«The oc{;urrence, as a common sununer resident, of only this form at the locality 

 mentioned, near the eastern border of Illinois, and of only T. a. dedon in Knox 

 County, Indiana, less than forty miles to the eastward, may possibly be explained 

 by tlie positively known fact that both are recent innnigrants, neither having 

 oi'cun\'<l at the places mentioned previt)us to about 1870, Thryomanes beivickii having 

 until then been the only " house wren " of that region. T. a. di'don has come from 

 the east or northeast, and T. a. parkimmni from the west or northwest, until they 

 have practically met (or perhaps by the present time overlajipi'd) in the lower 

 Waljash Valley.
