fklcate outermost feather instead of straight linear parallel- sided rounded-ended ; and under 
parts less glossed with green. The 9 costce lacks green ghjss on under parts, which are 
more white, has much narrower tail-feathers, and is smaller, in comparison with 9 (innce. 
The 9 costcs more closely resembles 9 Stellula calliope, but the latter has traces at least of 
rufous on tail and under parts. Also resembles 9 Trochilus, but has all the lateral tail- 
feathers white-tipped. Arizona and Southern California, and southward. 
139. AT'THIS. (Gr. 'AT^i'y, ^i^/«s, Attic ; also a proper name.) Attic Hummers. Crown of 
not metallic like the gorget, which is prolonged into a ruff ; outer primary of ^ attenuate ; tail 
graduated, the feathers rcnmded at the end, the lateral black-barred and white-tipped in botli 
sexes (peculiar in this respect among N. Am. genera). Bill only about as long as head. Size 
very diminutive. 
416. A. heloi'sae. (Fig. 313.) Heloise Humming-bird. ^: Outer primary attenuate at end, 
with a needle-like point, as in S. platycercus, but not bowed outward. Tail graduated, the 
central feathers, however, sliglitly shorter than the next, all round-ended, none notably nar- 
rowed. No scales on (Town ; 
those of throat produced 
into a ruff. Bill diminutive. 
Above, including crown and 
middle tail-feathers, golden-

Mexico and Arizona. 
140. STEL'LULA. (Lat. stellula, dim. of stella, a star.) Starry Hummers. No scales on crown ; 
those of throat confined to the tips of the lengthened feathers, thus not forming a continuous 
metallic surface, but set like stars in a fleecy, snowy bed. Tail of ^ slightly double-rounded, 
the lateral feathers graduated, the central also shorter than the next ; middle feathers unlike 
back in color ; all broad, and rather widening to near the suddenly contracted ends; outer feather 
slightly incurved, the others ending about as acutely as a silver teaspoon. Outer primary 
simple. Bill longer than head, ordinary, but not entirely black. 9 like ^ in form of tail and 
wings. Size very diminutive.
