her
nut trees. Then, too, the leopard moth, _zeuzera pyrina_ Linn., and the
carpenter worm, _Prionoxystus robiniae_ Peck, may be found occasionally
in most any kind of tree.

The chestnut tree (if it has thus far escaped the blight or bark
disease) may show small, deep tunnels into the wood of trunk and
branch, made by the chestnut timber worm, _Lymexylon sericeum_ Harr.
Slow-growing woodland trees are more apt to show these galleries than
trees of rapid growth standing in the open.

There are a number of tussock moths, sawflies, beetles, etc., which feed
on the leaves of nut trees. Spraying with lead arsenate will prevent
damage. There are also many sucking insects attacking them, such as the
hickory gall aphis, and several species found on the leaves. Some of
these may be controlled by spraying with a contact insecticide such as
nicotine solution or kerosene emulsion.

In the Southern States, pecan trees are attached by some of these
insects which I have mentioned; there are also many more which cannot
even be mentioned in the time allotted to this paper. Information may be
obtained regarding them, by any one interested, and for this purpose I
have appended a short list of publications.

A MEMBER: Early in the spring I noticed something on the
hickory trees swollen and bright red in color, so that the trees were
conspicuous from a distance. Later insects emerged which appeared to be
these little gnats that fly in swarms.
