Peckham—Revision of the Attidce of North America . 435 
white spots in front, a large white triangle, and two pairs of 
white bars near the end. There is a wide white basal band, 
continuous with the middle part of which a white band (some¬ 
times not very distinct) passes back on either side of the dark 
central region to near the end of the abdomen. In one speci¬ 
men the inner edges of these white bands are delicately edged 
with red. Beyond these bands the sides of the abdomen are 
brown, covered with gray hairs, and marked, low down, by two 
oblique white bars, edged with black. The venter has a wide 
dark central region which is rounded at the spinnerets and wid¬ 
ened a little near the epigynum. 
The falces are bronze green. The palpi are yellowish, with 
white hairs. The first, second and third legs, excepting the 
metatarsi and tarsi, are rufus, the metatarsi being yellow except 
the distal third, which is rufus, and the tarsi being all yellow, 
excepting those of the first pair, which have a dark ring in the 
middle. The fourth leg has the femur and patella rufus, the 
tibia and metatarsus with the proximal half light colored, and 
the distal half dark brown, and the tarsus entirely light colored. 
All the legs are thinly covered with short white hairs. 
We have one female from Arizona and one in the Marx col¬ 
lection, marked North America. 
Workmanii is much like famous in abdominal marking, but 
the cephalothorax is banded and the epigynes are of different 
types.
