roportioned to the rest of the body, so that the classic
denomination, far from giving us any information, might mislead us,
were we to trust it wholly. Nomenclature, which changes from day to day
and becomes more and more cacophonous, is an unsafe guide. Instead of
asking the animal what its name is, let us begin by asking:

"What can you do? What is your business?"

Well, the Microgaster's business is to exploit the Cabbage-caterpillar,
a clearly-defined business, admitting of no possible confusion. Would
we behold her works? In the spring, let us inspect the neighbourhood of
the kitchen-garden. Be our eye never so unobservant, we shall notice
against the walls or on the withered grasses at the foot of the hedges
some very small yellow cocoons, heaped into masses the size of a
hazel-nut.

Beside each group lies a Cabbage-caterpillar, sometimes dying,
sometimes dead, and always presenting a most tattered appearance. These
cocoons are the work of the Microgaster's family, hatched or on the
point of hatching into the perfect stage; the caterpillar is the dish
whereon that family has fed during its larval state. The epithet
glomeratus, which accompanies the name of Microgaster, suggests this
conglomeration of cocoons. Let us collect the clusters as they are,
without seeking to separate them, an operation which would demand both
patience and dexterity, for the cocoons are closely united by the
inextricable tangle of their surface-threads. In May a swarm of pigmies
will sally forth, ready to get to business in the cabbages.

Colloquial language uses the terms Midge and Gnat to describe the tiny
insects which we often see dancing in a ray of sunlight. There is
something of everything in those aerial ballets. It is possible that
the persecutrix of the Cabbage-caterpillar is there, along with many
another; but the name of Midge cannot properly be applied to her. He
who says Midge says Fly, Dipteron, two-winged insect; and our friend
has four wings, one and all adapted for flying. By virtue of this
characteristic and others no less important, she belongs to the order
of Hymenoptera. (This order includes the Ichneumon-flies, of whom the
Microgaster is one.--Translator's Note.) No matter: as our language
possesses no more precise term outside the scientific vocabulary, let
us use the expression Midge, which pretty well conveys the general
idea. Our Midge, the Microgaster, is the size of an average Gnat. She
measures 3 or 4 mi
