A . S. Fuller, liidqewood , i\'. J. — The seven specimens 

 which you gatliered from your apple trees readied us in 

 good condition. They all belong to the above named 

 insect, and its parasites. On p:ige 79, of number 4, 

 you will find a fifture and description of the citer- 

 piUar IVom^hich they were all produced . No. 1 is a

Eggs of the Apple-tree Plant-louse.-J/'. W. Sra- 

 shipman. JIU.— The little oval black eggs that are 



salted so thickly over the biirk of your apple-tree, 

 those of the common Apple-tree Plant-louse (Aphii 

 tl!) . If there should be a warm spell in your neigh- 



borhood early next spring, followed by a frost, most of 

 them will likely enough hatch out and be killed by the 

 frost; for though the eggs can stand almost any degree of 

 cold.tlie young larva cannot. Evenif they all hatch out and 

 survivf, they will be :ittaiked shortly afterwards by so 

 many rMiiiiilial and iiara^itic insects, that they will prob- 

 ably'il" Hci Ml \ niatriial amount of damage. But for
