4 INTRODUCTION. 



In obtaining the materials for compiling the catalogue of the 

 Orthpptera^ which includes species described prior to 1878^ I have 

 been much assisted by Mr. E. W. Janson, of 35, Little Russell 

 Street, Loudon, who copied out for me those descriptions which could 

 not be obtained in the colony. Since writing to him I have found 

 that the following species of Gryllidee has also been described, but I 

 have not been able to include it in this catalogue : Gryllodes maorius. 

 Saussure, Melanges, Fasc. V., p. 377 (1877).
