 without insect remains, whereas 149 contained insect remains, as well as seeds and

 in figures, the insect food constituting a mere fraction of 1 per cent. Of these 149 

 stomachs, 23 contained cotton boll weevil (including two doubtful determinations). 

 One among them contained 2 specimens of a boll weevil and one 3 specimens. In 

 all the stomachs of this bird examined there were found 26 specimens of boll weevil.

 by 10 specimens of this bird. 



Blue-gray gnatcatcher {Polioptila cxrulea), 7 stomachs. — Food consisted exclusively 

 of insects, but all of them of the most minute size. No boll weevils among them, 

 because it is evidently too large an insect. 



White-rumped shrike, ^^ butcher bird'' {Lanius ludovicianus excubitorides) , 7 stom- 

 achs. — All contained insect remains and seeds. One stomach contained 1 boll 

 weevil; another contained 4 specimens of boll weevil.

While it is of little economic importance for these birds, so far as 

 they have insectivorous habits, to eat cotton boll weevils in the fall of 

 the 3^ear when this insect is by far the commonest species to be found 

 in the cotton field, it becomes quite important to tabulate those birds
