A STUDY OF THE NORTH AMERICAN MOTHS FORMERLY REFERRED TO DELTA SAALMuLLER, WITH TWO NEW SPECIES (LEPIDOPTERA: PHALAENIDAE) By J. F. Gates Clarke Bureau of Entomology and Plant Quarantine, United States Department of Agriculture Since Hampson's work appeared in 1909^ the name Delia, proposed by Saalmiiller-for a phalaenid from Madagascar, has been appHed to certain moths from north and Central America. Because there are marked differences between the American moths and Saalmiiller's generic description, and since there ap-pears to be no available name for the group, I propose the fol-lowing new generic name for our American species.
