Genus SERICOTES Reichenbach. 
"Anthracothorax] 7. Sertcotes RetcHenBacu, Aufz. der Colib., 1854, 11. (Type, 
Trochilus holosericeus Linneus.) 
Rather large Trochilide (length about 100-120 mm.) very closely 
related to Hulampis, 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 con- 
tracted 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 feath- 
ering, which extends to or slightly beyond anterior end of nostril, 
forming a short and narrow point or antia on each side of mesorhin- 
ium. 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.
