The history of other insects, erroneously referred to 

 blighting winds, is more easily traced, from their

 this kind. It is well known as furnishing the common 

 poetical comparison of ' a worm i' the bud.' Early 

 in autumn the mother insect deposits an irregularly 

 oval-patch of yellowish eggs, covered with a cement 



Two groups of eggs of the Ros^e leaf roller (Lczctconia Rosa-
