to perfect it by every means in my power, and to examine all possible 
aids. Accordingly the indexes to the Geological Record, the Zoological 
Record, and the Zoologischer Jahresberichtf 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 uature have also been carefully examiued. 
A list of such works as have been systematically studied for this purpose 
is here appended.
