 Fig. 168. — Blue -winged YeUow X chrysoptem, and doubtless a hybrid between the two. 

 Warbler. (L. A. Fuertes.) About a dozen specimens known, New Jersey, Connecti- 



cut, etc. A. 0. U. Hypothetical List, 1896, No. 20.

 throat.) White-throated Warbler. Like H. chrysoptem ; but a black bar through eye 

 as in pinus, and lacking the black breast-patch of chrysoptera, the entire under parts being- 

 white ; thus chrysoptera X pinus, and doubtless a hybrid between the two, though up to date

 sylvania, Virginia, Michigan, etc. Figured in colors on pi. 1 of the Nuttall Club Bulletin^ 

 1876. A. 0. U. Hypothetical List, 1896, No. 21.
