In addition to the sand}^ pine lands and the peat bogs, which 

 represent the two native Pine Barren types of environment, there 

 is a minor third type consequent upon the operations of man. Where 

 the country is cleared and settled and the land placed under cultiva- 

 tion, conditions are produced which favor a fauna and flora essentially 

 like that prevailing in the Delaware Valley and Coastal districts. 

 In such places a weedy type of vegetation predominates, characterized 

 by forms common in the low-lying sandy areas of those districts, 

 among which we may mention the following: Syntherisma san- 

 guinalis, Phleum pratense, Chcetochloa viridis, Cenchrus carolinianus, 

 Sisyynhrium officinale, Draba verna, Trifolium arvense, T. pratense, 

 T. procimibens, Melilotus officinalis. Cassia nictitans, Strophostyles 

 helvola, Asclepias tuherosa, Monarda punctata, Verbascum thapsus, 

 Linaria canadensis, Plantago lanceolata, Specular ia perfoliata, 

 Ambrosia arlemisii folia. 



There are thus three types of habitat characteristic of the Pine 

 Barrens, i.e., (1) the sand barrens; (2) the peat bogs; (3) the cul- 

 tivated areas. Each of these is distinguished by certain peculiarities 

 of flora and fauna. 



The entire grasshopper fauna of the Pine Barrens (exclusive of 

 the groups not considered in this paper) includes, to my knowledge, 

 the following species. Some of these are referred to this fauna with 

 a query, owing to the fact that all records of their capture are close 

 to the borders of the Pine Barrens, a fact indicative of the possibility 

 of their being merely stragglers from the adjoining districts.
