Extract

Work undertaken in connection with Mr. C. P. Kimball's projected list of Florida Lepidopera has revealed a number of problems in the North American species usually referred to Diasemia Hübner ([1824-25] p. 348), type Pyralis literalis Denis and Schiffermüller (=Phalaena litterata Scopoli) (Figs. 1, 2). A structural study shows that these species belong to five groups, generically distinct from one another and from the type species of Diasemia. Diasemia alaskalis Gibson (Fig. 3) is congeneric with Udea ferrugalis (Hübner) and should be known as Udea alaskalis (Gibson), new combination. I have characterized the genus Udea Guenée in an earlier paper (Munroe, 1950). Diasemia plumbosignalis Fernald (Fig. 10) and related species belong to the genus Choristostigma Warren, 1892: 440. The species of Choristostigma will be discussed in a separate publication. Diasemia magdalena Fernald and an undescribed species belong to the genus Daulia Walker (1859: 975) hitherto known from the tropics of the Old World and from Argentina. Hydrocampa ramburialis Duponchel and Desmia? janassialis Walker require new genera.
