Bristles reach half way from nostril to tip. Culmen almost straight to near the tip ; commissure very slightly curved. Nostrils oval, with membrane above them. Wings rather longer than tail, pointed ; lid, 3d, and 4th quills nearly equal; 1st intermediate between 4th and 5lh. Tail rather long, rather rounded ; the featliers broad, and widening at ends, the outer web narrow. Tarsi with scntellar divisions indistinct externally. Legs slender; toes short, inner cleft nearly to base of 1st joint, outer with Ist joiut adherent; middle toe withont claw, not quite half the tarsus. The description above given is based upon the tj'pe of the genusâ S. ruticilla. Of the many speci " referred by authors to Setophaga the only one that corresponds with it in most of those characters is the Mexican S. picta. This is quite similar in most points, but differs in the wing being a little less pointed, the 1st quill about equal to or a little longer than the 5th. The feet arc quite diifer- eiitâthe toes being considerably longer, so that the middle toe with- out claw is two-thirds the tarsus. The claws are proportionally longer, perhaps less curved, and the scutellaj more distinct on the outside of tarsus. The South and Middle American species, hereto- fore assigned co this genus, are all characterized by peculiar features readily distinguishing them from S. rulicilla, and are certainly entitled to subgeneric rank. As far as I now recollect S. ruticilla is the only one of the Seto- phagem in which the sexes are certainly dissimilar. The rule is the reverse in the other SylmcoUdse. In
