While engaged on an Insect Faunal Survey with Mr. W. J. Brown in the northeastern section of New Brunswick, we ran across a very interesting race of Coenonympha inornata on the salt marshes a few miles north of Bathurst. The butterflies were emerging in large numbers during the first week of August, a very late date for Coenonymphas, and were very definitely restricted to the salt meadows or marshes which lie just back of the coast in this region.
