Theil iii. p. 24. Habitat. Brazil. ‘The three species constituting my genus Panoplites very closely resemble each other in size, in structure, and in the markings of their tails, but are very dissimilar in the colouring of their bodies. They are all inhabitants of the Ecuadorian Andes, and one of them (P. flavescens) extends its range as far north as Bogota. The most remarkable species of this form is the P. Jardinei, whose glittering upper surface is wonderfully brilliant. Genus Panopuites, Gould. (IlavorAirns, omnino armatus. ) Generic characters. Male.—Bill strong, and a trifle longer than the head; body stout and thick-set ; wings long and pointed ; tail moderately long and square, the feathers broad; tarsi clothed and stout; hind toe strong, and of the same length as the middle one; nails short. Female.—Very similar to the male in plumage. 128. PanopuitEes JARDINE! . : : : : : Y ; : : ; i : Vol. II. Pl. 110. Panoplites Jardine, Cab. et Hein. Mus. Hein. Theil iii. p. 75, note. Habitat.

Somewhat allied to the Panoplite are the members of the Genus Fiorisuea, Bonap., all of which are remarkable for their large fan-shaped tails, and for having all the feathers of this organ white. The females are less strikingly coloured. One of the species, F. mellivora, enjoys a most extensive range ; for it inhabits alike the low lands of Northern Brazil, Cayenne, Guiana, Trinidad, Venezuela, the temperate regions of New Granada, and Central America; the other two are confined to more limited areas. The F. mellivora and F. atra are among the oldest-known and the commonest of the Humming-Birds, there being no collection of any extent without examples of them. 131.
