being white, are all copper-colored and similar hairs thinly cover 
the whole cephalothorax. The pattern is comparatively indis¬ 
tinct. The clypeus is plainly banded, dark bars separating the 
white middle part from the white on the sides. The peculiar 
sternum and venter are present. A young female taken at the 
same time is also copper-colored, but has the band running back 
from between the anterior middle eyes, white. 
In the male the color varies. Our specimens from Hew Mex¬ 
ico and Utah, have the cephalothorax brown, the eye-region be¬ 
ing covered with yellowish-gray hairs. The upper sides of the 
cephalic part, and the sides of the clypeus, are covered with 
short white hairs, but the middle of the clypeus has long yellow 
or tawny-red hairs. White marginal bands begin opposite the 
small eyes of the second row; before reaching the end they turn 
up over the back, and pass forward, becoming indistinct and 
blending with the yellowish color of the cephalic plate. The 
abdomen is dark with a covering of reddish-gray hairs. There 
is no basal band, but two white bands start near the front end, 
passing obliquely down the sides, and in front of the spinnerets 
is a row of tiny white chevrons, as in the female. The first leg 
is highly decorated. The lower face of the femur is iridescent 
bluish-green edged on the inner side by a white band, and on 
the outer by short thick white fringe. Below the patella is a 
mass of stiff dark hairs which curve inward. Above the tibia, 
along the inner edge is a stiff ridge of dark hairs with a bar of 
peacock-green on their tips and a bristly tuft near the proximal 
end, while below is a long soft white fringe which is overlapped 
on the inner side, and to some extent on the outer side also, by 
a short thick fringe made up of black or brown hairs of different 
lengths, each of which ends in a large white seale. This joint, 
although it is enlarged, is twice as long as wide. The metatar¬ 
sus is flattened in front and iridescent blue in color, with two 
long dark spines and a white fringe, which extends on to the 
tarsus, below. In one specimen (from Duncan’s) this first leg 
has many metallic coppery pink scales above, the patella being 
nearly covered with them. This male has a bright red clypeus. 
The second leg has, along the front face, a pure white band with
