A DISSERTATION ON NORTHERN BUTTERFLIES

Abstract

The meeting with Papilio turnus on the Island of Anticosti, astonished me, as I did not expect to find this butterfly so far north in the Gulf of St. Lawrence. Only two specimens were taken during the season. and old settlers say that it is ahvays rare. Anticosti is evidently its most northerly limit, as it does not occur on the opposite shore of Labrador. It is common at Halifax, N. S., and in many localities along the south side of the St. Lawrence, until we reach the lake and rocky regions on the heighth of land from which the Assomption river flows north of Montreal.
