Genus SERICOTES Reichenbach.
- [Anthracothorax] γ. Sericotes Reichenbach, Aufz. der Colib., 1854, 11. (Type, Trochilus holosericeus Linnæus.)
Rather large Trochilidæ (length about 100-120 mm.) very closely related to Eulampis, but differing in more naked tarsi, rounded, instead of emarginate, tail and very different coloration, the remiges nonmetallic, and general coloration green, the upper tail-coverts blue and a blue or violet patch on chest.
Bill longer than head, rather stout, nearly terete but broader than deep at base, distinctly decurved; culmen rounded but basally contracted into a narrow ridge; terminal portion of maxillary tomium minutely serrate; mandible with a broad longitudinal median groove. Nasal operculum narrow, concealed by dense appressed frontal feathering, which extends to or slightly beyond anterior end of nostril, forming a short and narrow point or antia on each side of mesorhinium. Tarsus naked except for upper frontal portion; middle and inner toes about equal in length, the outer slightly shorter, the hallux shorter than outer toe. Wing about three times as long as exposed culmen, the outermost primary longest. Tail decidedly more than half as long as wing, slightly but distinctly rounded, the rectrices broad, with nearly truncate tip, the lateral rectrices strongly incurved.
Coloration. — General color green (brighter below), but this relieved by a blue or violet jugular patch, the tail-coverts also blue or greenish blue; tail blue-black or violet-black. Sexes alike.
