faleate outermost feather instead of straight linear parallel-sided rounded-ended ; and under 
parts less glossed with green. The 9? coste lacks green gloss on under parts, which are 
more white, has much narrower tail-feathers, and is smaller, in comparison with Q apne. 
The Q cost@ more closely resembles 9 Stellwla cailiope, but the latter has traces at least of 
rufous on tail and under parts. Also resembles 9 Yrochilus, but has all the lateral tai.

with a needle-like point, as in 9. platycercus, but not bowed outward. Tail graduated, the 
central feathers, however, slightly shorter than the next, all round-ended, none notably nar- 
rowed. No scales on crown;

lilac. Under parts snowy-white, glossed with golden-green, touched with rufous on flanks. 
Very small: length 2.75; wing 1.25; tail 0.75; bill 0.50. 9: No peculiarity of outer

Mexico and Arizona. 
STEL/LULA. (Lat. stellula, dim. of stella, astar.) Starry Hummers. No scales on crown ; 
those of throat confined to the tips of the lengthened feathers, thus not forming a continuous 
metallic surface, hut 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 oputenblel ends; outer feather 
slightly incurved, the others ending about as acutely as a silver teaspoon. Juter primary
