COCCOPSIS CAPITATA (d'Orbigny and Lafrcsnaye)
Tachyphonus caintatus cI'Orbigny and Lafisesnaye, Mag. Zool., 1837, cL
2, p. 29. (Corrientes, Argentina.)
From true Paroaria the group of species included in Coccopsis "*
is distinguished by more slender bill with more strongly curved
culmen, less abrupt defiexure at gape, more exposed nostrils, and
more strongly rounded tail. The present species is easily told from
its congeners by the lack of dark markings on the bill.
The species was first recorded at Las Palmas, Chaco, July 17,
1920. A male was brought to me at the Eiacho Pilaga, Formosa, on
August 8, and at Formosa, Formosa, on August 23, several were seen.
One was noted near Puerto Pinasco, Paraguay, September 3, and at
Kilometer 80 west, where two were prepared as skins, the species
was fairly common from September C to 20. To many this bird
was known as cardenilla from the supposition that it was the female
of Paroaria cristata.
Coccofsis capitata was found usually in pairs in or near thickets,
and fed on the ground in pastures, wet meadows, or the borders of
lagoons. The birds many times were wild and difficult to approach,,
but at Kilometer 80, in IParaguay, came familiarly about the ranch
house. One was observed pulling bits of meat from a bone thrown
out from the kitchen. One that I wounded was seized and carried
away by a small hawk before I could get to it. The call of this
species Avas a low cheio cheio.
An adult female, taken September 16, had the bill apricot orange,
becoming slightly duller at the tip ; iris English red ; tarsus and toes
vinaceous tawny; claws natal brown.

to 19 (immature female, February 19) ; Tunuyan, Mendoza, March
22 to 29. These little birds were found in brush groAvn arroyos, in
open thickets, or in weed patches bordering cultivated fields, often in
mixed parties with other small finches. When excited they came out
on open perches and scolded with jerking tails. At other times they
