The present species is from Ecuador, and is, as far as I know, only represented in collections by the single typical specimen in the possession of Mr. Elliot. It belongs to the section of the genus Eriocnemis with white puffs on the legs, and is distinguished further by its metallic yellowish-green throat, its general coppercoloured plumage, steel-blue tail, and shining blue under tail-coverts.
The following description is taken from Mr. Elliot’s ‘Synopsis:’—
Upper and lower surfaces metallic fiery copper-colour; chin and throat metallic yellowish-green, golden yellow in some lights; upper tail-coverts luminous yellowish green; under tail-coverts white on their basal half, rest blue; wings purplish brown; tail much forked, steel-black; tarsal tufts pure white; bill black. Total length 4\(\frac{1}{4}\) inches, wing 2\(\frac{1}{4}\), tail 1\(\frac{3}{4}\), bill \(\frac{7}{8}\).
