20 RiDGWAY on Birds observed in Knox Co., Indiana. 



heard. I am at a loss to account for the scarcity of this spacies, unless, a 

 be the rarity of sycamore {Pla/anus) trees in the locality under con- 

 sideration. 



Since there is evidently a general misapprehension of the characters 

 distinguishing this race from true D. dominica, it may be as well to state 

 here that the latter is larger, with^a constantly and very decidedly longer 

 bill., while the yellow over the lores is never absent. Var. albilora fre- 

 quently has the yellow over the lores almost as distinct as in typical 

 dominica, but the bill is always much smaller, and somewhat differently 

 shaped. 



PiNE-CREEPiNG Warbler {Dcndfceca pintis). — Rather rare. 



Prairie Warbler {Dendrceca discolor^. — Heard singing among the 

 bushes in an old field on the day of my arrival, and frequently afterward. 



Connecticut Warbler i^Oporomis ag-ilis). — Not uncommon about 

 the middle of May, but very shy. Frequented the borders of the swamp, 

 and escaped into the thick button-bushes when surprised. 



Kentucky Warbler (^Oporomis formosa). — One of the most abun- 

 dant of the summer residents. 



Mourning Warbler {^Geothlypis piiiladelpkia). — Became suddenly 

 very common May 6. Frequented chiefly brush-piles and old fences. 

 Most of the specimens observed were males in fine plumage. 



Black-capped Yellow Warbler {Myiodioctcs pusillns). — Rare 

 during migration. 



Canada Flycatching Warbler {Alyiodiocfes canadensis). — One of 

 the most numerous of the migratory species; first noted April i8, but not 

 common until a week later. 



Hooded Warbler (^Myiodioctcs mitrat/is) .—Rather common in deep 

 woods, but much less so than in the vicinity of the Cypress swamp, 

 further south. 



Solitary Vireo (Lanivireo solitarius). — Rare. 



Cedarbird {Afnpelis cedrorum). — Exceedingly numerous among the 

 willows in the swamp, where feeding upon the larvae of Diabrotica 12- 

 niaciilata infesting these trees. 



Summer Redbird (^Pyranga cestiva). Rather common, but owing to 

 the comparative absence of high, dry woods, much less so than near Mt. 

 Carmel. A female, killed at the same shot with her mate, resembled 

 the male except in the tint of the red, which was of a brick-red rather 

 than vermilion, the male also being in the parti-colored plumage of the 

 immature bird, the red occupying, in both male and female, one-half or 

 more of the plumage. The ovaries of the female were well developed. 



Grass Finch {Pooecetes gramineus') — Common in the meadows, a 

 nest with four eggs being taken April 30. 



Lark Finch {Chondestcs gramniica^. Rather common, chiefly in 

 fields near roadsides. 



White-crowned Sparrow {Zonofric/iia lencop/trys). — Became com- 

 mon about the middle of May. 



White-throated Sparrow {Zonotrickia albicollis). — Very abun- 

 dant up to the middle of May. and a female was started among some bushes
