stripe as wide as the eye-area. The edges of the thorax are also 

 light. Between these the sides of the ceplialothorax are dark brown, 

 almost black near the edges of the middle stripe. 



The abdomen is light gray in the middle. At the sides in front 

 are two dark spots, darkest in front, extending back half the length 

 of the abdomen and between them are two small dark spots near the 

 muscular spots on the first segment. The hinder half of the abdo- 

 men is marked by scolloped transverse dark lines. The legs are cov- 

 ered with gray hairs and scattered dark spines. 



The sternum is dark brown and the coxai nearly as dark. In the 

 middle of the under side of the abdomen is a black marking more 

 than half as wide as the body extending from the spiracles to the. 

 spinnerets. The front part of the abdomen is brown like the coxre. 

 The mandibles are dark brown with a few light hairs on the front 

 near the base. The palpi are a little longer than the first femur and 

 light gray, except the tarsus which is a little darker. The palpal 

 organ is moderately large, the tube and its support much longer than 

 in carolinensis, but proportionally shorter tlian in pratensis, etc.

The colors and markings are very variable in this species. The 

 most distinctly marked individuals are very dark browm or black 

 with light gray and yellow markings and dark rings on the legs. 

 The lighter specimens have the legs light gray and all the darker 

 parts of the body of the same color. In the dark variety the cepha- 

 lothorax is dark brown with a narrow light gray stripe in the middle 

 and on each side. The middle strij)e divides into three in front, the 

 middle part extending forward between the eyes to the front of the 

 head, while the side branches end in front of the hinder eyes. The 

 abdomen is dark brown with two bright yellow stripes on the front 

 part that unite into one behind the middle and are indistinctly divi- 

 ded into segments by grayish lines. Along the sides of the yellow 

 lines are several pairs of irregular black spots. The legs are ringed 

 with gray and dark brown. IMie under side of the abdomen is gi'ay, 

 with a black stripe each side, which unite in front of the spinnerets 

 and sometimes are connected in front by a black transverse line be-
