BREWSTER'S WARBLER. 69 



3. Sage, Auk, 1889, 6, p. 279. Portland, Conn., June 13, 1889. Pinus cf 



and chrysoptera 9 engaged in visiting a nest and feeding five young 

 in juvenile plumage. These were all collected. [They will be de- 

 scribed further on.] 



4. Eames, Auk, 1889, 6, p. 307. So. Conn. Leucobronchialis cf and pinus 9 



feeding young, June 24, 1889. The young looked like pinus. 



5. Chapman, Auk, 1892, 9, p. 302. Englewood, N. J. Leucobronchialis 9 , 



washed with yellow below, wing-bars white [i. e. an intermediate between 

 leucobronchialis and pinus] flushed from nest and joined by a typical 

 pinus cf, who shared her anxiety. June 12, 1892. Nest afterward 

 deserted. 



6. Eames, Auk, 1893, 10, p. 89. Bridgeport, Conn., June, 1892. Leuco- 



bronchialis cT with pinus 9 for a mate [no evidence that they were mates 

 adduced, there was a lawrencei d' within a stone's throw]. Nest found. 

 Two young hatched in this nest were like the young of pinus when they 

 left the nest. [Leucobronchialis and pinus look very much alike at the 

 time they leave the nest.] 



7. A. H. Verrill, Auk, 1893, 10, p. 305. New Haven, Conn. Lawrencei 



breeding. Six young in nest, June 5, 1893. [Unfortunately no de- 

 tailed observations are recorded in this case to show clearly whether 

 both parents were lawrencei.] 



8. Sage, Auk, 1895, 12, p. 307-308. Portland, Conn., June, 1894. Leucobron- 



chialis 9 [grading toward pinus] and chrysoptera cf ( cf flew to 9 occa- 

 sionally), nest, and eggs. Both birds, nest and eggs collected. 



9. Bildersee, Bird Lore, 1904, 6, p. 131-132, Beebe, Auk, 1904, 21, p. 387-388. 



Bronx Park, N. Y. Lawrencei cf mated with pinus 9 , nest with six 

 young. [Mr. Beebe says these young in the nest June 13, 1904, were 

 all in the typical nestling plumage of H. pinus. Mr. Bildersee describes 

 them with some detail. On the fourteenth of June they showed traces of 

 yellow on the breast, the jugulum and middle of the belly were bare, 

 the wing-bars white. I do not understand why they were identified as 

 pinus rather than lawrencei.] 



10. Bishop, Auk, 1905, 22, p. 23. New Haven, Conn. Pinus cf nesting with 



chrysoptera 9 , May 23, 1898 {teste A. H. Verrill). [No details.] 



11. Bishop, Auk, 1905, 22, p. 24. Pinus cf mated with 9 intermediate
