Published online by Cambridge University Press: 31 May 2012
Extract
In a recent paper (1931, Can. Ent., LXIII, 30 et seq.) I reviewed the bicolor group of the genus Ephemerella and in the present one I purpose dealing with the remainder of our eastern species and tabulating the results of breeding experiments, carried on during the past three years by Messrs. Walley, Milne and myself, as far as they relate to this genus.
