A CONTRIBUTION TO THE KNOWLEDGE OF THE 

 ORTHOPTERA OF MEXICO AND CENTRAL AMERICA. 



BY JAMES A. G. REHN. 



This paper contains the results of a study of 464 specimens, princi- 

 pally from the collection of the author (now presented to the Academy 

 of Natural Sciences of Philadelphia >, beside a small quantity of ma- 

 terial in the collection of the Academy, and an interesting series of 

 118 specimens belonging to the United States National Museum, 

 loaned through the kindness of Mr. W. H. Ashmead of that insti- 

 tution. The specimens from the United States National Museum 

 are designated by the initials of that institution, while those from 

 the author's collection are unmarked. 



The original intention of the author was to make this paper a 

 faunistic study, but many new species and records forced themselves 

 into view, and the conclusion was reached that the present time is 

 too premature for such studies in the region under consideration.
