Formosa, August 23 and 24, and Kilometer 80, west of Puerto 

 Pinasco, Paraguay, September 16 (two seen and a female taken). 



Mrs. E. M. B. Naumburg ®^ has recently separated the blue tanager 

 of Bolivia and Argentina (except Misiones) as a race that may be 

 distinguished by darker coloration especially above, somewhat 

 longer wing, and usually smaller bill than tj'pical sayaca from north- 

 eastern Brazil (Bahia and Ceara). Skins from Las Palmas, Chaco, 

 are representative of obscura., while one from Kilometer 80, west of 

 Puerto Pinasco, while intermediate, is so dark that it is best identi- 

 fied with the western race. In the rather limited series that I have 

 seen skins from Matto Grosso, Paraguay, Sao Paulo, and Rio Grande 

 do Sul are distinctly intermediate and appear on the whole nearer 

 ohscura than sayaca. This statement is made with reservation as it 

 is based on a limited number of skins. 



During the winter period these birds were found in bands of three 

 or four to a dozen that worked quickly through the tops of the trees, 

 or that flew with undulating flight for long distances across country. 

 They were shy and difficult to see among the dense leaves of the 

 trees. Little flocks frequented orange trees where they cut open ripe 

 fruit to eat the juicy pulp. 



Hartert is apparently correct in his statement ^^ that there are no 

 Argentine records for T. cyanoptera., as in a fair series of Argentine 

 skins in the United States National Museum that species is not rep- 

 resented. 



STEPHANOPHORUS DIADEMATUS (Temmir.ck) 



Tanagra diademata Temminck, Nouv. Rec. Planch. Col. Ois., vol. 3, livr. 

 41, pi. 243, Dec. 27, 1823. (Brazil.) 



The name Tanagra diademata is ordinarily cited from Mikan's 

 Delectus Florae et Faunae Brasiliensis as "pi. 2, 1820-25." On 

 consulting this rare work it is found that the name in question occurs 

 in the fourth fascicle which did not appear until 1825, so that Tem- 

 minck's publication at the end of 1823 has priority. 



This handsome species was common in Uruguay, where it was 

 noted at La Paloma, the port of Rocha, January 23 (adult and im- 

 mature males taken) ; San Vicente, January 27 to 31 (male and 

 female collected) ; Lazcano, February 6 to 8 (male taken), and Rio 

 Negro, February 15 to 19. The birds inhabited dense thickets. 

 They rested often on the tops of bushes or trees, and when alarmed 

 dropped into heavy cover beneath. They decoyed readily and were 

 collected without difficulty. The song is a pleasant, rapidly uttered 

 warble, finchlike in tone, and the call a soft chewp cheivp. The 

 flight is tilting. Unless light conditions are favorable they appear
