There appears no end to the immense number of species referrible to this genus, which will perhaps be found the most extensive tropical group of all the Linnæan Phalænidæ. Of these, near eighty species I found in Brazil; Dr. Horsfield has brought a great many from Java; near fifty are found in North America, and I have little doubt that the whole number existing in the cabinets which I have inspected may amount to about three hundred and fifty. The thorough investigation of these is a work of no ordinary labour; and, until this is done, it appears most advisable to let the generic distinction remain, as given by Latreille, though there can be no doubt that among them distinct groups will be detected.
Cramer's figure will not indicate even the genus, and Fabricius describes the body as white; the tip ferruginous; in this it is yellow, tipped with red.
Mr. Haworth obliged me with this insect, which Fabricius notes as African.
