son of the year. As will have been suggested from the statement 
of the way in which this insect hibernates, it may be very easily^ 
disseminated by means of young apple-trees from nurseries, > either 
in the leaves that remain attached to the tree, or those which oc¬ 
casionally get into the packing boxes. 
PARASITES. 
Mr. Brunn ( l . c.) bred two species of Clialcididae, Sympiezus 
lithocolletidis, Howard MSS. and Astichus tischerice, Howard MSS., 
from the apple Tischeria. We have bred the former of these at 
Champaign, the species having been kindly determined by Mr. 
Howard/ who writes that the descriptions of these species have 
never been published. Mr. Howard has also described' another 
chalcid, Elaswus pullatus, which was supposed to have been bred 
from the apple Tischeria. 
REMEDIES. 
I doubt whether the injuries of this insect in the orchard are 
ever sufficiently serious to repay the labor required foi the appli¬ 
cation of the only remedy for the pest now known,—that ot gath¬ 
ering and burning the fallen leaves; although I believe that this 
operation would pay in the nursery, where the leaves can be easily 
gathered, and several other injurious species would be destroyed 
at the same time.
