Helminthophila rubricapilla. Descriptions of First Plumage of Cer- tain North Am. Bbs. Wm.Brewster. 25. Helminthophaga ruficapilla. First plumage: female. Remiges, rectrices, etc., as in adult. Two conspicuous wing-bands of bright buff. Pileum and nape light ashy, tinged with fulvous. Back ashy, just touched with green; rump bright olive-green. Supra-orbital line, ring around eye, and the throat, bright buff. Lores, maxillary line, and auriculars pale ashy. Breast and cris- um gamboge-yellow, each feather tipped with whitish, producing a some- what hoary appearance. Abdomen pale yellow; sides dull cinnamon, with a shade of ashy. From a specimen in my collection taken at Upton, Me., August 14, 1873. A full series of specimens illustrates well the progressive stages. The fall plumage is very quickly acquired by young of this species. Bull. N. O. C. 2, April, 1878. p. 57.
