ForficuJulce ; and the collt'ctions forniod by the collectors 

 attached to scientific expeditions to Christmas Island, the 

 Hawaiian Islands, Socotra, and tin; West Indies (especially 

 St. Vincent and Grenada), and described in the Reports 

 published relative to those expeditions. 



The present volume includes five families of Orthoptera, 

 and it is expected that the remaining three will be completed 

 in one (or at most two) more volumes. 



The pattern adopted for this Catalogue has been that of 

 Mr. Kirby^s unofficial ' Catalogue of Neuroptera Odonata,' 

 published in 1890. 



Special thanks are due to Prof. E. B. Poulton for allowing 

 the types of Blattidw described by Walker from the collection 

 of the late W. W. Saunders, and now in the Hope Museum at 

 Oxford, to be compared with the British Museum Collection, 

 which has made it possible to determine at least the generic 

 position of nearly the whole of "Walker's Blattida). 



Mr. Kirby also wishes to thank Messrs. Bolivar, Bruner, 

 Burr, Caudell, and Rehn for early copies of their papers, some 

 of which might otherwise not have reached him in time to be 

 quoted in this volume.
