 Syhania, Nuttall, Man. Orn. I, 1832. Type Muscicapa ruticilla. 



Ch. — Bill depressed ; broader than high ; rictus with long bristles. Wings rounded, equal to or shorter than the tail; first 

 quill shorter than the fourth. Tail long; somewhat graduated, the outer feather^ about .20 of an inch or more shorter; all the 

 feathers unusually broad, and widened at the end. Feet short; tarsus shorter than the head. Hind toe equal to the lateral. 

 Coloration embracing more or less of red in northern species. 



This genus differs from Myiodioctes chiefly in the longer broader tail, and rather shorter tarsi 

 and toes, the hinder especially. The hill is more muscicapine ; the culmen nearly straight to 

 the abruptly decurved and much notched tip ; the gonys straight. In Myiodioctes the vertical 

 outlines are more convex ; the gonys more ascending ; the tip gently and but slightly 

 decurved. 



The species of this genus are all characterized by the brilliant red, yellow, black, &c. , of 

 their plumage, and, according t-o Kaup, (Pr. Zool. Soc. 1851, 49,) may be divided into 

 geographical groups, characterized by the prevalence of particular colors. The South American 

 species have more or less of yellow. The Mexican are usually black and red, without any pure 

 yellow.
