 The sternum is black. The legs are marked with broken dark 

 rings. 



The epigynum is narrow in front with two small openings ; it is 

 widened in the middle and has a small T-shaped end behind,

 The burrows of this species do not usually have a tube of straw 

 or other rubbish around the mouth. The edge of the tube is thickly 

 covered with silk, which extends out sometimes an inch around it 

 on the surface of the sand. In digging, the surface of the sand is 

 first covered thinly with silk. A ball of sand held together by the 

 silk is then gathered up and carried to the mouth of the burrow 

 in the mandibles; there, without the spider coming out of the hole, 

 it is placed on the ends of the front legs, and thrown as far away 

 as possible. In full grown spiders this is about two inches, and 

 the balls of sand may sometimes be seen in a circle of this radius 

 around the hole. When looking for prey, the spider sits with the 

 cephalothorax and front of the abdomen out of the hole and the 

 feet turned under the body as if dead. A step on the sand within 

 ten feet will alarm them and they disappear down the burrow, but 

 by creeping slowly without jarring the ground or throwing a shadow 

 over the hole, one may get within two feet of the spider without 

 disturbing it. The spider will notice an insect moving six or eight 

 inches away and will rush out and catch one at that distance, 

 returning quickly with it to the burrow. The adult males live part 

 of the time in holes like females, and lie out at the top and wait 

 for insects in the same way, but in August and September they 

 are often found wandering. A male confined over night and then 

 turned loose near the burrow of a female at once looked into it, 

 reaching down its whole body except the tip of the abdomen and 

 the fourth legs. It quickly came out, followed to the mouth of the 

 burrow by the female who at once went down again, and returning 

 in a few seconds, seated herself in the usual position over the edge 

 <il the hole. The male then approached slowly with the front of
