moths, and Pyrales, or Pearls, which are easily frightened, the
females of which will rush from their places of concealment even
before they are prepared to start on the mission of ovipositing. The
converse of this rule, that female insects captured on the wing are
almost invariably impregnated, may be taken as an axiom, at least so
far as the moth tribe is concerned.

Of course females which have made their appearance in our breeding
cages are the most eligible for the purpose of attraction; but
whenever we breed these with the intention of using them for
attracting, we must bear well in mind that the rearing process,
whether from the chrysalis, the caterpillar, or the egg, must be
conducted under surrounding conditions of temperature, etc, as nearly
as possible resembling those to which they would be subjected in their
natural state. Otherwise, if we retard their appearance by keeping our
breeding-cages in too cool a situation, we shall be too late for our
sport, or at best capture only worn specimens; while, if we force them
by an unnatural state of warmth, the males will not have made their
appearance at large by the time we are ready to arrive upon the
hunting-ground.

Having furnished ourselves with a bred female, the next procedure will
be to construct a cage for her reception in such a manner that the
males will be compelled to keep within a respectful distance, and
formed of such material as will permit the air to readily permeate the
sides of the prison.

Fig. 55--Assembling cage.

The cage (Fig. 55) adapted to our requirements is a very simple
affair; it is formed by bending our three strips of cane of about
equal lengths each into the form of a circle, and fixing them in that
form by means of twine; these three circular pieces are then placed in
such a manner that they cross one another at right angles (Fig. 55),
thereby forming the rudimentary outline of a hollow sphere, over which
it is an easy matter to stretch and tie a piece of leno. When required
for use the female may be put in, either loose or clinging to a twig
of the length of the diameter of the globe, and the leno tied
afterwards.

"The theory of the peculiar action of the female upon the senses of
the males is usually considered to be due to a subtle scent which
emanates from her, and is wafted on the breeze to distant parts; and
it is believed that by means of this scented track the males are
enabled to discover the whereabouts of the o
