Stelyidopteri/x fuloigula, Daihd, n. B. Hah, Costa Rica. (No. 34,677, %, Costa Rica.) Above smoky brown. Quills and tall feathers almost or quite black; rump with the feathers gray, edged with whitirth, forming a conspicuous contrast to the back. Chin, throat, and forepart of breast reddish fulvous; sides under the wings brown, with a decided wash of fulvous; axiUars and inside of wings smoky brown; rest of under parts dnll white, with perhaps a tinge of yellowish ; crissuiu pure white, in one specimen with a trace of a dusky spot at ends of longer tealliers. The edges of the feathers of upper parts, especially of the wing coverts and 8eoondary quills, are tinged with reddish fulvous, indicating immaturity, as does also the absence of the hooks on outer web of first primary. Judging from the analogy of other species, these edgings probably disappear entirely in full dress. (No. 34,(!77, % .)

The very conspicuous light rump will readily distinguish this species from all its allies, except uropygialis. It is, however, con- siderably smaller than that species and much darker above, especially on quills and tail feathers (on both surfaces and including the shafts), the light rump more conspicuous. The fulvous red of throat seems to extend further on the breast, the white of the belly to farther forward, the brown of the sides to be more restricted. The under coverts lack the conspicuous dusky band at tips of larger feathers. The conspicuous wash of reddish fulvous on the side may be from immaturity. â "'^'' It is barely possib
