viii PREFACE. 
Bates, Dr. GiinTHEeR, Mr. Kirpy, and Mr. WATERHOUSE, 
for their kind assistance in the preparation of the 
plates. 
As regards bees and wasps, I have confined myself 
for want of space to the simple record of my own 
observations. 
I am fully conscious that experiments conducted 
as mine have been leave much to be desired, and 
are scarcely fair upon the ants. In their native 
haunts and under natural conditions, more especially 
in warmer climates, they may well be expected not 
only to manifest a more vivid life, but to develop 
higher powers. 
I think, however, that my volume will at least show 
the great interest of the subject, and the numerous 
problems which still remain to be solved.
