spot extending from the lung openings back nearly to the spinnerets. 
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 male palpus is much like that of ZL. mdicola fig. 1e, which 
is from a specimen from Providence, R. I. belonging to Mr. Banks.

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