Specimens of this species from all parts of our region are very uniform in their colora- 
tion, but in the northern portion of South America the rufous colour of the outer surface 
of the wings is more developed, and thus a species or race has been separated under the 
name of P. rufipennis. It is somewhat remarkable that no specimens of this form have 
_ yet been found in Panama, Costa Rica being the southern recorded limit of P. derbianus. 
From this it would appear that the ranges of the latter species and of P. rufipennis are 
separated by a considerable interval. ‘The northern limit of the range of this Tyrant 
extends to the lower Rio Grande valley, and we have many specimens from the frontier 
States of ‘Tamaulipas and Nuevo Leon; thence it spreads all through the hot and 
temperate regions on both sides of the Cordillera, its limit in altitude reaching about 
5000 feet. Grayson says:—‘ This is a common and abundant species, inhabiting the 
western and north-western parts of Mexico. I found it equally as common in Tehuan- 
tepec as in the region of Mazatlan, where its loud shrill notes of hip-see-dee hip-see-dee 
may be heard at all seasons of the year, but more particularly during the breeding- 
season, when it is excessively garrulous. It is more frequently met with in the neigh- 
bourhood of freshwater streams and lagoons, and I have often seen them dart into the 
water after water-insects and minnows that were swimming near the surface not unlike 
a Kingfisher, but they usually pursue and capture on the wing the larger kinds of 
Coleoptera and Neuroptera, swallowing their prey entire after first beating it against 
a branch. They are usually in pairs, but I have also seen as many as twenty about a 
‘stagnant pool watching its turbid water for insects and small fish, for which they seem 
to have a great partiality.”
