DiPTERA. 



(Arranged according to a catalogue of North American Diptera, by J. M. 

 Aldrich, Smithsonian Misc. Coll. XLVI, No. 1, 444. The numbers refer to the 

 pages in the catalogue.) 



Large collections of these insects have been made in certain of the provinces 

 during 1915. The appearance of Winn and Beaulieu's list of Quebec diptera will 

 doubtless encourage collectors in that province to add to the list. Recently we 

 had the pleasure, at Ottawa, of a visit from Prof. J. M. Aldrich, who came to 

 study the collection of diptera in the collection of the Entomological Branch. 

 Many species were determined by him, and the records of a number of these are 

 undoubtedly new to Canada.

 ones, I am informed by Mr. Harper, and should be corrected to read,
