upper sides, which may or may not meet behind, and lower down 
the sides are black. Back of each lateral eye, on the side of the 
head, are two stiff dark curls. The abdomen is red encircled by 
white, and has a central black band which passes forward from 
the spinnerets to the middle of the back, where there is a large 
white spot, in front of which is a pair of smaller white spots. 
The posterior third of the dark central band is metallic and has 
two pairs of white bars on the edges. The clypeus is edged by 
a fringe of long bright red hairs. The falces are dark red, 
slightly iridescent, and are thinly covered with long white hairs 
which form vertical streaks. The femur of the palpus has white 
hairs above and on the inner side. The patella and tibia are 
lighter colored than the tarsus. The legs are reddish with 
darker bands at the ends of the joints. 
The most striking thing about this male is the ornamentation 
of the femur of the first leg, which has, on the under face, with 
the base of the triangle toward the patella, a convex, triangular, 
iridescent blue plate, beyond which, toward the patella, is a soft 
mass of snow-white hairs among which are two black spines. 
Above the plate, on the inner, or front side, is a very downy 
fringe of pale green or white, and outside, or behind the plate 
are white hairs except at the distal corner where there is a long 
dark curl which overhangs the patella. The inner face of the 
femur has a thin black fringe overhanging the white below, and 
on the upper surface of the joint, at the distal end, is a ridge of 
black hairs. The patella, tibia, and metatarsus are fringed with 
very soft white hairs. 
In the female there is a white band over the front eyes, be¬ 
hind this a dark band, beyond which the upper surface is covered 
with red hairs as far back as the beginning of the thoracic slope. 
The sides and lower thoracic part have white hairs thinly cover¬ 
ing the dark integument. There is a dark curl and a smaller 
tuft near each dorsal eye. The abdomen is red without a black 
band, but having the white marks as they appear in the male 
except that the large central spot is broken into two. There is 
a white basal band which runs far back, and an indistinct, whit¬ 
ish, oblique band on each side. Over the abdomen are long
