TRANSLATOR'S NOTE 



This is the second volume on Wasps in the 

 Collected Edition of Fabre's Souvenirs en-

 Hunting Wasps; and the present volume is 

 somewhat wilfully entitled, for all Wasps

 essays treating of those Wasps wjho. actually 

 build homes or nests, as distinct from bur- 

 rows. The last book on Wasps will be 

 called More Hunting Wasps and will be is- 

 sued towards the end of the series. 



For reasons which will be easily apparent 

 to the reader, I have reprinted the chapter 

 called Instinct and Discernment, which was 

 included in Bramble-bees and Others, and 

 that on the Volucella, which, under the title 

 of The Bumble-bee Fly, formed part of The 

 Life of the Fly. Apart from the two chap-

 which figures in The Wonders, of Instinct, 

 published in America by the Century Co.,
