same point, September 21 (female). In Chaco and Formosa the bird
was common. It was a ground-haunting species that ranged with
other small birds in the undergrowth of forests, or, in morning
and evening, ventured out into the more open cover of scattered
bushes at the borders of the savannas. The birds were curious and
were readily enticed to view from dense coverts. The striking jet-
black males, that occasionally showed a flash of white from the
shoulder in flight, seemed more shy than the cinnamon-colored
females.
In a male taken July 9 the maxilla and tip of the mandible were
black ; base of mandible pale neutral gray ; iris dull brown ; tarsus
brownish black; underside of toes washed with yellow-

Brazil."")
An adult male was taken at Kilometer 25, west of Puerto Pinasco,
Paraguay, September 1, 1920, and a female on the Cerro Lorito, on
the eastern bank of the Rio Paraguay, opposite Puerto Pinasco, on
September 30. These two agree in appearance with skins from
Matto Grosso and Rio de Janeiro. Male specimens from southern
Paraguay (Sapucay), representing H. g. fosteri Sharpe, have the
rump and breast slightly darker, but only one has the broadened
yellow markings on the superciliary and forehead supposed to dis-
tinguish this form. This subspecies is apparently poorly marked.
Though the generic term Hernithrawpis is here used for this
tanager, I see little save diiference in color pattern to differentiate
it from Nemosia of Vieillot.
These birds frequented the tops of tall trees in heavy forest. They
were observed gathering nesting material September 30. The female
had the maxilla and tip of mandible blackish brown number
3; rest of mandible cinnamon buff; iris bone brown; tarsus deep
green-blue gray.

This tanager was fairly common in forested areas. It was observed
at Resistencia, Chaco, Jul}^ 8 and 10, 1920; Las Palmas,
Chaco, July 30 and 31; Riacho Pilaga, Formosa, August 18; Formosa,
Formosa, August 24; Kilometer 200, west of Puerto Pinasco,
Paraguay, September 25 ; and Tapia, Tucuman, April 9, 1921. The
four skins preserved include male and female from Resistencia, July
8 and 10
; female from the Laguna Wall, 200 kilometers west of Puerto
