The whole lining of the wing is barred like the sides. The dark brown prevails on 

 the under surface of the primaries, etc. ; the former having transverse, irregular, ellipti- 

 cal spots of white, these touching neither the shaft nor the edge; on the longest quill are 

 seven of these spots; on all they are anterior to the emargination.

There is only one valid record known to me of the occurrence of 

 this northern species in Illinois, viz., that by Mr. Nelson in his 

 list of the birds of the northeastern portion of the State (Bull. 

 Essex Inst. Vol. VIII., 1876, p. 117), where its capture in Kane 

 county, by Dr. J. W. Velie, the first of September, 1869, is noted.
