The early months of 1880 were especially favorable to the acquisition of the hybernating Coleoptera, and those which have their permanent habitat among the moss of our woods and swamps. The early disappearance of the snow laid bare their hiding places, while the frosts which succeeded formed an ice-bridge which gave access to their places of refuge, which in ordinary seasons remain covered with snow tiil the general break-up of the winter, when they are rendered inacessible by being surrounded or covered with water.
