THE CANADIAN ENTOMOLOGIST 303 



back where they came from so that the collection still stands as 

 it was arranged by Provancher. We did not even feel justified in 

 labeling the specimens which we believed to be the type a^ lecto- 

 types, and will rely in this paper entirely on the name label and 

 the number label for means of correctly identifying the speci- 

 mens which we believe should stand as type. 



* B — Harrington Collection. 



The types in the Harrington collection are in good condition, 

 and although they usually do not bear the name label in Pro- 

 vancher's writing we ,were assured by our friend Mr. W. H. Harring- 

 ton that they were the identical specimens examined by Pro- 

 vancher as could easily be proven by a comparison of the number 

 (they bear in addition to other labels a small, white square on which 

 is written by Harrington a number) with the list as returned by 

 Provancher. 



C — Types in Collection of Canadian Department of Agriculture. 



The. types in the Department of Agriculture are in good con- 

 dition, and have all been properly labeled as types. 



D — Types in U. S. National Museum. 



The types in the United States National Museum have all 

 been accessioned and labeled with Museum type numbers. 



Plan of Paper. 



In submitting this list of the species described by Provancher 

 and presenting notes on the location and condition of the types 

 we have considered that it was much better to arrange them 

 alphabetically as they appear in the final index published by Pro- 

 vancher as a conclusion to his two more important papers on 

 Hymenoptera. We have chosen this method largely because there 

 will be many more changes in generic position than those already 

 published, and also because we do not know when we shall have 

 an opportunity to completely review our notes and definitely 

 assign the species of the genera as at present understood. Prac- 

 tically throughout this paper the word "type" is used in the sense 

 of "lectotype." There are, however, certain cases when there 

 was only one specimen, and there is no doubt that it is the speci- 

 men examined by Provancher and is, therefore, certainly the type.
