Hab. — Wooded regions of the Middle and Western Provinces of the United 

 States, and portions of Mexico. 



Ch. SP. — i 9 Gwruleoplumbea, infra alba, crisso rufo-notato,

$ , adult : Upper parts, central tail-feathers and much edging of the 

 wings clear ashy-blue, the whole crown, nape and back of the neck glossy 

 black. Under parts, including sides of the neck and head to above the eyes, 

 dull white, more or less marked on the flauks and crissum with rusty-brown. 

 Wings and their coverts blackish, much edged as already said, aud with an 

 oblique bar of white on the outer webs of the primaries towards their ends ; 

 concealed bases of primaries white ; under wing-coverts mostly blackish; 

 no bold bluish and black variegation of the innermost secondaries. Tail, 

 excepting the two middle feathers, black ; each feather marked with white 

 in increasing amount, the outer web of the lateral feather being mostly 

 white. Bill blackish-plumbeous, pale at the base below, extremely slender. 

 Feet dark brown. Iris browu. Length, 5J-6 inches ; extent, 10^-11 ; wing, 

 3^ ; tail. If ; bill about J of an inch long, but only about f of an inch dee^) 

 at the base.
