 several insects that are common in other parts of the 

 country than the States for which these reports were

 Society would have similar reports, respecting the insects, 

 peculiar to its state. 



Thus the author found himself compelled to investigate

 considerable efifort; but it brought its own reward in^the

 the garden and orchard, would be a valuable contribution 

 to them, and would constitute a useful portion of the 

 American Pomology he was then preparing. 



Unfortunately for himself, he has discovered that his
