 Myiabeillia Bonaparte, Rev. et Mag. de Zool., vi. May, 1854, 253. (Type, Ornis- 



mya abeillei Delattre and Lesson.) 



Small Trocliilidse (length about 68-75 mm.) very closely related to 

 Klais, but with tail relatively longer (three-fifths to nearly two- 

 thirds as long as wing), more distinctly emarginate or double-rounded 

 in adult male, the latter with pileum metallic green (concolor with 

 back, etc."! the chin and upper throat bright metallic emerald green. 



Bill shorter than head, straight, terete; culmen rounded except 

 basally, where contracted into a rather distinct ridge; tomia smooth; 

 mandible with the usual lateral median groove. Nasal operculum 

 moderately broad, strongly convex, only the inner portion hidden by 

 the decumbent frontal feathering, which extends anteriorly nearly to 

 anterior end of nostril, forming a single broad, rounded, frontal 

 antia. Tarsus feathered, except on posterior side; anterior toes about 

 equal in length, but the outer apparently appreciably shorter. Wing 

 about four times as long as exposed culmen, the outermost primary 

 longest, normal in shape. Tail of adult male nearly two-thirds as 

 long as wing, deeply emarginate, with lateral rectrices shghtly shorter 

 than the next, that of adult female moderately rounded, with middle 

 rectrices shghtly shorter than the next, the rectrices (in both sexes) 

 broadly rounded terminally. 



Coloration. — Above metallic bronze-green, including middle rec- 

 trices and basal portion of other rectrices, which are blackish subter- 

 minally and grayish terminally; a small white postocular spot. 

 Adult male with chin and upper throat bright metallic emerald green, 

 the remaining under parts ohve-grayish strongly glossed with bronze- 

 green (more dusky on lower throat); adult female with under parts 

 pale gray, the outer rectrices more abruptly tipped with gray. 



Range. — Southern Mexico to Guatemala. (Monotypic.)
