1 Phcethornis SWAINS., Zool. Jour. 1827, 357. Type, Trochilus svperciliosus LINN. (One species in southern 

 Mexico, and numerous species farther south.) 



2 EupTierusa GODLD, Mon. Troch. pt. xiv. 1857. Type Ornismya eximia DELATTR. (One species in southern 

 Mexico, another in Guatemala, a third in Costa Rica and Veragua.) 



3 Abeillia BONAP., Consp. i. 1850, 79. Type, Ornismya abeillei DELATTR. (One species in southern 

 Mexico and Central America.) 



4 Sphenoproctus CAB. & HEIN., Mus. Hein. iii. 1860, 11. Type, Ornismya pampa LESS. (One species in 

 southern Mexico, another in Guatemala.) 



5 Lamprolaima REICH., Aufz. der Colib. 1853, 9. Type Ornismya rhami LESS. (One species in highlands of 

 Mexico and Guatemala. This is possibly the species referred to in " Birds of the North-West," p. 273, but 

 erroneously identified by Dr. Coues as Eugenes fulgent, as follows : " Mrs. Maxwell, of Boulder [Colorado], 

 . . . informs me that she has seen on two or three occasions a Hummingbird with a flaming-red throat and 

 breast, much larger than the present species [Selasphorus platycercusi], a straggler from Mexico, perhaps, as yet 

 undetected within the limits of the United States.")
