examined by Provancher 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 Harring- 
ton a number) with the list as returned by Provancher.

PLAN OF PAPER. 
In submitting this list of the species described by Provan- 
cher 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 Provancher 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 be- 
cause we do not know when we shall have an opportunity to 
completely review our notes and definitelv assign the spe- 
cies of the genera as at present understood. Practically 
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 specimen examined by Provancher and 1s, therefore, 
certainly the type.
