Eight closely related species of Eucosma Hübner are reviewed: E. refusana (Walker), E. decempunctana (Walsingham), E. amphorana (Walsingham), E. annetteana (Kearfott), E. autumnana (McDunnough), E. citricolorana (McDunnough), E. scotiana (McDunnough), and E. verna Miller. Eucosma scotiana is recognized as a junior synonym of E. annetteana, and two new members of the group, Eucosma litorea sp. n. and Eucosma millerana sp. n., are described. Distributional patterns and biogeographic relationships for members of the group are discussed.
