Genus FLORISUGA Bonaparte. 
Florisuga Bonaparte, Consp. Av., i, 1850, 73. (Type, Trochilus mellivorus 
Linnzus.) 
Rather large Trochilide (ength about 95-110 mm.) with appar- 
ently twelve rectrices (the longer upper tail-coverts so elongated 
and specialized as to simulate the middle rectrices), tail equal to or 
longer than combined length of head and bill, emarginate, with 
rectrices broad, firm, and (at least in adult male) nearly truncated 
at tip, tarsi densely clothed with rather long feathers (especially 
behind), and abdomen white. 
Bill a little longer than head, rather stout, straight, nearly terete; 
culmen rounded except basally, where narrowly ridged; tomia 
smooth; maxilla and mandible each with a rather indistinct narrow 
median lateral groove. Nostril narrow, slit-like, overhung by a 
broad, tumid, almost wholly feathered operculum, only the edge of 
which is exposed. Tarsus wholly feathered, the feathering long on 
posterior portion; middle and inner toes about equal in length, the 
outer toe slightly shorter; hallux slightly shorter than outer toe; 
all the toes small and weak, with claws relatively small. Wing about 
four times as long as exposed culmen, the outermost primary longest. 
Tail a little more than half (female) as long as wing to nearly three- 
fifths as long (adult male), emarginate, the rectrices firm, very 
broad, broadly rounded or (in adult male) nearly truncated at tip; 
the rectrices apparently 12 in number (at least in adult male) through 
specialization of the two longest upper coverts, which are as long as 
and differently colored from the middle rectrices. 
Coloration.—Adult male with head and neck metallic violet-blue, 
back, scapulars, rump, and upper tail-coverts metallic green; breast, 
abdomen, flanks, under tail-coverts, and tail (including middle 
rectrices) white, the latter narrowly tipped with black; a white line 
across hindneck. Adult female and young with throat, chest, sides, 
and under tail-coverts dusky squamated with grayish white, pileum 
green, like back, etc., and tail dark metallic green crossed at or near
