362 SHRIEKIXG BIRDS— STRISORES. 



Female. Outer primary not attenuated ; colors similar to male, wanting the metallic 

 gorget ; the feathers spotted with dusky ; crissum and flanks more rufous ; innermost tail 

 feathers entirely green ; other feathers as in male, but with the central black encroaching 

 on the basal rufous ; third and fourth feathers tipjied with reddish-white. 



Hub. Southern New Mexico to Guatemala. 



The introduction of this .sf)ecies into the fauna of the United States is 

 based on a female sjoecinien collected by Mr. J. H. Clark at El Paso, Texas, 

 and tor a time supposed to be Sdasjfhorm ru/us, but, after a careful exam- 

 ination by j\lr. Lawrence, has been pronounced to lielong to this species. 

 Its range is southward along the lughlands of INIexico to Guatemala. 



The species is very much like Sdaaphorvs in shape, and hardly differs 

 more than S. ru/us and 2^^((t!/<'crcus do from each other. The male is easily 

 distinguislied from its allies ; the females are closely related to those of 

 ru/us, difl'ering in much shorter bill (0.4.5 to 0.6.5), much less rufous on the 

 more nearly even tail, with broader feathers, etc. 



Genus STELLULA, Gould. 



Sirlluh, Gould, Introd. Trochil. 1861, 90. (Tyfic, Trochilus ealliope, Gould.) 



Gen. Char. Bill rather longer than the head, straight ; wings much developed, reach- 

 ing beyond the tail, which is short, nearly even or slightlv rounded ; and with the inner- 

 most feathers abruptly shorter ; the outer leather rather narrower and more linear than 



the others. Metallic throat feathers elongated and rather linear and loose, not forming a 

 continuous metallic surface. Central tail feathers without green. 



This genus established liy Gould has a .slight resemblance to AffJiis, but 

 differs in absence of the attenuated tip of outer primaiy. The outer three 

 tail feathers are longest and nearly even (the second rather longest), the 

 fourth and fifth equal and abruptly a little shorter ; the latter without any 

 green. The feathers are rather broad (the outermost least so), and are ob- 

 tusely rounded at end. Tlie tail of the female is quite similar. The ab-
