Between it and ll.1:[nus thers are specimens showing every degree of intergradation. Typical exam- ples are comparatively rare, and the most common form has the breast heavily washed with yellow, the back tinged with oli\‘c»grcen, and the white wing— bars washed with yellow: in other words, about intermediate between typ- ical Icttcobz'ouc/t[ti/[s and typical lei/ms.

This hybrid, color phase, or speci s—I do not presume to say what it is, for I think some day we may understand its relationships more. fully—has been found in Louisiana, from Virginia northvard to Con- necticut, and as far west as Michigan. Its breeding ‘ange appar- ently coincides with that of II. pinus. Upward of one hundred speci- mens, representing typical letteribl'onchfall's and 'arious phases of its intergradation with pines are known. and in the Connecticut River Valley the bird is stated to be more frequent than 11. chrgsoptera.
