FAMILY TROCHILIDAE 341 



inner primary coverts, metallic green, in some with a bronzy sheen ; 

 wings, including outer primary coverts, dull black with a purplish 

 sheen ; central rectrices bronzy metallic green ; outer pairs pure white 

 tipped broadly with greenish black ; f oreneck, breast, sides, and under 

 wing coverts bright metallic green ; a narrow line in center of breast, 

 abdomen, and under tail coverts white; outermost under tail coverts 

 in some spotted with metallic yellowish green. 



Adult female, above like the male, but with the black ends of the 

 outer rectrices tipped narrowly with white ; under surface white, with 

 the sides metallic green ; under wing coverts and a variable amount of 

 spotting on the breast also metallic green, these markings on the 

 throat and foreneck, where present, lesser in size. 



Immature female like adult, but foreneck and upper breast pale 

 gray; green spotting on sides of neck duller, reduced in amount. 



Measurements. — Males (12 from Panama), wing 49.4-52.9 (51.8), 

 tail (26.8-29.0 (27.9), culmen from base 15.9-17.9 (16.6) mm. 



Females (12 from Panama), wing 44.6-48.6 (46.5), tail 24.7-26.7 

 (25.6), culmen from base 15.0-17.7 (16.6) mm. 



Weight, 1 male, 2.93 grams; 1 female, 2.83 grams (Hartman, 

 Auk, 1954, p. 468.) 



Resident. Fairly common in the mountains on the Pacific slope, 

 from the Costa Rican boundary in western Chiriqui through Veraguas 

 to eastern Code (El Valle), at 750 to 1,675 meters elevation. 



The male and female from which this species was named, taken by 

 Warscewicz, are said to have come from "Chiriqui near David, prov- 

 ince of Veragua, at an altitude of from 2000 to 3000 feet," which 

 would place the type locality on the southern base of the Volcan de 

 Chiriqui, near the old trail leading down from modern Boquete. The 

 records do not range above 1,675 meters so that the report of one 

 taken by W. W. Brown, Jr., (Bangs, Proc. New England Zool. Club, 

 vol. 3, 1902, p. 29) at "7,700 feet" (about 2,346 meters) is open to 

 question. The localities of Batty specimens marked from islas Go- 

 bernadora and Cebaco without question are wrongly labeled. Mrs. 

 Davidson secured the species on Cerro Flores, and on the ridge called 

 Chame to the south of it, in eastern Chiriqui. Specimens in the British 

 Museum taken by Arce are labeled from Calovevora, Veraguas. The 

 most eastern record is of a male that I collected March 29, 1951, a 

 little below the summit of Cerro La India Dormida above El Valle, 

 Code. 



I have found these hummingbirds in forest where they fed at 

 flowers in the undergrowth, moving rapidly from blossom to blossom.
