TRANSLATOR'S NOTE 



The fourteen chapters contained in this 

 volume complete the list of essays in the 

 Souvenirs entomologiques devoted to Wasps. 

 The remainder will be found in the two 

 earlier volumes of this collected edition en- 

 titled The Hunting Wasps and The Mason- 

 wasps respectively. 



Chapter 11. has appeared before, in my 

 version of The Life and Love of the In- 

 sect, an illustrated volume of extracts trans- 

 lated by myself and published by Messrs. 

 Adam and Charles Black (in America by the 

 Macmillan Co.), and Chapter X. in a sim- 

 ilar miscellany translated by Mr. Bernard 

 Miall, published by Messrs. T. Fisher Un- 

 win Ltd. (in America by the Century Co.) 

 under the title of Social Life in the Insect 

 World. These two chapters are included 

 in the present book by arrangement with the 

 original firms. 



I wish to place on record my thanks to 

 'Mr. Miall for the valuable assistance which 

 he has given me in preparing this transla- 

 tion.
