 " Selophaga nigricincta, Lafresnate, Rev. Zool. " (Hp.) 



Sp. Cii. — Upper part bluish ash ; a ring around the eye, with a lino running to the nostrils, and the whole under part (except

Length, 5. .34 ; wing, 2.67 ; tail, 2.50. 



Jlab. — Eastern United States to the Mississippi ; south to Guatemala.
