The Bulletin 
about tlie time tbe corn is sprouting. At this time the seed leaf is 
vigorous and green and the unfolding leaves (bud) are withered and 
dead in those stalks that have been attacked by the root-worm. (Big. 9.) 
On the other hand, in stalks attacked by the corn bill bugs all the leaves 
remain fresh and green at this time and later the whole plant dies if it 
is severely attacked. These young stalks usually show the character¬ 
istic rows of holes acoss the leaves. (Big. 10.)
