20 Ridgway on Birds observed in Knox Co ., Indiana. 
heard. I am at a loss to account for the scarcity of this species, unless n 
be the rarity of sycamore ( Platanus ) 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 ( Dendroeca Pinas'). — Rather rare. 
Prairie Warbler {Dendroeca discolor). — Heard singing among the 
bushes in an old field on the day of my arrival, and frequently afterward. 
Connecticut Warbler ( Oporornis agilis). — 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 ( Oporornis formosa). — One of the most abun- 
dant of the summer residents. 
Mourning Warbler (Geotklypis Philadelphia). —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 ( Myiodioctes pusillus). — Rare 
during migration. 
Canada Flycatching Warbler (Myiodioctes canadensis). — One of 
the most numerous of the migratory species; first noted April 18, but not 
common until a week later. 
Hooded Warbler (Myiodioctes mitratus). — Rather common in deep 
woods, but much less so than in the yicinity of the Cypress swamp, 
further south. 
Solitary Vireo (Lanivireo solitaries). — Rare. 
Cedarbird (Ampelis cedrorum). — Exceedingly numerous among the 
willows in the swamp, where feeding upon the larvse of Diabrotica 12- 
maculata 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 (Pocecetes gramineus) — Common in the meadows, a 
nest with four eggs being taken April 30. 
Lark Finch (Chondestes grammica). Rather common, chiefly in 
fields near roadsides. 
White-crowned Sparrow (Zonotrichia leucophrys). — Became com- 
mon about the middle of May. 
White-throated Sparrow (Zonotrichia albicollis). — Very abun- 
dant up to the middle of May, and a female was started among some bushes
