BIRD LIFE IN THE URUBAMBA VALLEY OF PERU. 115 



(4041a) DIGLOSSA PERSONATA MELANOPIS Tschudi. 



Diglossa m-elanopis Tschudi, Wiegm. Arch., 1844, p. 294 (Peru). 

 Diglossa personata Authoks (Peruvian and Bolivian records). 



Comparison of 4 specimens from Peru and 16 from Bolivia, with 

 a very large series from Colombia, shows that this southern form, 

 heretofore synonymized with true personata, may be recognized by its 

 generally duller bluer color, especially on the wings, and by the 

 absence of the conspicuous whitish edgings on the lower tail coverts 

 present in all our adult Colombian examples. 



As in Colombia, the species in Peru appears to range from the 

 upper part of the Subtropical to the Temperate Zone. 



Above Machu Picchu (12,000 feet), 1 male; Torontoy, 9,500 feet, 

 1 female; 14,000 feet, 1 male; Occobamba Valley, 9,100 feet, 1 

 male. 



(4042) DIGLOSSA INDIGOTICA Sclater. 



Diglossa indigotica Sclater, Ann. Mag. Nat. Hist., 1856, p. 467 (Ecuador). 



This species appears not to have been recorded from Peru^ but the 

 specimen listed below, together with 9 from Inca !Mine, agree with 

 one labeled as coming from Ecuador. 



Rio San Miguel, 4,500 feet, 1 male (breeding, Oct. 5).

A species of the Temperate Zone which is unknown between south- 

 ern Peru and central Ecuador. An even more striking hiatus occurs 

 in the recorded range of Diglossa hrunneiventris which is unknown 

 between central Peru and northern Colombia. Such gaps in distri- 

 bution indicate lack of continuity in the Temperate Zone itself, and 

 when the species found in these Temperate Zone islands show no 

 appreciable differentiation, it seems evident that they have become 

 isolated at a comparatively recent date. Specimens of Dif/lossa 

 hrunneiventris from Colombia, for example, are inseparable from 

 others from Peru, and it now appears that the bird described by me 

 as Oreomcnes hingliami is but the immature plumage of Oreomanes 

 fraseri, Doctor Hellmayr writes me that an immature specimen in 

 the collection of the Munich Museum is molting from the plumage 

 of ''hingliami" to that oi fraseri. The chin and malar stripe are 

 white, but the superciliaries have acquired, through molt, the chestnut 

 color of those of the adult. 



Cedrobamba, 1 female.
