very regular wide bars of brown ; lining of the wing dusky, spotted with 
rusty. Wing, 16.50 ; tail, 9.50. 
In the coloration of its lower parts, this example calls to mind 
certain specimens of Pernis apivorus which we remember to have 
seen. A somewhat similar individual is represented in the lower 
figure of Plate XXXII of Naumann’s Vogel DeuUchlands.

ADDITIONS TO THE AVI-FAUNA OF ILLINOIS, WITH 
NOTES ON OTHER SPECIES OF ILLINOIS BIRDS. 
BY E. W. NELSON. 
Since the publication of Mr. R. Ridgway’s “ Catalogue of the 
Birds ascertained to occur in Illinois,” * several species not named 
therein have been taken in the State, and many interesting notes 
respecting other little-known species have been gathered. Only the 
most important of the latter will be noticed in the present paper.
