the stem, which is thus weakened, and presently, 
although both the stem and the ear above are more or 
less stunted, yet the weakened piece of stem cannot ^ 
bear their weight, and it bends sharply down at the 
injured part. Sometimes a gall or some amount of 
swelling of the stem occurs just above where the maggot 
fed, but in the specimens I examined this was rarely 
noticeable. I am told by Mr. John Marten, of Albion, 
Illinois, U. S. A., an economic entomologist who has 
especially made a study of this attack, that the speci¬ 
mens I showed him corresponded in absence of gall with 
the condition of those in Illinois.
