Genus SERICOTES Reichenbach. 

 ''Anthracothorax] y. jSericotes Reichenbach, Aufz. der Colil)., 1854, 11. (Type, 

 Trochilus holosericeus Linnaeus.) 



Rather large Trochilidae (length about 100-120 mm.) very closely 

 related to Eulamjns, but differing in more naked tarsi, rounded, 

 instead of emarginate, tail and very different coloration, the remiges 

 nonmetallic, and general coloration green, the upi)er 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 ])ortion; 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.
