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 Trochilidse ' two years afterwards ^. It was next discovered 

 in Cosfa Rica by Von Frantzius '^ ^ and other collectors, and subsequently Arce sent us 

 a good series of examples from Chiriqui ^. 



In some respects S. scintilla is like S. alleni 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
