This spider is about 6"'"' long. The color is white and gray, vary- 

 ing from almost white to almost black. The abdomen of tlie female 

 has a prominent hump at the hinder end varying in size in diiFerent 

 individuals. In the male there is only a slight trace of the hump. 

 The cephalothorax is longer than wide and highest behind the middle. 

 The color of the cephalothorax is dark gray or black with some- 

 times a light area just behind the eyes. The legs are white with 

 dark rings at the end of each joint and in the middle of each joint 

 except the femora on which there is only a mark on the under side. 

 On the first and second femora the dark ring is very wide, covering 

 sometimes more than half the joint. In light individuals the mark- 

 ings on the abdomen are obscure, but in well marked specimens 

 there is a dark foliujn widest near the base of the hump and broken 

 in two places at the sides. The sides of the abdomen and the back 

 part between the hump and the spinnerets are marked with irregular 

 black and white ov yellow lines. The under side is black with a pair 

 of very distinct light spots across the middle. The sternum is dark. 



The male is smaller than the female, has a smaller hump and a 

 wider and darker thorax. The palpi are large. The tarsus is small 

 and pointed at the end and does not cover the large palpal organ. 

 The tube is long and hair-like, supported at the end by a stout hooked 

 process. Fig. 11. The epigynum is nearly all external. It is widest 

 at the outer end and has a small finger.

This species seems to live all the time in the web. Across the 

 web there is usually a line of dead insects and other rubbish fast- 

 ened together with a quantity of loose web in which the cocoons are 

 also concealed. The spider standing in the middle of this band 

 where it crosses the center of the web looks like part of the rubbish.
