nearly even and of about the same length as the wings. Three species are included in 

 Myiodioctes at the present time ; but a fourth was described by Wilson as Muscicapa 

 minuta, which has not since been recognized. All are of migratory habits, passing the 

 breeding- season in North America and the winter in Mexico and Central America, one 

 only at this season migrating as far south as Ecuador.

The presence of this species in Mexico is not fully established, though we have little 

 doubt that it was this bird that Mr. Lawrence called Myiodioctes ccerulescens in his list 

 of Prof. Sumichrast's Tehuantepec birds. The other Mexican reference, resting as it 

 does on the doubtful authority of Verreaux, requires further confirmation, as the bird 

 has hitherto escaped the notice of all the many good collectors who have worked in 

 Southern Mexico. In Guatemala M. canadensis is one of the well-known winter 

 visitants, where it is to be found frorn September to the following spring at elevations 

 ranging from 800 to 5000 feet above the sea, its chief resort being the second-growth 

 woods. In Costa Eica and in the Isthmus of Panama it is also known as a winter 

 immigrant ; but it passes at this season far beyond the limits of our fauna, being found 

 in Colombia ^ and in the province of Loxa on the southern confines of Ecuador 2. 



In North America it is known as a bird of passage in the eastern States during its 

 spring and autumn migrations. A few stop to breed in the State of New York and in 

 Massachusetts, the rest northward of these States ; but the extension of the northern 

 range of the species is not ascertained, but probably coincides with the limit of trees, 

 or lat. 54° N.io.
