“ They are an obvious and very natural family, though the species are as yet but little understood, and not one half of them described. I have observed a singular peculiarity in a great many of these insects, which is, that when they are at rest in the sun, the lower wings are constantly in a quick vibrating motion up and down, as if the insect was rubbing them together, more particularly where the two lobes (or obtuse tails) of the under wings meet, though what purpose this is intended to accomplish remains unknown. ”

“ T. alis fuscis, colore violaceo nitidis, posticis caudatis, margine rubro, subtus maculo nigro lunulâque rubrâ ornatis; lobo anali suprà ærato, subtus nigro. Wings brown, glossed with violet; posterior tailed, with a red margin, beneath with a black spot and red lunule, anal lobe above bronzed, beneath black. ”
