from a dry, sandy upland to the low, marshy areas bordering the salt 

 marshes. The soil throughout is a coarse sand similar to the Norfolk 

 type. In the more elevated areas it may be quite dry at the surface, 

 but is usually underlaid at no great depth by the water-table. The 

 sand is very porous, but its proximity to underground water makes 

 it a good corn and truck soil, as a result of which it has been exten- 

 sively cleared and cultivated. Where the surface of the sand ap- 

 proaches within a foot or so of permanent water-level it is often 

 highly impregnated with organic matter, and in such cases assumes 

 the character of a sandy loam. 



Most of the Coastal Strip is of the open campestral type, though 

 groves and thickets of limited extent are frequent in the shallow 

 depressions leading down to the salt marshes. Where the fields are 

 not cultivated they soon become overrun with native and introduced 

 weeds and bush6s, among which we may mention such forms as the 

 tall bunch-grasses of the genus Andropogon, timothy {Phleum 

 pratense), sand-bur {Cenchrus carolinianus) , Juncus tenuis, species of 

 smart-weed {Polygonum), Scleranthus annuus, bayberry {Myrica 

 caroliniensis, beach plum (Prunus maritima), wild indigo {Baptisia 

 tinctoria), sensitive pea (Cassia nictitans and chamcecrista) , bush- 

 clovers (Lespedeza spp.), 16w evening primrose {CEnothera laciniata),. 

 butterfly-weed {Asclepias tuherosa), blue toad-flax (Linaria canaden- 

 sis), horse-mint {Monarda punctata), low cynthia (Adopogon caro- 

 linianum), rag-weed (Ambrosia artemiifolia) , black-eye susan (Ru- 

 heckia hirta), white boneset (Eupatorium album, etc.), golden aster 

 (Chrysopis mariana), and goldenrods (Solidago and Euthamnia spp.)- 



This vegetation is evidently of a mild xerophytic type. The 



Orthoptera associated with it may therefore be regarded as a xe- 



rophilous faunule of the humicolous subtype and campestral station. 



To this faunule I would refer the following species : 



Syrbula admirabilis Melanoplus atlanis 

 Eritettix carinatus " femur-rubrum 



Orphulella pelidna " femoratus 



Arphia sidphurea Scudderia texensis 

 " xanthoptera " furcata 



Chortophaga viridifasciala Amblycorypha oblongifolia 

 Hippiscus phoenicopterus " uhleri 



" rugosus Microcentrum sp. 



Dissosteira Carolina Concephalus robustus 

 Trimeroiropis maritima " triops 



Psinidia fenestralis Orchelimum vidgare 



Schistocerca americana Xiphidium strictum 



" damnifica " saltans 



Melanoplus scudderi
