part of the body. It is highly probable that the vibrations set up 
in the substratum by the tapping movements of the palps and 
abdomen are perceived by the female. This may exert an excit- 
ing influence on her in a manner analogous to that which 
occurs in web-building species, where the male tweaks the 
threads of the female’s snare. 
The male now moves slowly toward the female without 
courting. When near her he reaches over to touch her. At first 
she may jump at him and chase him away. Later, if she is 
receptive she allows him to stroke her legs or abdomen. After 
this contact with the female the male resumes his courtship

quickly. During this process the legs quiver violently. 
After 13 minutes of this courting one male began to mount 
the female, but before he could get into the final copulatory 
position, she ran away from him. Another male had courted 
only seven minutes when the female allowed him to mount. The 
position is the usual one for Lycosids, the male using his palps
