Characters. — Entirely white beneath (except on sides), as in // 

 leucobronchialis, but with black auriculars of H. chrysopti -ra. 



(i) An adult $ ( ?) obtained at Sing Sing, N. Y., July 24, 1SS1, by Dr.

(2) An adult $ (?) obtained at Sing Sing, N. Y., July 24, 1SS1, by Dr. 

 A. K. Fisher. {Cf Fisher, Bull. Nutt. Orn. Club, VI, p. 245.) 



IV. Presumed hybirds between H. chrysoptera and H. pinus 

 (= '//. lazvrencci Herrick'). 



Characters : Black or gray throat and auriculars of chrysoptera. with 

 rest of head and the lower parts yellow, as in pinus; upper parts olive-green 

 as in pinus. Wing-bands yellow or white. 



a. Wing-bands -white. 



(1) The type, an adult J, obtained at Passaic, N. J., May, 1S74, by 

 Harold Herrick. {Cf Herrick, Pr. Phil. Ac. Nat. Sci. 1874, p. 220, pi. 15.) 



(2) An adult $ from Hoboken, N. J., taken in the spring of 1876. 

 {Cf Herrick, Bull. Nutt. Orn. Club, II, p. 19.) 



b. Wing-bands yellozv. 



(3) An adult $ taken at Highland Falls, N. Y., July 7, 1879, by Dr. 

 Edgar A. Mearns (No. 4667, Coll. W. Brewster). This specimen presents 

 nearly the characters that would be looked for in the female of laivrencei; 

 the throat and cheek-markings are those of chrysoptera (female), while 

 the remainder of the plumage is colored nearly as in pinus, the wing- 

 bands, however, are yellow, instead of white, and the back is not purely 

 olive-green." {Cf Brewster, Bull. Nutt. Orn. Club, VI, p. 220.)
