Read before the Entomological Society of Canada, April 16th, 18638. 
In pursuance of the plan first adopted by Prof. Hincks, of col- 
lecting and publishing in the “Journal” materials for a complete 
synopsis of our Canadian Entomological fauna, the following paper 
has been prepared; with the hope that it may be of some assistance 
to collectors, by enabling them more readily to determine their 
specimens, and also do something towards clearing up some hitherto 
doubtful points in connection with the specific characters of several 
species belonging to this beautiful and interesting family of Moths. 
The method of taking up, from time to time, certain families or sub- 
families of insects, and publishing descriptive lists of all the known 
Canadian species, including those likely to occur in Canada, is, we 
believe, a good one, and we feel sure that if continued it will greatly 
stimulate the growth of our favourite branch of science. We trust 
that those who have time and opportunity will assist us in the work, 
for the field is a wide one, and there is ample room for all to labour 
profitably. 
In the preparation of this paper, free use has been made of the 
material collected by Dr. Morris, in the late Smithsonian “ Synopsis 
of North American Lepidoptera,” and also of that contained in 
Dr. Clemens’ “Contributions to American Lepidopterology,”’ pub- 
lished in the Proc. Acad. Nat. Sciences. We would also acknow- 
ledge our indebtedness to the many kind friends who have freely 
placed their specimens at our disposal. The collection thus gath- 
ered from various parts of the Province, has materially aided in 
making the list of Canadian species much more complete than it 
otherwise could have been, and also sequerabe us with many in- 
teresting variations. 
Fam. Arctiadae.—Herr-Schaef. Chelonides Boisd.
