The characteristic thing about this genus is that the front part 
of the cephalothorax is widely swollen, this peculiarity being as 
marked in the female, as in the male. 
The spiders are large and handsome, the males being darker 
colored than the females, and, usually, having their first legs 
ornamented with fringes of hair. 
The cephalothorax is high and massive, and when looked at 
from in front the sides are seen to bulge out. The ceph¬ 
alic part is inclined. Behind the dorsal eyes is a depression 
and then a slight hump, from which the thorax falls in one 
slope to the margin. The lower outline of the sides is sometimes 
not far from circular, but there is a distinct bulge in the eye- 
region, where the cephalothorax is widest. They round out 
widely from above downward so that although the dorsal eyes 
are on the sides, they form a row which is much narrower than 
the cephalothorax at that place. The quadrangle of the eyes 
is from slightly to plainly wider behind than in front, is from 
one-fourth to two-thirds wider than long, and occupies about 
two-fifths of the cephalothorax. The first row is curved, the 
middle eyes being slightly separated, while the lateral are 
placed further back, with a distinct space between them and 
the middle eyes. The middle eyes are nearly twice as large 
as the lateral. The second row is plainly nearer the first than 
the third. In the male the falces are strong and projecting, 
with a long fang. In the males the first leg is plainly the 
longest, and the fourth next. The falx has one tooth on the 
lower margin. 
This genus has for its type Phidippus cyanidens C. K., which 
we have from Texas, Mexico, Guatemala and Brazil. To this 
we add Phidippus funebris Banks, (Aradhnida from Baja , 
California, and other parts of Mexico ), from Vera Cruz, chrysis 
WTk., and fartilis P.
