N.B. — Any Agriculturist having memoranda of years when crops 

 have suffered materially from the attacks of this or any of the other 

 noxious insects, would be rendering essential service by transmitting 

 short notices to the Secretary of this Society, in order that the reports 

 may be made as complete as possible, with regard to data, &c.
