Abstract The North American species of Udea are revised on the basis of about 2500 specimens, with strongest representation in the difficult itysalis group. Twenty-three species and an additional 19 subspecies are recognized. Of these, the following six species and 18 additional subspecies are described as new: U . washingtonalis hollandi , interior B.C. and Mont.; U . w . nomensis , Alaska; U . w . pribilofensis , Pribilof Is.; U . indistinctalis johnstoni , Wash., ? Sask.; U . brevipalpis , Colo., Utah and ? Calif.; U . cacuminicola , Colo., Wyo.; U . beringialis , Yukon, Alaska; U . derasa , B.C.; U . livida , B.C., Wash., Utah; U . turmalis catronalis , N. Mex.; U . i . tularensis , Tulare Co., Calif.; U . t . griseor , Calif.; U . itysalis mertensialis , N.S.; U . i . rindgeorum , Tooele Co., Utah; U . i . kodiakensis , Alaska; U . i . albimontanensis , Ariz., N. Mex.; U . i . durango , Colo., Utah; U . i . wasatchensis , central Utah; U . i . clarkensis , southern Nev., Calif.; U . i . marinensis , San Francisco Bay region, Calif.; U . abstrusa subarctica , Northwest Territories, Yukon; U . abstrusa abstrusa , Alta., Sask., Man.; U . a . cordilleralis , Wyo., Colo., Utah, N. Mex.; U . a . pullmanensis , Wash. Five nominal species are transferred from other genera to Udea : Botis octosignalis Hulst, from Pyrausta Ebulea straminea Warren, from Calamochrous Botis vacunalis Grote, from Pyrausta Phlyctaenia rusticalis Barnes and McDunnough and P . berberalis Barnes and McDunnough. U . straminea (Warren) is synonymized with U . octosignalis (Hulst) and U . galactalis (Dyar) with U . vacunalis (Grote). U . turmalis (Grote) is separated specifically from U . itysalis (Walker). Phiyctaenia angustalis Barnes and McDunnough is transferred from Udea to Evergestis .
