The essential character of this group has been indicated on 

 a preceding page. It has usually been associated with PHlo- 

 gonys and Phmnopepla in 

 the family [Ampelidce) 

 which contains the Ce-

 William Jardine's "Naturalists' Library". It consists of ten or

 others being more southerly. In addition to the characters just 

 noted, it may be observed that the species of Myiadestes agree 

 in their rather uniform dark or dull coloration, variegated with 

 brighter tints on the wings. They form part of an interesting
