NOTES ON THE ORTHOPTERA OF COSTA RICA, WITH DESCRIPTIONS 

 OF NEW SPECIES. 



BY JAMES A. G. REHN, 



The following notes and descriptions are based on a study of over 

 three hundred and fifty specimens, representing one hundred species, 

 of which eleven are here described as new. This material is distributed 

 through the collections of the Academy of Natural Sciences of Phila- 

 delphia, the United States National Museum and the private collection 

 of Mr. Morgan Hebard, of Chestnut Hill, Philadelphia. 



The writer is much indebted to Prof. P. Biolley, of San Jose, Costa 

 Rica, who courteously supplied some very valuable material accom- 

 panied by full notes and remarks, and also to Dr. William H. Ashmead, 

 of the United States National Museum, and Mr. Hebard for permission 

 to study the collections mentioned above. 



The number of records here ])ublished which extend the range of 

 species is rather remarkable, and clearly shows the lack of definite 

 information regarding the Orthoptera of northern South America. 



The Forficulidae, Blattidse, Mantidse, Phasmidse and Acrididse of the 

 greater portion of these collections have already been studied and 

 reported by the author.^
