第1章 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 entitled "The Hunting Wasps" and the "Mason-wasps" respectively.

Chapter 2 has appeared before in my version of "The Life and Love of the Insect," an illustrated volume of extracts translated by myself and published by Messrs. Adam and Charles Black (in America by the Macmillan Co.), and Chapter 10 in a similar miscellany translated by Mr. Bernard Miall published by Messrs. T. Fisher Unwin 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 translation.
