SCISSAR-TAIL, OR SWALLOW BLACK-CAP. 93 
guay have given, it the name of Yetcipa, or the Scis- 
sar-tail. When perched, it has the distinguishing 
habit of the flycatchers, of darting upon such insects 
as pass within its range of wing, without, as it would 
seem, pursuing them. It is common in Paraguay, 
and not unfrequent in Southern Brazil. 
The general colour of the upper plumage, except- 
ing the wings and tail, is light cinereous, tinged 
with grey ; this latter tint is chiefly caused hy the 
shaft of each feather being brown. The under plu- 
mage, from the bottom of the neck downwards, is of 
the same colour as the hack, hut towards the belly 
and vent it gradually changes to a dull white. Prom 
the chin to the bottom of the neck, which is very 
short, the feathers are pure white, this part being 
confined by a crescent of the deepest chestnut, which 
commences on the ears and crosses the upper part 
of the breast. Above the eye is a whitish stripe, 
hut the lores are grey ; the inner wing-covers, and 
the margins of the wings, are white ; the wing- 
covers, scapulars, spurious wings, and most of the 
lesser quills, are dark sepia-brown ; but the prima- 
ries, excepting the two outermost, are of an orange- 
buff colour, tipt only with brown ; the tail is brown 
towards the base, but black beyond. 
Total length, 15 inches ; bill, gape, 1 ; front, T 6 5 ;
