Two lists of Canadian Lepidoptera have been published by our Entomological Society; the first one, prepared by Mr. W. Saunders and issued in 1864, contained the names of all the Butterflies, Sphinges, and Bombyces then known to inhabit this country; the next year a second list, prepared by ourselves, was issued, containing the names of species in the remaining families of moths, and some additions to the former list. Since then a number of new species have been captured in this country, whose names may now be added to our lists; great changes have also been made in the generic nomenclature of others, and in some cases the very species has been proved to be erroneous and to require correction.

During the summer of 1866 we found ourselves among those who were trying to escape the hot weather of July by a trip to the Saguenay. The few hasty notes of insects taken during this journey must necessarily be very imperfect, since a day or two at most was all the time that could be devoted to any one locality.
