into the soft tissue Of the limb, drains
the life giving sap OF the tree and causes
Its death in from two to three years.
ITS LEE HISTORY.
The mature insect-an oval, yellow.

through the winter and in the spring
gives birth to swarm Of young insects
Uarvae) which scatter and soon insert
their beaks into the woody tissue and
there remain for life, sscreting O waxy
matter which soon forms the scale
which protects them. There are no eggs,
as with most other scale insects, but the
females, as stated. bring forth their
young alive, in rapid succession. from
200 to 500 in O season, and as the larvae
require only about 30 days to reach ma
turity and begin propagating. there
may be five or six successive broods
during the season, and it has been CAL

| REMEDIES.
/. The most effective remedy is FIRE.
Burn every affected tree. That is sur.
