Phidippus insignarius, Koch. 184(5. (Plate XI, fig. 2 and 2 d.) 

 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 while 

 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 coxa; 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 3 e.)
