The Peach-Tree Borer. 



189 



Most of the moths in the above table, except for June 30th, 1899, 

 were reared from borers dug out of peach trees in June. In exam- 

 ining our trees on June 30, 1899, we found that eleven moths had 

 already emerged, some of them possibly a week or more before, so that 

 in exceptional years the moth may appear as early as June 15th in !New 

 York. But our records for the four years preceding 1899 indicate 

 that usually no moths emerge in New York before July 1st, while 

 most of them appear from July 15th to August loth. We have no 

 data as to the emergence of the last stragglers in autumn ; Kellicott 

 (1881) has recorded rearing the moths late in September near Buffalo, 

 N. Y. Thus the time of the emergence of the moths in New York 

 may range from June 15th to nearly Oct. 1st, or over three months. 

 - We have endeavored to compile, in the following table, all of the 

 records which seem to be based on definite knowledge of the time 

 of flight of the moths in different localities or States :
