About the middle of May, 1883, Mr. A. W. Hanham took a ♀ T. Niphon a few miles from the City of Ottawa. This was the only specimen at that time seen.

On the 4th May last, when walking along the Chelsea Road, near the village of Chelsea, P. Q., with Mr. Harrington, he called my attention to a small butterfly which had just alighted on the bare road in front of us. This I was delighted to recognise as Niphon. Having no nets with us, a too near approach was only rewarded with the mortification of seeing the coveted prize flit lightly up to the top of some high pine trees. Subsequent to this date the weather was cold aud wet for some time, and I had no opportunity to visit the locality until the 22nd of the month.
