Sp. Char. Adult (♂, Costa Rica; Coll. G. N. Lawrence). Above bluish-plumbeous, the feathers darker centrally; anteriorly the black increases in extent, first leaving the plumbeous only as a border to the feathers, and then dropping it altogether, the head and nape being plain black; posteriorly the plumbeous predominates, and shows a tendency to form transverse bars. On the head and neck the black occupies the whole upper and lateral portions, reaching down to the throat, involving the whole of the cheeks and maxillæ, which it covers in an angular patch. Primaries and tail deep black; the former immaculate on their outer surface; the latter crossed by six (the last terminal) incomplete very narrow bands of pure white, formed by transverse bars, which touch neither the shaft nor edges of the feathers; upper tail-coverts crossed by about two bars of pure white. Immaculate area of the throat and jugulum deep rufous posteriorly and laterally, pure white anteriorly and centrally; from the jugulum to the tibiæ, and including the entire lining of the wing, continuous black, with transverse bars of white; tibiæ plain rufous; crissum mixed rufous and white,—the former predominating,—and thickly marked with large transverse spots of black; inner webs of primaries with transverse ovate spots of white, touching neither shaft nor edge of the feather; these number seven on the longest quill (second). Wing-formula, 2–1, 3–4. Wing, 9.90; tail, 5.50; tarsus, 1.55; middle toe, 1.75.
Juv. (♂, 51,293, Costa Rica, La Palma, August 25, 1867; José C. Zeledon). Whole upper surface black, deepest on the tail; it occupies the whole head (except the chin, throat, and sides of the neck), the black cheek-patch having considerable prominence; feathers everywhere (except on the head and neck) indistinctly bordered with light brownish, this becoming more distinct posteriorly; upper tail-coverts tipped and barred beneath the surface with pure white; secondaries, primaries, and primary coverts narrowly but sharply tipped with pure white; tail crossed with five very sharp bars of pure white, the last terminal, the first two concealed by the coverts; these transverse spots touch the shaft, but not the edge of the feather; on the lateral feather they are confined to the inner web. Chin, throat, neck, and breast, abdomen, crissum, and lower tail-coverts, deep orange (not chestnut) rufous; in fact, this forms the ground-color of the whole lower parts; but the sides, flanks, and abdomen have such large transverse spots of black (these exceeding the orange in amount), giving the prevailing color; the orange of the jugulum is sharply defined, with a semicircular outline, against the black of the belly, and has distinct lanceolate shaft-streaks of black; the lower part of the abdomen, and the tibiæ, have cordate or broadly sagittate black spots, rather exceeding the orange; the lower tail-coverts have broad transverse spots of black. (The orange is deepest on the jugulum and crissum, being palest where most thickly spotted; it is immaculate only on chin, throat, and neck; the markings are longitudinal only on the jugulum.) Lining of the wing like the belly, that is, the black predominating; under surface of primaries with transverse elliptical spots of pale cream-color, seven in number on the longest. Wing-formula, 2, 1–3. Wing, 9.90; tail, 5.40; culmen, .72; tarsus, 1.40; middle toe, 1.75; outer toe, 1.20; inner, 1.00; posterior, .80.
