changed to a dull yellowish spongy substance resembling dried 
apple, with deep fissures or sinuses running through it. The 
seeds were blackened but entire and perfect, one only being worm 
eaten. In the centre was a large irregular cavity or vacant 
space, the sides of which were wet and slimy, and with numer¬ 
ous black grains, the castings of the worms which had occupied 
this cavity. And adhering to this slimy matter were found two 
pup® of a small fly or midge, with numerous empty shells or 
skins of other pup® from which the flies had hatched. And the 
remains of some of these flies were also present, having perished 
from their wings becoming entangled in this slimy matter. But 
they had mostly disappeared, the hole perforated by the codling 
worm giving them a passage way out to the external air. And 
it hence appears probable that it is those apples only, which are 
thus perforated, which are resorted to by these insects, as the 
passage which may be seen leading from the flower end into this 
cavity is scarcely of sufficient size to give them an exit after 
they have completed their transformations. 
A fly was also discovered, which had that moment left its pupa 
shell, its wings being then undeveloped and only a third the 
length of its body. But in less than half a minute they had ex¬ 
panded to a length equalling that of the body, in which state 
they remained, the dry atmosphere let into the apple by cutting 
it asunder rendering them rigid and incapable of expanding to 
their full size. This fact beautifully illustrates how extremely 
delicate the wings of these flies are, requiring the damp atmos¬ 
phere which they find in the interior of the apple to keep them 
soft and pliant until they become fully developed; and if a 
breath of dry air passes over them at this time, it dries them pre¬ 
maturely and they thenceforth remain deformed. 
Whether the parent fly places her eggs upon the flower end of 
the apple and the young worms mine their way from thence into 
its center, or whether she attacks those apples only which the 
codling worm has left, crawling into the fruit through the per¬ 
foration in the side which this worm has made, future researches 
must determine. The latter, however, appears to be the most 
probable. And this insect would hence appear to merely con¬ 
tinue the mischief which the codling moth has commenced. The
