THE ATTID^ 



65 



of an inch long and very slender. The cephalothorax is 

 narrowed behind and the abdomen in front, and each has a 

 deep depression in the middle. The stem of the abdomen is 

 flat, and widened behind so that it is nearly as wide as the ends 

 of the thorax and abdomen, which it connects. The 

 front middle eyes are large and cover two-thirds of 

 the width of the front of the head, and the rest of the 

 eyes are small. The legs are all slender, the hind 

 pair longest. The general color is black, with yellow- 

 ish or orange-white markings. There is a triangular 

 white spot in front of the dorsal groove, and one on 

 each side widening downward under the posterior 

 eyes. On the abdomen there is a white stripe 

 extending downward from the dorsal depression on 

 each side and uniting in a large white patch under- 

 neath (fig. 164). In pale individuals the whole front 

 half of the abdomen is light yellow or orange brown. 

 The second legs are entirely white, the others partly 

 black. The male has the head higher and is darker colored 

 and more slender. 



This spider not only resembles an ant in form and color but 

 moves like an ant. It does not jump like most Attidae, though 

 it can do so, but walks and runs irregularly about and lifts its 

 first legs high like the antennae of ants. 



Lyssomanes viridis. — A bright green spider common in the 

 southern states. The arrangement of the eyes differs from 

 that usual in the Attidae by the front lateral eyes being higher 

 and closer together, so that they are over and behind the front 

 middle pair (fig. 165). The cephalothorax is narrow in front, — 

 not much more than half as wide as it is across the middle. 

 The abdomen is narrower than the thorax and more than twice 

 as long as wide. The female is a third of an inch in length, 

 and the male quarter of an inch. The legs are long and slender,
