Taking the apple il was very easy to
pick out the punctsres by aid Of the glass.
A minute. oval puncture. the same being
characterized by a dark. almost black spot,
surrounded by 4 ring Of dark brown.
Remembering that Mr.. Walsh had said that
the eggs were inserted pithia the flesh Of

second report, p. l2i), unless deposited in
worm. holes previously made, for the soft,
blunt ovpositor could not pierce the peel
for that purpose" We asked Prof. Harvey
shout this, and he replied;
The female fly deposits the eggs within
the flesh Of the apple. During my observa
ton st Cumberland | saw more than half
dozen fies in the act Of depositing their
eggs, Watching them carefully with the aid Of
. glass. They never use a worm hole ia
which to deposit the eggs" Prof. Harvey
then explained infinitely the act Of the fe-
male in the use Of the oviposror in puactur-
ing the apple.
The flies are most active" he continued,

There are pair of them-the female being
the larger one. Its wings expand over half

do not know. as the eyes are always bronze
green. The females lay one hundred eggs,
each. think while at Mr.. S~eetser's place
saw as many as forty flies about one tree
and they are not at all difficult to observe"
What is the season Of laying the eggs?'
From about the first of July to probably
through September, or say three months.
There is but one brood year. The eggs
hatch in very few days after being depos-
tied The larve become fully grown during
autumn aud leave the apples through small
circular holes cut in the skin, and enter into
til. ground where they remain until the fol-
lowing July The soil about Cumberland is
very favorable to this insect, it being some
what light and sandy, and the larse burrow
but a very slight distance into the soil to
pass their pupai state"
