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. 



PAEASITES. 



Mr. Brunn (I. c.) bred two species of Chalcididse, Sympiezus 

 IHJiocolleiidis, Howard MSS. and Astidh/tis 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. 



EEMEDIES. 



I doubt whether the injuries of this insect in the orchard are 

 ever sufficiently serious to repay the labor required for the appli- 

 cation of the only remedy for the pest now known, — that of 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.
