film analysis by Rovner (1975) revealed the prescence of a 
stridulatory organ at the tibio-tarsal joint. This apparatus consists 
of a file on the distal end of the tibia and a scraper at the base of the 
palpal cymbium. Further examination revealed a group of stout 
spines or macrosetae at the tip of the palpal tarsus. These spines 
apparently aid in coupling the tarsus to the substratum. Thus, the 
sound produced by gulosa ©and other lycosids is not generated 
simply by drumming, but involves a rapid oscillation at the 
tibio-tarsal joint facilitated by macrosetae that anchor the palpus to 
the substratum. 
Kaston (1948) reports seeing mature females of gulosa from Sep- 
tember, through winter, to June suggesting that some may live for 
two years. Egg sacs appear in early April and are produced until late 
May. Egg sacs vary from 6-10 mm in diameter and egg counts range 
from 118-274, each egg about 1 mm in diameter. 
Distribution. From southern Canada in the northeast to eastern 
Texas in the southwest. Not recorded from Florida and a single 
specimen from Colorado (Map 1).
