bugs, also eat large numbers of the eggs of the moth, andsome 
true bugs, as the spined soldier-bugs, kill many caterpillars 
while they move about to enter the cob or when they leave. 
Turkeys and chickens, if they have the run of the corn-fields, 
are also very beneficial and should be permitted to range in 
fields known to be infested with insects of this kind. Our 
numerous shrews also do good service against such insects and 
should not be killed, simply because they look like mice. 
REMEDIES. 
Every caterpillar thatis found in an ear of corn when pre- 
paring itfor the table should be killed and not simply thrown 
with the leaves forming the husk upon the rubbish heap, as in 
such a case they will simply crawl to some other plant. Many 
remedies have been proposed but none seem to be of much 
value for this insect. A systematic rotation of cropsis claimed 
to keep them in check. Late plowing is also considered a good 
remedy, as the pupe hidden in the soil are exposed to the in- 
clemencies of winter. Simple freezing, however, causes but 
little injury to any hibernating insects,and only repeated freez- 
ing and thawing is destructive to them. Such remedies may 
be of great value in the southern states, but as the moths issue 
here in October, it is more than doubtful whether any pupze 
hibernate at all in our state. It is very likely that all tassel- 
worms, whether they are larva, pupze or moths, die in early 
winter, and that the worms found during the month of Septem- 
ber in the ears of corn are produced from moths which immi- 
grated north from the southern states in which they always 
occur. | 
THE ROSIN WEED CATERPILLAR. 
(Heliothis phlogophagus G. & R.) 
Another species of Heliothis was, a few years ago, very 
common near the Experiment Station, but instead of causing 
injury, it assisted us very materially to check abad weed. The 
rosin-weed (Grindelia squarosa Dunal) is a western plant, 
which had found a lodgement along the railroad tracks and 
near by. Here it rapidly increased, and would have scattered 
far and near if unexpected assistance had not arrived. The 
plants grew very vigorously and produced immense numbers 
of beautiful golden flowers; they also produced lots of seeds,
