and the second, wliicli is niucli nioiv numerous in individuals, in 

 September. 



*' This species is pre-eminently what may be called an in-door 

 form. It abounds especially in sheds, out-houses and neglected 

 board piles, being rarely found in the open field. Its color especially 

 fits it for crawling over weather-beaten boards, making it incon- 

 spicuous against such a backgrountl. 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 du- 

 ring 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 getting its long legs inextricably entangled."
