ORTHOPTERA OF NORTHEASTERN AMERICA. 



sions to which they pertain. In most instances, to avoid repeti- 

 tion and save space, these characters are not re-mentioned in the 

 descriptions which follow, and the keys should therefore ahc-ays 

 be used in connection iritJi the descriptions. Moreover, it should 

 be remembered that the characters used and statements made both 

 in keys and descriptions are to be considered as applying- only to 

 those species occurring in the territory covered by this work. 

 They may be, and in general are, capable of much wider applica- 

 tion but it is not safe to assume that such is the case. 



Following the description of each species are notes on its dis- 

 tribution, food habits, song, etc. The general range or area of 

 distribution given is based not only on my personal collecting in 

 Indiana and Florida, but also on the specimens which have been 

 examined in other cabinets and on the published local lists and 

 other works cited in the Bibliography as well as manuscript lists 

 furnished by several persons. The synonymy of many species is, 

 however, so involved that the range as given, especially where it 

 extends beyond our territory, is to be considered as open to cor- 

 rection. The dates of occurrence as given are usually the earliest 

 and latest at which the species has been noted in the locality cited 

 and do not therefore necessarily show the actual time of its ap- 

 pearance or disappearance. 



Of the 353 species and 58 varieties of Orthoptera recognized or 

 recorded as inhabiting the territory covered I have been able to 

 examine personally the types, or undoubted correctly identified 

 paratypes, of all but five. 1 The great majority of the spe- 

 cies treated are represented in my own collection. The source of 

 the specimens at hand as I wrote the descriptions is usually given 

 in the notes following each description. Thus "Lakehnrst, N. 

 Jer. (Davis)" means that the specimens at hand were taken at 

 Lakehurst and loaned or presented to me by W. T. Davis ; while 

 "Ormond and Dunedin, Fla. (W. X. /?.)'' signifies that the speci- 

 mens examined were taken by myself at the localities mentioned. 

 After preparing the greater part of the text I visited Cambridge 

 and Wellesley, Mass., Staten Island, N. Y. and Philadelphia, Pa., 

 to examine the species not previously seen and to study the types 

 and other specimens in the Scudder, Morse, Davis and Philadel- 

 phia collections. These contain the great majority of all the types 

 of the United States species. Other cotypes or paratypes from 



'These are Pltvllo'i'atcs chlo;'oph(ca Blanch., a mantid of doubtful occurrence in the 

 Southern States; Hcteroncmia Icrvissiinus, and H. te.i'aiius Brunner, two phasmids of 

 doubtful status; Bcloccplialus c.\'c wains Davis, the unique type of which is in the Amer- 

 ican Museum of Natural History, which Institution I did not find opportunity to 

 visit, and Ceuthophilus scabripcs (Hald.). a camel cricket, the type of which is lost and the 

 status therefore doubtful.
