I have described the genus Tripudia in the Can. Ent., but the characters are not obvious until we know the neuration, which I am satisfied will give us distinguishing features from Eustrotia and Thalpochares. Compared with these the front is narrow and a little bulging; the vestiture is scaly, and there is a ridge of scales on the occiput. The lashless naked eyes, the slender unarmed tibiae agree with its allies. The wings are entire and there is a velvety band on the primaries, not legible, however, in two minute, pyralidiform species which may not be different, my flavofasciata and Mr. Edward's versuta. The species are only known to me as yet from single examples, and are from the South. Limbata has the hind wings orange; the rest fuscous or blackish, silky.
