 largely of Equisetum, and here most of the Orthoptera were 

 taken.

Sedge marsh habit a\t. Some of the cleared ravines on and 

 in the vicinity of the Warren Woods Preserve have in their 

 moister portions thick growths of sedges, tall grasses, iris, 

 lizard's tail, and cat-tails. The margins of the ponds and 

 small lakes of the inland region are bordered in many cases 

 by a zone of sedges. In the dunes the wet depressions and 

 the margins of the dune ponds are often the sites of sedge 

 growths ; and around the lagoons at Stevensville and New 

 Buffalo there are extensive sedge marshes. The spring-fed 

 marshes and those connected with the larger bodies of water 

 never become dry, but a large number of those which occupy 

 moist depressions or border small ponds dry up completely 

 during the later part of the summer. 



With the exception of the upland thicket and scrub habitat 

 the sedge marsh habitat yielded the largest number of species 

 of any of those studied. The following species were taken 

 here: 



Doru aculeatumf Arphia sulphureaf 



Paratettix cucullatus Chortophaga viridifasciata 



Tettigidea lateralis parvipennis Dissosteira carolinaf 



Tryxalis brevicornis* Schistocerca alutacea alutacea*
