cocoons of other moths. Fig. 82 shows different colored 
caterpillars, pupa and adult. 
Passing the winter in the pupa state, the cocoons are 
found during the winter principally at the surface of the 
ground, mixed with dirt and rubbish, or in cracks and cre- 
vices of tree-boxes, in fences and under door-steps and base- 
ment walls. The first moths issue from these cocoons in 
May, and deposit their eggs in flat batches onthe under side 
of the leaves. The young worms feed preferably incompany, 
webbing first one and then several leaves together and 
gradually extending their sphere of action until a large part 
of the tree becomes involved. The worms become full grown 
in August. 
ReMeEptIEs:—Trees suffering from the attacks of this-pest 
should be sprayed with London-purple or Paris-green. This 
will not be as‘effective as for most other insects, because the 
worms are protected by a web, which encloses the leaves 
they are feeding upon at the time, but as fresh leaves are 
constantly enclosed by the sheltering web the worms soon 
have to feed upon the poisoned ‘ones and will be killed. If 
the branches are within reach the quickest method is to 
draw the branch through the hand and thuscrush the worms 
and destroy their nest. If the branches carrying the web 
are still small, they may be cut off and thrown on the bare 
ground at a distance from the trees, or the worms may be 
crushed by stepping upon them. A good plan to destroy 
those nests, which are beyond reach of the hand, is to burn 
them with a torch of rags soaked with kerosene. It is even 
possible to destroy the majority of the worms in such a web 
by blowing them into space with a light charge of powder 
ina shot-gun. But whatever remedy is employed, it ought 
to be employed as soon as the nests become visible.
