298 BULLETIN 133, UNITED STATES NATIONAL MUSEUM TAENIOPTERA CINEREA CINEREA (Vieillot) Tyrannus cinerciis Vieillot, Anal. Nouv. Ornith. El^m., 1816, p. 68. (Argen- tina.'^) Examination of the type and three other specimens of T. c. ohscura Cory^® indicates that this form is sli^jhtly darker than true cinerea. This flycatcher was recorded at the following points : Las Palmas, Chaco, July 13 to August 1; Riacho Pilaga, Formosa, August 8 to 21 ; Puerto Pinasco, Paraguay, September 3 ; Kilometer 80, west of Puerto Pinasco, September 8; San Vicente, Uruguay, January 26 to February 2; Lazcano, Uruguay, February 3 to 9 (noted on February 9 as far as Corrales). Three adult males taken at Las Palmas, Chaco, July 28, Riacho Pilaga, Formosa, August 8 and San Vicente, Uruguay, January 26 were preserved as skins. The series of this species at hand is far from adequate for comparison, but it may be noted that a female from Matto Grosso appears paler above and has a broader light tip on the tail than the specimens listed above. The two skins from Las Palmas and Formosa are in full winter plumage. The one from Uruguay is in very worn breeding feather, but has not yet begun the molt. The iris is martius yellow, lined heavily toward the inner margin with peach red, so that at casual inspection it appears wholly red; bill and tarsus dull black. The present species ranges through the warmer areas of the region visited, as none were seen in the pampas of Buenos Aires. It is an inhabitant of open country, but chooses localities where trees or bushes are not far distant. The birds were encountered frequently about houses, or in the outskirts of little towns, or were observed in numbers along roads that wound through the open country. They chose commanding perches on posts, tops of bushes, telegraph wires, or, failing these, on elevated clods or little eminences on the ground, where they rested with heads drawn down in usual flycatcher attitude in watch for prey. When food was sighted they darted down to the ground to seize it, alighted perhaps to run along for a few steps, and then returned to a higher perch. Their wings were long and pointed and their flight, accompanied by a flashing of the black and white wing markings, light and graceful. As they alight the wings are often raised above the back for a second until they gain a secure hold on the perch. They are alert, active, and graceful in all their movements.

BIRDS OP ARGENTINA, PARAGUAY, URUGUAY, AND CHILE 299 wing, and short tail are observed. During sharp, frosty winter mornings in the Chaco, as the first rays of the sun stretched with pleasing warmth across the open prairies, these flycatchers often uttered a little whistled song that could undoubtedely be readily set to the scales used in human music by one versed in musical anno- tation. In Uruguay they were especially common along the country roads, seeming in hot weather more sluggish than during the winter season. In the warmer part of the day they chose perches on fence wires, where their heads were in the shadow of a post. At rest they were so inconspicuous as to be often overlooked. Near San Vicente they were common in an extensive forest of palms where they appeared to be nesting, though no nests were found. In the summer time I heard them utter a faint swee.

Two were secured at Victorica, Pampa, on December 26, 1920, an adult male in worn breeding plumage, and another preserved in alco- hol. The birds were encountered on this date in fair numbers scattered through rolling pampa, where low bushes or small trees were spread at intervals. They rested in the tops of bushes or occasionally among open limbs in a tree, at intervals jerking the tail. The flight was slow and direct and was performed with rapid beats of the partly opened wings. The birds were silent. The adult male taken had the bill and tarsus black; iris natal brown. TAENIOPTERA IRUPERO (Vieillot) Tyrannus Irupero Vieillot, Tabl. Enc. Meth. Orn., vol. 2, 1823, p. 856., (Paraguay.) Though Hudson has recorded this flycatcher as common through- out the Argentina of his time, the species now seems restricted in its range, as I did not find it in the open pampas. It was noted at the following points: Los Amores, Santa Fe, to Charadrai, Chaco, July 5, 1920 (seen from train at frequent intervals) ; Resistencia, Chaco, July 9; Las Palmas, Chaco, July 13 to August 1; Riacho Pilaga, Formosa, August 8, 14, and 21 ; Formosa, Formosa, August 23 and 24; Puerto Pinasco, Paraguay, September 1 and 3; Kilometer 80, west of Puerto Pinasco, September 6 to 21 ; Victorica, PamjDa, December 23 to 29 ; San Vicente, Uruguay, January 25 to February 2, 1921; Lazcano, Uruguay, February 3 to 9; Modesto Acuiia, Cor- doba, March 31 (seen from train) ; Tapia, Tucuman, April T to 13.
