ERGATICUS.—MYIODIOCTES. 165 
In Mexico this species is characteristic of the alpine regions, being common at eleva- 
tions ranging between 6500 and 10,000 feet. Prof. Sumichrast speaks of it as fre- 
quently met with in the pine-woods, which it enlivens by the brilliancy of its plumage 
and the graceful vivacity of its movements!©, Though most collections from Southern 
Mexico contain specimens, we have no further account of its habits, nor is any thing 
known of its nidification. |

The first specimen we obtained of this pretty species was shot during an excursion 
to the forests of the Volcan de Fuego, when we were staying at Duefias, in October 
1861. It was found in a patch of alder trees on the slopes of the mountain, at an 
elevation of about 7000 feet. We subsequently met with it in the same forests, but 
usually at a greater altitude, as high as about 10,000 feet, where the mixed forest 
terminates and the pines commence. It frequents the lower vegetation rather than the 
tops of the forest trees. It searches diligently for insects much after the manner of a 
Setophaga; but it occasionally remains at rest on a twig, its brilliant red plumage 
showing conspicuously amongst the green foliage of the surrounding trees. Of its 
nidification nothing is as yet known. Besides meeting with F. versicolor in the Volcan 
de Fuego we also found it in several other districts of Guatemala, such as the 
neighbourhood of Solola, at an elevation of about 7000 feet, and in the mountains 
above Totonicapam as high as 10,500 feet above the sea. In both these places it 
frequented pine-forests. . versicolor has never to our knowledge been obtained by 
the Coban bird-hunters; but we ourselves met with it in the high mountainous district 
of Chilasco, at an elevation of about 6000 feet. Here, as in the Volcan de Fuego, it 
resorted to the upland forests rather than the pines.

The members of this genus have the rictal bristles well developed, but not so much 
so as in Setophaga. The bill is broad, and depressed rather than flattened, the tail
