In their geographical distribution the members of Seto- 

 phaga are almost wholly confined in North America to the 

 highlands of Mexico and Central America, and in South 

 America to the Andes, from Columbia to Bolivia. The sole 

 exceptions are : — S. ruticilla, which, passing the summer in 

 Eastern North America and the winter between the equator 

 and the tropic of Cancer, is a strictly migratory species ; and 

 S. castaneocapilla, which is peculiar to the highlands of 

 British Guiana. To these may be added ;S^. albifrons, which 

 is restricted to the isolated highlands of Merida, in Venezuela. 

 In the country north of the isthmus of Panama we have 

 three species peculiar to Mexico, the territory immediately 

 north of it, and Guatemala, viz. S. picta, S. miniata, and 

 S. lacrymosa ; and in Costa Rica and Veragua, S. aurantiaca 

 and S. torquata. In the United States of Columbia S. chrysops, 

 S. ornata, S. ruficoronata, and S. verticalis occur. In Vene- 

 zuela, besides S. albifrons, already mentioned, ;S^. verticalis 

 is found ; in Ecuador, ;S^. verticalis, S. ruficoronata, and 

 S. bairdi ; in Peru, S. verticalis and S. melanocephala ; and 

 in Bolivia, /S. verticalis, S. brunneiceps, and S. melanocephala. 

 It will thus be seen that the majority of the species have a 

 very restricted range, and that the genus is wliolly unrepre-
