Collecting dates are throughout the warmer season, with peak 

 abundance in July, August, and early September. Unusually early 

 and late dates of capture of special interest are: May 15 at Constance 

 Bay, Ont.; June 13 at Aweme, Man.; June 21 at Norway Bay, Que.; 

 September 11 at Madison, Wis.; September 19 at Ithaca, N. Y.; and 

 October 5 at Plummers Island, Md. 



Six of the female specimens were collected coming to lights at night, 

 at six different localities. One of the specimens is the one reported by 

 Shannon (loc. cit.) as reared from Epeira trivittata. A second reared 

 specimen is a male, hatched on Sept. 11, 1914, by C. R. Ely from a 

 cocoon collected on a spice bush at East River, Conn., on September 2. 



This species is in the Alleghanian, Carolinian, and Lower Austral 

 faunas. Its habitat is rich shady deciduous woods, where it is some- 

 times moderately common late in the summer. Females are some- 

 times attracted to light.
