Peckham—Revision of the Attidce of North America. 371 
The cephalothorax is brown, darkest above the front eyes, 
with the side eyes on black spots. Under alcohol the front third 
of the abdomen is brown with two light lines, sometimes con¬ 
nected by longitudinal bars; there is a light ring around the 
constriction, and back of this the color is dark. A variety from 
Arizona, of which we have a single male, has the abdomen black 
with a round pure white spot on each side, in the constriction. 
The legs are yellow, with dark longitudinal lines (more or less 
broken) in front and behind, excepting the first pair in the 
male, which has the femur, patella and tibia enlarged and dark¬ 
ened. The black-abdomened variety has the first leg of a uni¬ 
form reddish-brown color, except that the metatarsus is darker 
on the outside and lighter within, and the tarsus light; the second 
leg is dark with a pale tarsus; the third is light with a dark 
longitudinal line in front; the fourth is brown with a pale tarsus 
and two dark longitudinal lines. Urom below, the coxae and 
trochanters of the first pair are reddish, the second and third 
coxae and all the other trochanters are white, and the fourth 
coxae are black. 
Mr. Emerton has this species from Cambridge, Mass., Eliza¬ 
beth City, N. C., and Charleston, S’. C.; Mr. Banks, from Long 
Island, N. Y., Louisiana and Arizona, and Hentz had it from 
North Carolina and Alabama. In our collection are examples 
from New York, Ohio, Arizona, Texas and California.
