POLYBOEUS LUTOSUS. 



GUADELITPE CARACAEA. 



Polyhorus Lutosus Eidgway, n. s. 



Rah. — Guadelupe Islands, Lower California [E. PalmebJ. 



Sp. ch.— Wing, 15.00-16,40; tail, 10.50-11.65 ; culmen, 1.25-1.35; tarsus 

 3.50-3.'; 5; middle toe, 1.80-2.10. 



Adult. — Pileum, lesser wing-coverts, secondaries, primary-coverts, 

 alula, terminal portion of primaries, entire lining of the wing (including 

 axillars), and terminal band on the tail (1.00-1.60 wide) blackish-brown, 

 sometimes almost black; auriculars, cheeks, and throat dirty whitish 

 or light isabella-color. Eest of the plumage marked with transverse 

 bars of brownish-black or dark brown, and brownish-white or light 

 isabella-color; the bars most regular on the lower surface (and often 

 the npper tail-coverts), where they extend uninterruptedly from the 

 fore neck to the crissum, the bars of the two colors being about equal 

 iu width, the dark ones fainter on the crissum, narrower and more dis- 

 tant on the fore neck ; on the middle and greater wing-coverts, they are 

 similar to those on the abdomen ; on the interscapulars, the dark ones are 

 much wider than the light ones, and nearly black ; on the scapulars, dark 

 brown prevails, the lighter bars being almost obliterated. The basal 

 half or more of the outer five or six primaries are isabella-white, trans- 

 versely mottled, or raggedly barred, with grayish and dusky, the shafts 

 clear yellowish-white. Tail, except dusky terminal band, marked with 

 ragged transverse bars of brownish-gray and isabella-white, of equal 

 widths; the bars of the two colors separated by a narrower zigzag bar of 

 dusky. 



Young. — Remiges and rectrices the same as in the adult, but the 

 terminal baud of the tail narrower and less sharply defined; pileum and 

 lesser wing-coverts dark brown, the feathers with lighter brown edges 

 (these sometimes worn off); back and scapular dull grayish-brown, the 

 latter plain, the former usually slightly variegated with lighter borders 

 and tips to the feathers. Lower parts light grayish-brown, with longi
