The generic title Burtia was proposed by me in the first part of the Notes on the Zygænidæ of Cuba, read February 12, 1866, before the Ent. Soc. Phil., and published in July of the same year. The genus is, however, incorrectly dated “1867” by Kirby in his catalogue of 1892, where B. rubella seems also wrongly given as a synonym of Gundlachia cruenta, H.-S., the two species being presumably distinct. Now, Moeschler had previously, in 1890 (Lep. Porto Rico, p. 349), given “Horamia plumosa, H.-S.,” as a synonym of B. rubella, and “G. cruenta” as a synonym of Callicarus pennipes, thus according to my paper priority over Herrich-Schaeffer's in the Correspoudenz Blatt, although these reversed references may chiefly show that Moeschler could not make out H.-S. descriptions, which are usually scanty.
