(v. Frantzius *®), Tucurriqui (Arcé®), Cartago and Volcan de Irazu (Boucard *);

This beautiful little species was discovered by Warszewiez during his visit to the 
Volcan de Chiriqui, and his specimens were described by Gould in 1850, and figured 
in his ‘ Monograph of the Trochilide’ two years afterwards *. It was next discovered 
in Costa Rica by Von Frantzius’*® and other collectors, and subsequently Arcé sent us 
a good series of examples from Chiriqui>®. 
In some respects S. scintilla is like 8. allent of California on a small scale, but it 
may readily be distinguished by the flesh-coloured base to the mandible. 
M. Boucard, who observed this species in Costa Rica ®, says that it flies as high as 
10,000 feet on the Volcan de Irazu, and feeds from the flowers of small low-growing 
plants, making little noise with the vibration of its wings. He thought that by its 
silent low flight it escaped the notice of other Humming-Birds frequenting the same 
places.

The colour of the throat of this species is very peculiar, being of a lilac tint overcast 
with a leaden hue. It has all the appearance of being faded, but from the number of 
specimens we have seen this can hardly be so. Its nearest ally is no doubt S. scintilla, from
