Genus PHÆNOSTICTUS Ridgway.
- Phænostictus[1] Ridgway, Proc. Biol. Soc. Wash., xxii, Apr. 17, 1909, 70. (Type, Phlogopsis mcleannani Lawrence.)
Medium-sized or rather large Formicariidæ (length about 190 mm.) with bill stout and about as long as head, tail nearly as long as wing, tarsal scutella fused, sides of head naked, and with back and under parts conspicuously spotted with black.
Bill about as long as head, rather stout, moderately compressed terminally, its width at latero-frontal antiæ decidedly less than its depth at same point; culmen distinctly (almost sharply) ridged, nearly straight for most of its length or very slightly convex subbasally, decurved terminally, the tip of maxilla moderately uncinate; maxillary tomium nearly straight, slightly notched subterminally; mandibular tomium straight, minutely notched subterminally; gonys decidedly convex and prominent basally, faintly convex and ascending terminally. Nostril exposed, posteriorly in contact with thin feathering of latero-frontal antiæ, broadly oval, margined above by a rather broad extension of the membraneous integument of the nasal fossæ, an internal tubercle showing distinctly within posterior portion. Rictal bristles absent, but feathers of loral region with stiffened, bristle-like shafts. Wing moderate or rather large, with longest primaries extending considerably beyond secondaries; sixth, or fifth, sixth and seventh, primaries longest, the tenth (outermost) nearly two-thirds as long as the longest, the ninth about as long as secondaries. Tail of 12 rectrices, nearly as long as wing, graduated (graduation equal to length of tarsus or for about two-fifths its length), the rectrices rather narrow, rounded terminally. Tarsus a little more than one-third as long as wing, stout, booted (nonscutellate); middle toe, with claw, decidedly shorter than tarsus; outer toe, without
claw, reaching to about middle of subterminal phalanx of middle
