sides of the ceph- 
alothorax and the middle of the thoracic slope are velvety black. 
A wide white band runs back from each dorsal eye to the poster¬ 
ior margin, and then curves forward and passes along the lower 
side to a point opposite the dorsal eye. The abdomen is velvety 
black with central and encircling white bands, and a pair of 
white dots above the spinnerets. The encircling*band sends up 
an oblique bar on each side, and the central band is enlarged 
and notched in the middle. The first legs, in life, are of a tender 
green color, the others, yellowish with white scales. The first 
has, on the outer under side of the femur, a thick fringe of 
white, continued in a thin fringe which is short on the patella 
and long on the tibia. The tibia has also some long white hairs, 
and two black spines on the inner side. The third leg has the 
patella enlarged at the distal end, and has a short curved apoph¬ 
ysis which extends over the tibia. The front face of the en¬ 
larged part is pale and on it is a small black spine. This is 
evidently in the nature of an ornament since it is used in display 
during courtship. The clypeus and the front of the falces are
