Massachusetts, which is also true of it in this state. That it is one of our 

 commonest species of Aspidiotus on fruit trees is shown by its being 

 the most numerous of those found by Dr Reh on fruit imported into 

 Germany from America {see Bibhography). It has been received frona the 

 following localities, a portion of which were kindly communicated by Dr 

 Howard : Palmyra, Wayne co., Brighton, Monroe co., Medina, Orleans 

 CO., Geneva and Stanley, Ontario co., Waterloo, Seneca co., Ithaca, 

 Tompkins co., Benton, Yates co., Germantown, Columbia co., Ellenville, 

 Ulster CO., Glen Cove, Nassau co., Blauvelt, Rockland co., Flushing, Far 

 Rockaway and Jamaica, Queens co., and Brooklyn. It occurs com- 

 monly about Albany. 



Natural enemies. A minute chalcid parasite, Coccophagus 

 varicornis How., was reared from this species by Prof. Comstock. 



Remedies. This insect can be checked, when necessary, by spray- 

 ing with the insecticides and in the manner recommended for the San 

 Jose scale.
