OBSERVATIONS UPON 
on the ventral surface. The wings are clear at 
their bases but are scaled along their anterior 
and outer margins, and have a black patch of 
scales about two-thirds of the distance from the 
base to the tip. The posterior wings have scales 
along their outer and posterior margins only. The 
female moths lay little, brown, almost globular, 
eggs, one in a place, on the stems of the bushes. 
From these eggs the little larvae hatch and eat 
their way to the pith of the stem, up and down 
which they burrow until fully grown, which is early 
in May. The larva when about fully grown eats a 
hole out to the surface of the stem, through which the 
moth may afterwards escape. The winter is spent 
in the stems in the larval state. During the 
following May the larvae change to pupae in the 
stems and from these pupae the moths begin to 
appear about the ioth of June. 
REMEDIES. 
The best remedy for this insect is to cut out 
all infected stems early in the spring and burn 
them. The bored stems can usually be detected 
by the little holes that the larvae have eaten to the 
surface for the escape of the moths. 
When the moths are abundant about the 
bushes a great many of them can be taken in nets 
and destroyed, and much of the egg-laying pre¬ 
vented.
