upon the tree, spinning their cocoons in this case in the barrel cr e 
or in any suitable dark niche or cranny at hand.- After spinning it 
cocoon if does not immediately transform to pupa, but remains in 
_ the larval state within the cocoon until nearly spring, and in this — 
inclosed hibernating condition it is by no means passively dormant, 
as Professor Riley ‘observed duri ing the winter of 1867—68 that each. 
time he cut open a cocoon to observe the condition of the larva it 
fastened up the incision. 
An apparent exception to the rule that the insect hibernates as a 
larva was observed on certain specimens received at the Department 
November 15, 1883, from Mr. M. B. Newman, of Wyandotte, Kans., 
and which were already in the pupa state on receipt, and in fact 
when sent (November 12). From these pupze, which were kept in 
a comparatively warm room, two moths issued January 8, 1884, and | 
two more January 14. The same gentleman stated, on the authority 
of Mr. R. B. Armstrong and other orchardists near Wyandotte, that 
large numbers of dead Codling Moth larvee were found under the 
loose bark of the apple trees during Octover, and which had doubtless 
been killed by the cold drenching ¢ rains which prevailed at. that 
time. We were unable to secure specimens for identification, how-| 
ever, and the statement must remain unverified. 
The cocoons of this brood are often found between the staves ae 
hubs of apple barrels. Hundreds can be sometimes found in such 
locations. 
It may be of interest to state that i in North Germany, where the - 
insect is single-brooded, the moths make their appearance and de- 
posit their eggs from the middle of June on into J uly. A 
FOOD PLANTS. 
Although the Codling Moth is above all an apple pest, it is quite a 
general feeder, and is found in other seed fruits of the same family, 
such as pears and haws. The stone fruits of the family Rosacez are 
less infested than the others, although it is sometimes found quite 
abundantly in peaches, and instances are on record showing that it 
does considerable damage to plums in some localities. Apricots are 
also infested. It has also been found in Europe in all of these fruits. 
Outside of the fruits of the family Rosacee, however, it is not known 
in this country. 
There are, however, several European records of the occurrence of 
this insect in walnuts and oak-galls to which we may properly give. 
some consideration. The first of these records appears in a paper by 
Laboulbéne in the Annales de la Societé Entomologique de France, 
5th series, Vol. I, 1871, page 295, from which we translate the follow- ; 
ing paragraphs: 
*'The shell of the nuts deprived of the green envelope shows often 
at the point of attachment a blackish hole. The two halves separated 
show the kernel gnawed and a great quantity of brownish grains: 
made by the excrement of a larva, Moreover, the substance of the 
nut or the kernel has in places a dark tint, and occasionally the ae 
sue has been spoiled, shriveled, or covered with mold. Finally, in 
several fruits I have noticed on careful examination silk threads 
among the brownish excrementai pellets.
