The above lists are doubtless individually incomplete. On the 

 whole, collections made in the Appalachian District are essentially 

 Piedmont in character with the addition of some prevailingly northern 

 species which are absent or rare in the Piedmont. It is probable at 

 least from the data at hand that the following species occur regularly 

 throughout the entire local Appalachian District: Orphulella 

 speciosa, Chloealtis conspersa, Stenohothrus curtipennis, Arphia 

 sulphurea, A. xanthoptera, Chortophaga viridifasciata, Encoptolophus 

 sordidus, Hippiscus tuberculatus, Dissosteira Carolina, Spharagemon 

 bolli, S. saxatile, Melanoplus fasciatus, M. atlanis, M. fernur-nibrum, 

 M. minor, M. femoratus, Scudderia curvicauda, S. furcata, Amhly- 

 corypha oblongifolia, A. rotundifolia, Conocephalus triops, C. ensiger, 

 Orchelimum vulgare, Xiphidium fasciatum, X. hrevipenne, X. nemorale, 

 and Atlanticus dorsalis. 



The following have so far been recorded only for the more northern 

 section of the local Appalachian District, to which it is possible that 

 they may be restricted: Mecostethus lineatus, Camnula pellucida, 

 Circotettix verruculatus, Podisma glacialis variegata, Melanoplus 

 mancus,^ M. pundidatus, and Scudderia pistillata.^ 



It is rather surprising that we have no local records of Melanoplus 

 luridus in the Appalachian District, this being a form which is 

 prevailingly northern in distribution and which has been recorded 

 from the mountains of Virginia, North Carolina, and Georgia. 



Another species, Xiphidium saltans, probably occurs in the dis- 

 trict, but I know of no actual records of its capture. 



The most distinctive Orthoptera of the Appalachian District are 

 Camnula pellucida, Spharagemon saxatile, Trimerotropis citrina 

 Circotettix verruculatus, Podisma variegata, Melanoplus mancus 

 (probably), and Xiphidium nemorale. These species are either 

 confined to the district or recur only in the Highlands. 



The majority of Appalachian Orthoptera are Piedmont types. 

 These include Orphulella speciosa, Dichromorpha viridis,^ Chloealtis 

 conspersa, Stenohothrus curtipennis, Arphia sulphurea, A. xanthoptera, 

 Chortophaga viridifasciata, Encoptolophus sordidus, Hippiscus tuber- 

 culatus, Dissosteira Carolina, Spharagemon bolli, Melanoplus atlanis, 

 M. femur-rubrum, M. minor, M. femoratus, Scudderia texensis, S. 



6 Recorded from the Highlands of New Jersey, but doubtless occur in the 

 Appalachians. 



' I am not sure whether this species ought to be ranked as an Appalachian 

 species or not. It is abundant in the Piedmont and has been taken along the 

 edge of the Appalachian, but I know of no records from typical Appalachian 

 country.
