the branches after insects. From the specific name given them it is 
probable that they are more plenty in Canada than in the United States ; 
where it is doubtful whether they be not mere passengers in spring and 
autumn. 
This species is four inches and a half long, and eight in extent ; front 
black; crown dappled with small streaks of gray and spots of black ; line 
from the nostril to and around the eye yellow ; below the eye a streak 
or spot of black, descending along the sides of the throat, which, as well 
as the breast and belly, is brilliant yellow, the breast being marked with 
a broad rounding band of black, composed of large irregular streaks ; 
back, wings and tail cinereous brown; vent white; upper mandible 
dusky, lower flesh colored ; legs and feet the same ; eye hazel. 
Never having met with the female of this bird I am unable at present 
to say in what its colors differ from those of the male. 
Species XV. MUSCICAPA PUSILLA* 
GREEN BLACK-CAPPED FLYCATCHER. 
[Plate XXVI. Fig. 4, Male.] 
This neat and active little species I have never met with in the worka 
of any European naturalist. It is an inhabitant of the swamps of the 
Southern States, and has been several times seen in the lower parts of 
the states of New Jersey and Delaware. Amidst almost unapproachable 
thickets of deep morasses it commonly spends its time, during summer, 
and has a sharp squeaking note, nowise musical. It leaves the Southern 
States early in October. 
This species is four inches and a half long, and six and a half in 
extent ; front line over the eye and whole lower parts yellow, brightest 
over the eye and dullest on the cheeks, belly and vent, where it is 
tinged with olive ; upper parts olive green ; wings and tail dusky brown, 
the former very short ; legs and bill flesh colored ; crown covered with 
a patch of deep black ; iris of the eye hazel. 
The female is without the black crown, having that part of a dull 
yellow olive, and is frecpiently mistaken for a distinct species. From 
her great resemblance, however, in other respects to the male, now first 
figured, she cannot hereafter be mistaken.
