is yellowish, and has a black stripe on each upper side, the meta¬ 
tarsus and proximal half of tarsus yellowish, and the end of 
the tarsus jet black. The palpus has, on the tarsus, a long 
bunch of soft, raspberry red hairs. The tibial apophysis is 
single, with one point. In a form from Victoria, the crest over 
the eyes is brown, the falces are black, the clypeus dark but iri¬ 
descent, and not only has the first leg red hairs through the 
length of the femur but the fringe of red on the first leg is re¬ 
peated on the second, and all the legs are banded, longitudinally, 
with black and white. The tibial apophysis is double, with 
two points. In a third form, which we found at Sisson, the 
crest is brown, the falces are iridescent white with three dark 
vertical lines on each, the clypeus is iridescent white, the tibial 
apophysis is double, and there is no red on the legs, the femur 
having only a brush of black, below, at distal end. The palpus, 
in the Victoria and Sisson specimens, has bright red hairs on the 
tarsus, and has the tibia with white hairs. In a male which 
Mr. Emerton found 8,000 feet up on Mt. Shasta, the tibia is 
pink, and the tarsal plume pinkish yellow. 
In this specimen and in the one from Sisson, the legs are 
black, the first one with a white line throughout its length above, 
and separate diagonal white bars on the inner faces of femur 
patella and tibia. The patella is edged by a white band, ex¬ 
cept at the proximal end. The second leg is marked in the 
same way, but less distinctly. 
In all of our specimens the cephalothorax is black, with a low 
encircling band of white. The abdomen is black, with a cen¬ 
tral white band which narrows a little from base to apex. The 
lower sides are white, cut by two slender diagonal black lines. 
The venter is white. 
Mr. Hanham has sent us several females, but only one of them 
is mature. This has less black than the male, and the white is 
replaced by a bright reddish fawn color. The cephalothorax is 
nearly all fawn, with erect black hairs on the eye-region and 
black bands under the side eyes. The clypeus has white hairs. 
The abdomen has a black ground on which are basal and middle 
indistinct transverse bands of fawn and a herring-bone stripe
