rface, and changes into the pupa
state. The pupa is three-fourths of an inch long, and of a mahogany
brown color. The perfect moth appears about the first of September,
and there is only one brood in a season.

The caterpillars feed in the stalks of corn, tomatoes, potatoes,
dahlias, asters, and also in young currant bushes, besides feeding on
many species of weeds. By a close inspection of the plants about the
beginning of July, the spot where the borer entered, which is
generally quite a distance from the ground, may be detected, and the
caterpillar cut out without injury to the plant. This plan is
impracticable for an extensive crop, but by destroying the borers
found in the vines that wilt suddenly, one can lessen the number
another year.

THE PYRAMIDAL GRAPEVINE CATERPILLAR.

_Pyrophila pyramidoides_ (Guen.)

This caterpillar, Fig. 21, is generally found on grapevines early in
June, but also feeds on apple, plum, raspberry, maple, poplar, etc. It
is about an inch and a half in length, with the body tapering toward
the head; of a whitish green color, darker on the sides; with a
longitudinal white stripe on the back, broader on the last segments.
Low down on each side is a bright yellow stripe, between this and the
one on the back is another less distinct, and the under surface of the
body is pale green.

[Illustration: FIG. 21.]

The caterpillar is fully grown about the middle or last of June, when
it descends to the ground, draws together some of the fallen leaves,
and makes a cocoon, in which it soon changes to a mahogany brown pupa.

[Illustration: FIG. 22.]

In the latter part of July the perfect moth, Fig. 22, emerges,
measuring, when its wings are expanded, about one and three-fourths
inches; the fore wings are dark brown shaded with lighter, with dots
and wavy lines of dull white. The hind wings are reddish, or of a
bright copper color, shading to brown on the outer angle of the front
edge of the wing, and paler toward the hinder and inner angle.

The under surface of the wings is lighter than the upper, and the body
is dark brown, with its posterior portion banded with lines of a paler
hue.

This pest may be destroyed by hand picking, or by jarring the trees or
vines on which they are feeding, when they will fall to the ground and
may be crushed or burned.

THE GRAPE BERRY MOTH.

_Eudemis botrana_ (S.V.)

The moths emerge and fly early in June, and are qu
