constituent of the flora, though not uncommon in spots throughout 

 the whole lower part of the peninsula. 



Orthoptera, such as we are concerned with in this article, occur 

 in numbers only in those parts of the Interior District where more or 

 less extensive clearings exist in the otherwise continuous forests. 

 Where the clearings are small and entirely surrounded or bordered 

 by the woods, a sylvan type of fauna obtains similar in facies to that 

 of the Pine Barrens, but lacking some of the more distinctive species 

 of the latter,, such as Spharagemon wyomingianum, Melanoplus 

 fasciatus and impudicus and Orchelimuyn erythrocephalum. This 

 faunule is best developed in the northern section of the district; 

 in the southern section it appears to be only locally represented. 



The species usually associated with the dry pine and oak woods 

 are the following: 



Orphulella pelidna Schistocerca rubiginosa 



Arphia sulphur ea Melanoplus scudderi 

 Hippiscus phoenicopterus " luridus 



Spharagemon bolli Scudderia curvicauda 

 Psinidia jenestralis " furcata 



Scirtetica marmorata Amblycorypha oblongifolia 



Schistocerca damnifica Microcentrum sp. 



The bogs are characterized by the presence of the following: 



Schistocerca alutacea Scudderia furcata 



Scudderia curvicauda 



In the extreme southern portion of the peninsula some of the 

 species here listed are apparently only locally represented. This 

 is especially the case with the more characteristic Pine Barren forms, 

 such as Scirtetica marmorata, Melanoplus luridus and Schistocerca 

 alutacea and rubiginosa, all of which are abundant in the northern 

 section, but are of only exceptional occurrence in the southern 

 section. Their scarcity is evidently correlated with the absence of 

 typical Pine Barren conditions. 



In the Interior District removal of the forest on any extensive 

 scale and the utilization of the land for agricultural purposes is 

 followed by changes in the character of the fauna and flora similar 

 to those taking place under like conditions in the Pine Barrens. 

 The more exclusively sylvan species disappear and their place is taken 

 by campestral types like those of the neighboring Coastal District. 

 I have given especial attention to this matter in the vicinity of South 

 Seaville, where the country adjoining the road connecting the seaside 

 with the baysidejhas been largely cleared and placed under cultiva-
