In 1865 Bvunner von AVattonwyl publisbcMl his ' Nonvean 

 Systeme des Blattaires,' antl in 18G8 F. Walker, having 

 rearrano-ed the British Museum Coilection, published his 

 ' Catalogne of the Specimens of Blattavi;x! in the British 

 Museum ' (18G8), Supplements to which appeared at intervals 

 from 1869 to 1871. Unfortunately, he was unable to consult 

 Brunner's work while preparino- his own. 



The Mantida: and Pluismhhn are sometinies treated as a 

 separate section of Orthoptera, called Gressoria. 



The Mantldce were rearranged by H. W. Bates, and a, series 

 of plates were prepared to illustrate them ; but these were 

 not published till 1889, when they were issued accompanied 

 by a complete Catalogue of the Family, and descriptions of 

 new species, by J. 0. Westwood, under the title of ' Revisio 

 Insectorum Famili?B Mantidarum.' 



Westwood had previously rearranged the PhasmhJcc in the 

 British Museum ; and in 1859 the Trustees published a 

 monograph on the family, by Westwood, under the title of 

 ' Catalogue of Orthopterous Insects in the Collection of the 

 British Museum : Pnrt I. Phasmida?.' 



In 1893 Brunner von Wattenwyl published a " Revision des 

 Systeme des Orthopteres " in the ' Annali del Museo Civico di 

 Stoi-ia Naturale di Genova,' ser. 2, vol. xiii. The ForficuVuliV 

 and Ilemimeridoi were omitted ; but otherwise the work is the 

 most comprehensive yet published on the Orthoptera as a whole, 

 ) and includes synopses of the families and genera of the greater 

 part of the order, with the exception of the (Tvt/Uida' and some 

 families of the PJiasgonurida\ which had already been mono- 

 o-raphed by Brunner, De Saussure, and others. 



The remaining portion of the present Catalogue will be devoted 

 to the Orthoptera Saltatoria, comprising the families Acliet'nhi' 

 (or Gryllidai), Pliasgoaurida\ und Lociigtidir, or Crickets, (J rass- 

 hoppers, and Locusts. 



These have been previously catalogued by F. Walker in his
