X PREFACE. 



to perfect it by every means iu iny power, and to examine all possible 

 aids. Accordingly the indexes to the Geological Record, the Zoological 

 Eecord, and the Zoologischer Jahresberichtt of the latest dates before 

 1880 have been entered with the others, and an extensive series of 

 memoranda of genera of lepidoptera, orthoptera, and fossil insects in 

 my possession have been carefully examined. A number of books af- 

 fording memoranda of this nature have also been carefully examined. 

 A list of such works as have been systematically studied for this purpose 

 is here appended.
