EDITOR'S PREFACE TO THE NEW EDITION. 



THE proprietors of this interesting work having felt that, 

 much additional knowledge of the subject has been obtained 

 since the book was written, have asked me to supply charac- 

 teristic examples of Insect Architecture which were not to 

 be found in its pages. I have accordingly added a con- 

 siderable number of such examples, in most cases accom- 

 panied by figures drawn from the specimens described. I 

 have not been at liberty to alter or expunge, and am not, 

 therefore, responsible for any portion of the letterpress 

 except those passages which are enclosed in brackets [ ]. 

 Some of the specimens from which the figures have been 

 drawn are in my own collection, but the greater part are to 

 be found in the British Museum.
