Acrosoma spinea (Hentz). (E). 



d" Rockbridge, Ohio, July 1, 1916. 

 cT 9 Columbus, Ohio, July 7, 1914. 

 9 Ohio. (W. H.) 

 On low weeds in open places and in open woods where there is plenty 

 of light. Wideh' distributed, but never very abundant. 



Argiope aurantia Lucas. (E). 



One of the most familiar and striking meadow spiders. Universally 

 distributed. The web is placed low in thick grass or weeds. The 

 nearly mature female feeds very largely on grasshoppers. The males 

 mature in July when both sexes are small and inconspicuous. After 

 mating the female grows to a very large size. 



Argiope trifasciata (Forskal). (E). 



cf Winterset, Ohio, September 17, 1915. 

 cf 9 Columbus, Ohio, August-September. 

 Ohio. (W. H.) 

 This is fully as common and widely spread as the preceeding, but 

 is less conspicuous. It lives in the same situations and matures some- 

 what later. 



Cyclosa conica (Pallas). (E). 



cf Loudon ville, Ohio, June 6, 1915. 



cT Rockbridge, Ohio, May 27, 1916. 

 Taken in hemlock woods. The webs are usually slung between tree 

 trunks five or si.K feet above the ground. 



Cyclosa turbinata McCook. (E). 



c^ Rockbridge, Ohio, July 1, 1916. 

 9 Ohio. (W. H.) 

 This species has been found only below cliffs where it builds its 

 small orb web in weeds in the wettest situations. It seems to prefer 

 i:)laces where a fine mist falls on it or around it. 



Epeira attestor (Petrunkevitch). (E). 



9 Rockbridge, Ohio, July IS, 1916. 



Epeira angulata Clerck. (E). 



This species is closely related to cavatica and is found in similar 

 situations. 



Epeira cavatica (Keyserling). (E). 



cf Sugar Grove, Ohio, July 4, 1915. 

 Rockbridge, Ohio, October, 1913. 

 E. cavatica in Ohio seems to be limited to the faces of overhanging 

 cliffs. Mr. Emerton's comments on these specimens are interesting: 

 "It was first described from Kentucky caves, but here in New England 

 it is a northern species, living in great abundance on piazzas, in wagon 

 sheds, and on barns all over Maine, New Hampshire and Vermont, 

 coming south into northern Massachusetts, but not around Boston or 

 further south. Westward I have it from Spokane. " 

 Epeira domicilorum Hentz. (E). 



9 Columbus, Ohio, September, 1916. 

 Rather common on porches and barns in Columbus.
