BUBONID^ THE OWLS. 415 



GENUS MEGASCOPS KAUP. 



Scops SAVIGN. Desc. de 1'Egypte, 1809, 291. Type, Strix scops LINN. (Nee BEUNN. 1772.) 

 Megascops KAUP, Isis, 1848, 765. Type, Strix asio LINN. 



GEN. CHAE. Small owls with distinct ear-tufts, the tarsus more or less feathered 

 (usually completely feathered) the wings ample (more than twice the length of the short, 

 slightly rounded tail), the plumage exceedingly variegated with vermiculations, cross- 

 bars, and mottlings; toes naked or bristled never completely feathered, except toward 

 the base. 



The above brief diagnosis is sufficient to characterize this group. 

 In general aspect the species of this genus are miniatures of those 

 which belong to the genus Bubo, and are perhaps as nearly related 

 structurally to the latter as to any other members of the family. 



All the American species have the outer webs of the scapulars 

 mostly light-colored (generally white, with a blackish terminal 

 border rusty ochraceous in flammeolus and the darker forms of 

 Irasilianus), producing a more or less distinct stripe along each 

 side of the dorsal region ; the feathers of the upper and lower parts 

 usually have blackish shaft-streaks, those beneath generally with 

 narrow transverse bars; outer webs of the remiges with light- 

 colored spots, and the tail more or less (never sharply) banded. 

 Nearly all the species are, in some part of their range, dichromatic, 

 having a bright rufous phase, quite different from the "normal" 

 grayish plumage.

SP. CHAE. Adult. Ground-color above brownish cinereous, palest on the head, purest

 three lower feathers of the middle and secondary wing-coverts, white, forming (except 

 on the first) conspicuous spots, those of the scapulars bordered with black. Secondaries 

 crossed with about seven regular paler bands, each enclosing a more irregular dusky
