Eight species of Nearctic Eucosmini previously considered to be of uncertain generic assignment are reviewed and illustrated. The following new or revised combinations are proposed: Pelochrista aspidana (Walsingham), comb.n.; Eucosma delphinoides (Heinrich), comb.n.; Eucosma delphinus (Heinrich), comb.n.; Pelochrista excerptionana (Heinrich), comb.n.; Pelochrista fuscana (Kearfott), comb.n. and new synonymy with Pelochrista nandana (Kearfott); Eucosma sublapidana (Walsingham), comb.rev. Eucosma apriliana (Grote) and Eucosma gomonana Kearfott retain their former generic placements. Eucosma baggetti, a new species similar to Eucosma gomonana Kearfott, is described from southeastern United States.
