studies in malayan, melanesian and australian 

 tettigoniidae (orthoptera). 



By Morgan Hebard. 



In 1920 the author published a first paper, dealing with that 

 part of the collections here treated which covered the section be- 

 longing to the family Mantidae. 1 



Though the present paper is considerably larger, the number 01 

 species of Tettigoniidae known from the regions under consideration 

 is very much greater and, as a result, the present work is not 

 intended to be in any way monographic. A number of difficulties 

 have been cleared up and the proper sequence of species in some 

 places we feel is now defined. 



Much work remains to be done, and the Tettigoniidae of these 

 regions must be monographed before the student will be able to 

 determine material in small series. The literature on the group 

 is too vast and scattered to be accessible, unless a great amount of 

 preliminary work has been done; and reference to a large and 

 comprehensive library is a constant necessity. In order to aid in 

 locating the literature, particularly that subsequent to Kirby's 

 Catalogue, numerous references have been given in the present 

 study. 



All of the material here recorded, unless otherwise stated, is in 

 the author's collection at The Academy or Natural Sciences of 

 Philadelphia, with the exception of duplicate specimens from 

 Mr. C. F. Baker, representing species not in his collection; such 

 will be forwarded to him whenever desired. Five hundred and 

 thirty-one specimens are recorded, representing ninety-four genera 

 and one hundred and ninety-one species, of which fourteen genera, 

 one subgenus, seventy-three species, and one subspecies, are new. 

 Unfortunately, the great majority of species are represented by 

 but one or two specimens. 



We have found that Wallace's line separates quite as large a 

 percentage of species of Tettigoniidae as of the Mantidae, clearly 

 delimiting the Malayan from the Melanesian fauna.
