The fossil occurrence of Helophorus arcticus Brown (Coleoptera: Hydrophilidae) in Pleistocene deposits of the Scarborough Bluffs, Ontario
Fossils of Helophorus arcticus Brown are described from Pleistocene deposits believed to be about 70 000 years old. This is the first record of the species as a fossil in North America. At present H. arcticus is known only from damp tundra regions of the subarctic in Canada, and it is suggested that...
