The largest species of the luminous lilac-throated Peruvian Humming-Birds, the R. Vespera, constitutes the genus Rhodopis, which, as the form differs from all the others, I have no other alternative, if I act with consistency, than to adopt. It has a deeply forked tail, the feathers of which are narrow and rigid, not soft and yielding as in the T. Coræ. I have never seen a second species of this particular form. The female, like that sex in many other allied genera, is destitute of brilliant colouring.
