TRANSLATOR'S NOTE 



TTENRI Fabre's essays on Wasps will fill 

 *- * three volumes in all, of which this is the 

 first. The others will be entitled The Mason- 

 Wasps and More Hunting Wasps. The 

 former will include the chapters on the Com- 

 mon or Social Wasp. 



The first seventeen chapters of the present 

 book appeared some years ago, wholly or in 

 part, in a version of Vol. I of the Souvenirs 

 Entomologiques prepared by the author of 

 Mademoiselle Mori for Messrs. Macmillan 

 & Co., by arrangement with whom 1 am now 

 permitted to retranslate and republish them 

 for the purpose of this collected and definite 

 edition of Fabre's entomological works. Of 

 the remainder, The Modern Theory of In- 

 stinct first saw the light in The English Re- 

 view and An Unknown Sense, in an abbrevi- 

 ated form, in The Daily Mail. 



It is a pleasure once more to express my 

 thanks to Miss Frances Rodwell, who, as 

 usual, has rendered me much valuable assist-
