NO. 1258. COLLECTION OF HUMMLXGIURDS—OBERHOLSER. 825 
EUGENIA IMPERATRIX Gould. 
Eugenia imperatiix Gould, Proc. Zool. Soc. Lond., 1855, p. 192. 
Ten specimens, from Gualea, west Ecuador. The females are appre- 
ciably smaller than the males, and lack the attenuation of the tail. 
HELIANTHEA LUTETIAE LUTETIAE ( Delattre and Bourcier). 
Trochilus hUe1inDEh\TTB.E and Bourcier, Rev. Zool., 1846, j). 307. 
Hclkmthea lutetiae Boxaparte, Consp. Avium, I, 1850, ]). 74. 
Twenty-seven specimens, from Atcatzo. Quito, and Pichincha. Ecua- 
dor — chiefly from the last-mentioned locality. Judging from this series, 
the innnature females lack the glittering green forehead, though in 
other respects they are similar to the adults. 
We found these birds exceedingly common on Pichincha in Noveml>er, December, 
and January, between 9,000 and 12,000 feet. We never met with them on the 
eastern Andes. Local name, "Ala blanca" — white wings. 
HELIANTHEA LUTETIAE HAMILTONI (Goodfellow). 
HeUanthea hamiltoni Goodfellow, Bull. Brit. Orn. Clulj, X, 1900, Xo. LXIX, p. 
xlviii. 
Fifteen specimens, all from Papallacta, east Ecuador. 
The males difl'er from Ilelianthea lutetiae lutetiae chiefly in the more 
golden shade of the green portions of the plumage, and indicate b}^ 
their individual variation that hamiltoni is but a subspecies of lutetiae^ 
which hitter it represents on the eastern side of the Andes. The same 
difierence in the hue of the green exists in the females, and an addi- 
tional character in this sex of lunnlltenti is the decidedly deeper ochrace- 
ous of the throat. 
In a comnuuiication addressed to the authorities of the United States 
National Museum, Mr. Goodfellow assured them that the type of 
Iltlianthea hamiltoni was among' the examples of this form trans- 
mitted with the rest of the collection. As he failed in the original 
description to designate the specimen, there has been selected as type 
the one which corresponds to the measurements given. This is No. 
173708, U. S. N. M.. and was taken at Papallacta, east Ecuador, iu 
February, 1899. 
We met with this species only on tlie eastern side of the Andes. 
HELIANTHEA TORQUATA ( Boissonneau). 
W' Ornismia torquaia Boissoxxeau, Rev. Zool., 1840, p. 6. 
Bourcieria torquutuK Boxaparte, Consp. Avium, I, 1850, p. 73. 
HeUanthea torqiiata Hartert, Tierreich, IX, 1900, p. 130. 
Ten specimens from Baeza, east Ecuador. These apparently do not 
difl'er from Bogota examples. Young males, almost like the adults in 
other respects, still lack the violet crown patch. 
Found only on the eastern si<le of the eastern Andes.
