"The ash-gray harvest-spider passes the winter in the egg state. A 

 few years ago in Illinois I found a bunch of about a dozen small, white, 

 spherical eggs slightly beneath the soil surface, Avhich were transferred 

 to breeding cages. During the spring they hatched into small gray 

 Phalangiids, which were believed to belong to the present species. I 

 have never seen the female engaged in ovii)osition, but the structure 

 of the ovipositor indicates that the eggs are deposited in the ground 

 about half an inch below the surface. In the latitude of central Ohio 

 there are apparently two broods each season, the first maturing late in 

 June or early in July, and the second, which is much more numerous 

 in individuals, in September. 



"This species is preeminently what may be called an in-door form. 

 It abounds especially in sheds, outhouses, and neglected board i>iles, 

 being rarely found in the open field. Its color especially fits it for 

 crawling over weather-beaten boards, making it inconsi)icuous against 

 such a background. During the day it is usually quiet, but at dusk 

 and on cloudy days it moves about quite rapidly. It probably feeds 

 upon small flies and other insects that it finds during its nocturnal 

 rambles. The only natural enemies I have seen it suffering from are 

 the web-making spiders, in the webs of which it often perishes by get- 

 ting its long legs iuextricably entangled."* 



Individuals of this species seem to be very irregular in becoming 

 fully developed, and it is difticult to determine whether there is more 

 than one generation a year or not.
