To the inhabitants of New England, and even of 

 the Middle States, the apple-tree is far more useful and 

 important than any, and perhaps all, of the other fruit- 

 bearing plants. This invaluable foreign tree has con- 

 tinued to flourish in despite of the numerous insect 

 foes, that have come with it to claim the rights of natu- 

 ralization, and of those indigenous to the country, 

 which have never ceased to molest it and dispute its 

 claim to the soil. Among the former may be enume- 

 rated several kinds of Aphides, which infest its leaves ; 

 the muscle-shaped bark-louse,* and another species 

 of Coccus,\ of a larger size and broader form, both suf- 

 ficiently described in " The New England Farmer " ; J 

 the caterpillar, that lives beneath the rugged bark of the 

 tree, and is ultimately changed to a moth ; ^ another 

 caterpillar, || called here the apple-worm, that feeds in 

 the centre of the apple and causes it prematurely to 

 fall, an insect well known both in England and France ; 

 the tent-making insect, called here, by way of distinc- 

 tion, the caterpillar^^ which is also an imported spe- 

 cies ; and the misnamed Jlmerican blight, an Jlpkis ** 

 clothed with a cottony fleece, which has been known 

 in this country comparatively but a short time. Not to 

 detain you by any further remarks upon these insects, 

 I will only state, that the apple-ivorm is not, as has 

 been asserted, the young of a curculio, nor of the
