This very distinct species of Campylopterus, the largest Humming-Bird of our 
region, was discovered by Deppe in Mexico, and very briefly described by Lichtenstein 
in 1830, in his list of that collector’s duplicate specimens, under the name it now 
bears. A few years later, in 1839, the same species received another name (0. de- 
lattrii) from MM. Delattre and Lesson, based upon specimens obtained by the former 
traveller at Jalapa in Mexico. The bird is now known to be not uncommon on the 
eastern slopes of the mountains of the State of Vera Cruz, and thence southwards 
through Central America to the State of Panama, occurring also in the Sierra Madre 
del Sur in Western Mexico, and in the mountains of Guatemala stretching towards 
the Pacific Ocean. | 
According to Delattre, C. hemileucurus is only found at Jalapa during two months 
of the year; and this statement is confirmed by de Oca, who says it is common there 
during October and November, flying from nine o’clock in the morning until noon. 
We have, however, several specimens from Mateo Trujillo which were shot at Jalapa 
in July, and at Playa Vicente in February, and it also occurs on the Isthmus of 
Tehuantepec in the latter month. Other dates of capture, both in Mexico and 
Guatemala, tend to show that this bird probably does not migrate in any wide sense of 
the term, but moves from place to place as certain flowers come into bloom. 
At Coban, in Guatemala, C. hemileucurus is common during the month of November, 
feeding from the flowers of the various species of Salvie which there abound. It 
also occurs in the heavily-forested region which lies to the northward, and in the 
forests of the volcanoes of Guatemala, and as low as 1000 feet on that side of the 
Cordillera which extends to the Pacific Ocean. Its range in altitude is thus great, as 
it reaches to at least 8000 feet above sea-level.
