ENEMIES OF THE Locust 
There are at least three different insects which attack the 
to a aaatae the cultivation of the tree entirely without the 
aid of the other two 
The ah ee a the locust borer is a large, beautiful beetle 
nearly an inch in len The beetle is black, with a number o 
appearance. It seems to be a very optimistic insect and may 
often be found gayly flitting about goldenrods and other bright- 
colored flowering plants, where it feeds sparingly on the pollen 
from these flowers. The beetle is short-lived and dies soon after

The hee are about ie diemetee of an ordinary lead-pencil 
and the wood which is chewed up is passed through the body of 
in the form of rather coarse saw-dust-like particles. This par- 
tially digested wood is often thrown out in such large quantities 
as to form little heaps at the base of the tree when badly infected. 
The wood is so thoroughly burrowed in this way that the branches 
are broken off and the whole plantation given the appearance of 
a bullet-riddled forest on a European battlefield 
PossIBLE REMEDIES 
Like all other insects which have resorted to trench warfare 
this borer is very difficult to combat by artificial mean ° 
effective remedy app! le on a large scale has yet been dis- 
covere plication of materials which are so repulsive 
to the insect as to discourage the female from laying her eggs in
