STENOPSIS CAYENNENSIS INSULARIS Richmond. 



ISLAND STENOPSIS. 



Very much paler than S. c. cayennensis,^ with much less of dark 

 coloring on under parts. 



Adult male. — Pileum pale gray, suffused with pale buffy brown 

 (especially on center of crown), mmutely vermiculated with deeper 

 grayish br.own, and sharply streaked, except on lateral portions, with 

 black, these streaks sometimes edged or margined with ochraceous- 

 buff; a broad, unbroken, very conspicuous collar of ochraceous-buff 

 across hindneck; back and rump pale gray, suffused with pale buffy 

 brown indistinctly vermiculated with darker and with a few narrow 

 irregular streaks of blackish, the upper tail-coverts similar but paler 

 and clearer gray, with more distinct vermiculations, the mesial black 

 streaks with more of a tendency to form a chain of connected irregular 

 spots; scapulars, in part, similar in coloration to back, but many of 

 the feathers with outer web mostly plain buff and with a large sub- 

 terminal, uTegularly hastate spot or broad streak of black; wing- 

 coverts, m part, colored like back and scapulars but most of them with 

 a large ovoid spot of buff, or ochraceous-buff, on distal portion of 

 outer web; inner secondaries C'tertials") pale brownish gray and 

 buffy, irregularly vermiculated with darker and with an irregular 

 mesial streak of black; remaining secondaries dark sooty grayish 

 brown, rather broadly tipped with ochraceous-buff passing into white 

 terminally (the tips sometimes wholly white on distal secondaries), 

 their outer webs edged, in part, with pale buffy brown or dull ochra- 

 ceous-buff, or sometimes with two transverse series of broken buffy 

 spots on edge of outer web, thek inner webs with a very large trans- 

 verse spot of white entirely across middle portion; primaries dull 

 grayish black passing into hoary gray distally, the four outermost 

 entirely crossed, obliquely, by a broad band of white, this on middle 



« I am unable to give characters by which females of the several forms may be 

 distinguished, the series of specimens being rather meager. Two females from 

 Roraima, British Guiana, are much darker than one from Aunai, in the same country, 

 have the whole of the under parts, posterior to the chest, heavily barred, including 

 the under tail-coverts, and the ochraceous-buff or tawny-ochraceous band across 

 middle of primaries nearly obsolete, the outer webs of the primaries being mostly 

 plain dusky (entirely so in one specimen) ; but one specimen from an unknown locality 

 in British Guiana (possibly from Roraima, however) is precisely similar. Females of 

 5. c. insularis (including those from the coast of Venezuela) and of S. c. alhicauda, 

 also one from Barranquilla, Colombia, are lighter and more buffy in their general 

 tone of coloration, and, besides having a well-defined band of ochraceous-buff across 

 primaries, have the outer webs of the primaries, especially the proximal ones, con- 

 spicuously spotted with the same.
