THE LUTESCENT WARBLER. 173 



MOST Alaskan species, even of those which retire in winter to South 

 CaroHna, Florida, and the Antilles, may ' be expected to drift thru our 

 borders sooner or later. Typical H. cclata was first caught in the act by 

 Mr. Bowles in May, 1907, but we have no means of knowing that th'e 

 northern form is not a frequent trespasser. Kermode gives it as a common 

 summer resident east and west of the Cascades in British Columbia, and it 

 is not impossible that our northern Cascade records should be referred to 

 this type.
