I was much interested in an article in Vol. xiii. of the Canadian Entomologist, by Mr. W. H. Edwards, entitled. “Is Limenitis arthemis double-brooded?” My own observations previous to the time of reading the article were confirmatory of Mr. Edwards' theory; but I wished to learn more of this interesting species before hazarding any remarks concerning its habits.

I have never reared or attempted to rear arthemis from the egg, but have one specimen obtained from a full-fed larva found on the 2nd July, 1877. It went into chrysalis on the 3rd, and the imago appeared on the 16th, I have seen fresh looking specimens on 1st July, when enjoying, with other citizens, “Dominion Day” in the country. Later than this I have not seen a fresh specimen, excepting the example before recorded.
