DENDROICA CORONATA (Linnaeus). 

 SrSmTLE WARBLER. 



Adult male inHprlruj and»Luit.mer. — Above bluish slate-gray, streaked 

 (except sometimes on hindneck) with black, the streaks broadest on 

 back and scapulars; crown with a large, partly concealed, elongated 

 patch of bright lemon yellow, the lower rump with a triangular patch 

 of paler yellow; wings black with gray edgings, the middle and greater 

 coverts rather broadly tipped with white, producing two distinct bands; 

 upper tail-coverts black margined with slate-gray; tail black with gray 

 edgings, the three outermost i-ectrices with a large subterminal patch 

 of white on inner web, decreasing in size from the outermost to the 



' I am unable to define with any degree of accuracy the respective breeding ranges 

 of this form and of D. c. cserulescens in Pennsylvania. Among a large series of spec- 

 imens obtained during the breeding season, belonging to the collection of the Biolog- 

 ical Survey, are some which I can not distinguish from typical D. c. cairnsi (some of 

 them apparently extreme examples, even, of that form) from Cambria, Clarion, Elk, 

 Fayette, Forest, Franklin, Indiana, McKean, Somerset, and Westmoreland counties, 

 four of these counties, namely, Cambria, Clarion, Fayette, and Somerset, being repre- 

 sented by specimens which I am unable to distinguish from typical D. c. cscrvkacm. 

 Breeding specimens from Garrett County, Maryland, vary in much the same way. 

 On the whole, the form is not a very satisfactory one, one of the two characters on 

 which it was based (smaller size) tailing altogether {D. c. cairnsi averaging slightly 

 larger, in fact, than D. c. cserulescens) , and the other only partially so, since many 

 specimens of D. c. cairrm, have little if any black on the back, while many of D. c 

 cserulescens have quite as much as the average amount shown in D. c. cairrm.
