first is heavily fringed with black excepting on the patella and 
the proximal ends of the terminal joints, where the hairs are 
white. The tibia has a thick brush from end to end. The pal¬ 
pus is black, without a white band. In the female the femora 
are all dark, while the other joints are dark at the distal and 
light at the proximal ends, the third and fourth being lighter, 
as a whole, than the others. The clypeus is red edged with 
white, and the f alces are iridescent blue. 
Hentz says that cardinalis is from the southern states. We 
have it from Wallace and Stockton, Kansas; Denver, Colorado; 
Texas; and Claremont, California. Mr. Banks reports it from 
Biscayne Bay, Punt a Gorda and Enterprise, Florida. 
We have some red males and a female from Oklahoma which 
differ from cardinalis only in the epigynum and palpus; the 
form of these parts obliges us to class them as ardens.

In the male the upper surface of the cephalothorax is red 
except for a black hairless region extending from the first to the 
second row of eyes, on the cephalic plate. This region is scal¬ 
loped behind. The hairs on the sides and on the lower thor¬ 
acic part tend to become yellowish or white. The abdomen is 
red with a more or less distinct white band on the base and sides, 
which sometimes nearly encircles the dorsum. Above, it is us¬ 
ually uniform red, but sometimes shows two pairs of white bars 
on the posterior part. The palpus is of a light reddish color 
and is covered, above, with white scales and hairs, which grow 
long on the tarsus. These are quite different in appearance from
