A New Species of Dytiscus Linn. (Coleoptera, Dytiscidae)

Extract

For a number of years, at least one species of Dytiscus, apparently undescribed, has been in my collection.

Recently Professor M. H. Hatch asked me to describe this species in order that he might include it in his forthcoming book on The Coleoptera of the Pacific Northwest.

Although Balfour-Browne, 1935, pointed out that the correct spelling of the generic name is Dyticus, this does not seem to have been accepted, as in the 5th Supplement to the Leng Catalogue, Dytiscus is still used. I, therefore, use that spelling.
