INTRODUCTION 



In 1912 the Quebec Society for the Protection of Plants published ''A Pre- 

 liminary List of the Insects of the Province of Quebec, Part I. — Lepidoptera," 

 as a supplement to the Fourth Report. The List was prepared by Mr. Albert 

 F. Winn, of Westmount, now for many years an ardent student and enthusiastic 

 collector of insect life of the Province of Quebec, and was well received by lepi- 

 dopterists of Canada and the United States as filling a long-felt want. 



I am pleased to be able to introduce now the second part of the contemplated 

 work, namely "A Preliminary List of the Insects of the Province of Quebec, Part 

 II. — Diptera," prepared by Mr. Albert F. Winn of Westmount and M. Germain 

 Beaulieu of Ottawa. Thanks to the continued liberality of the Hon. Minister 

 of Agriculture, Mr. J, E. Caron, the List is published as an Appendix to the 

 Seventh Report of the Quebec Society for the Protection of Plants. 



The thanks of the Society are due Messrs. Winn and Beaulieu for their long, 

 tedious and voluntary labours in connection with the compilation of the List, and 

 to Mr. Charles W. Johnson of the Boston Society of Natural History who very 

 kindly revised the M.S. and not only added a number of species to our records 

 but gave much other valuable information and assistance.
