Phidippus insignarius, Koch. 1846. (Plate XI, fig. 2 and 2d.) 
The male is described by Peckham as the male of Phidippus coma- 
tus in Trans. Wisconsin Acad., April, 1901. 
Male 8 mm. long; cephalothorax black with two wide white 
stripes beginning below the lateral eyes in front, and turning upward 
behind, where they nearly meet under the front of the abdomen. 
There are two pairs of tufts of long black hairs at the sides of 
the head. The abdomen is orange red with black and white mark- 
ings; there is a white stripe around the front, and a scolloped 
black middle band including a middle orange spot, and two smaller 
orange spots in front of it. The ornamentation of the face and 
front legs is striking and complicated. The lateral white stripes 
extend around under the front eyes as far as the middle pair, but 
do not meet under them, and below these are long white hairs 
that cross each other and nearly cover the mandibles, so that their 
iridescent. blue color is concealed. The palpi are white, with a 
little mixture of brown. The first legs are covered on the under 
side with long white hairs; the hairs of the cox point downward, 
nearly to the ground; the femur has a row of stiff white hairs as 
long as its diameter along the outer side, and the other joints 
have hairs extending more than their diameter each side to the 
ends of the tarsi. When the first legs are pointed upward, the 
whole front appears white except the upper part of the head, 
which is black, extending outward at the sides in four black tufts. 
When the first legs are down in walking position, the upper side 
becomes visible in front, and this is covered with black hairs at 
the sides and, as far back as the patella, with a middle stripe of 
orange. The second leg is striped in the same way, but not as 
brightly, and has shorter white hairs. 
The female is a little larger than the male, and marked on the 
back less distinctly in the same way. The cephalothorax is brown 
with lateral white stripes and tufts of long hairs on the head as 
in the male. The abdomen is light and dark brown with gray 
hairs; there is a white stripe around the front end and a square 
white spot in the middle. The dark middle band is broken into 
two pairs of black spots in the front half. The epigynum has a 
small notch in the hinder edge and two anterior openings close 
together separated only by a narrow ridge. 
Dendryphantes Jeffersoni, new. (Plate XI, figures 3 and 3e.) 
Males 4 mm. long. Color brown: mixed with white and yellow.
