Published online by Cambridge University Press: 31 May 2012
Extract
In describing Agabus vancouverensis mihi, and in separating it from hypomelas and irregularis Mannerheim (Canad. Ent. 69 (7) : 146-150, four text figs. July, 1937), I did not give a key to the specics, and failed to note certain diagnostic characters. Since then the known distribution of the species has been considerably extended, as reported below.
