LABINE Biomedical Data Processing Training Program, School of Public Health, The University of Michigan, Ann Arbor, Michigan Received December 15, 1967 This paper is one of a continuing series Similar data obtained from the literature investigating the population biology of and from personal communications for three Euphydryas editha (Nymphalidae: Nym other butterflies, Cercyonis oetus, Colias phalinae).
