In the same salt meadows north of Bathurst, N. B., where Mr. Brown and I captured the recently described race of Coenonympha inornata (1939, Can. Ent., LXXI, 266) we took a series of specimens of L. dorcas Kby. which on examination, after spreading, appears to constitute an undescribed and rather strikingly different race. The butterflies were by no means common; the first specimens were taken on August 6, evidently freshly emerged, and by dint of careful searching during the next four or five days we were able to capture a series of about 50 specimens.
