We have here a curious and inexplicable case of dimorphism, for some of the females of four European species of Dytiscus, and of certain species of Hydroporus, have their elytra smooth; and no intermediate gradations between the sulcated or punctured, and the quite smooth elytra have been observed. See Dr. H. Schaum, as quoted in the 'Zoologist, vols. v.-vi. 1847-48, p. 1896.
The small standing waters, formed by single cavities, are proportionably rich in water-beetles, among which is found a Dyticus of the form of the sulcatus, seven Colymbetes, Hydroporus two species, and a Gyrinus.
