A new subspecies, Helicoverpa pallida nihoaensis, from Nihoa Island, Hawaii, is described. Additional distributional data for Helicoverpa zea (Boddie) in Hawaii are presented, and pupal diapause in a Sudan population of H. armigera (Hbn.) is discussed. The present generic assignment of Heliothis pauliana Viette is questioned, and Chloridea chilensis (Hamp.) is transferred to the genus Schinia.
