"Medellin." Doubtless the last-named locality may be understood to indi- 

 cate high mountains near Medellin. 



Our specimens agree minutely in color with four males from Cuzco, Peru, 

 but are smaller. 



Cuzco, 3 males average, wing, 68-73; tail, 59-62; culmen, 11-12 mm. 



Paramillo, 5 males average, wing, 64-67.5; tail, 57-60; culmen, 11-12 

 mm. 



Paramillo (12,500 ft.) 19. 



(4036) Diglossa lafresnayei {Boiss.). 



Undrostrum lafresnayei Borss., Rev. Zool., 1840, p. 4 (Bogota). 



Not uncommon in the Temperate Zone of the Central and Eastern Andes. 

 Almaguer, 2; Laguneta, 1; Santa Isabel, 1; Chipaque, 4; Choachi, 3. 



(4037) Diglossa humeralis (Fraser). 



Agrilorhinus humeralis Fraser, P. Z. S., 1840, p. 22 (Bogotd). 

 Diglossa humeralis Wyatt, Ibis, 1871, p. 324 (high regions near Bucaramanga ; 

 9000 ft.). 



Found by us only in the Temperate Zone of the Eastern Andes. At 

 Chipaque both this species and D. lafresnayei were common, their occur- 

 rence together affording an interesting illustration of how two species, 

 which differ from each other, less than do many subspecies, may be found 

 at the same place. 



Chipaque, 4; Subia, 3; La Mar, 1; Palo Hueco, 1; La Pradera, 3.
