 the Orthoptera, however, Mr. J. A. G, Relin tells me that certain

 OrphuIcUa oUvocca, Clinoccphalus clcgans and Chorthippus curiipennis 

 are found along the coast strip but not in the Tine Barreas, while 

 Chloealtis conspcrsa, Paroxya scudderi, Melanoplus imptidicus, and .1/. 

 stonci are restricted to the latter region. 



In West Jersey there are a number of species common to the hilly 

 region to the north and west and unknown in the Pine Barrens, just 

 such a condition as we find among the plants.
