LEAF WEEVILS. 145 



take to wing, and consequently avoid the tarred cloth held 

 beneath." A few days later — on June 4th — Mr. Eayfield 

 reported that the beetles appeared to be diminishing in 

 number, but, though he searched carefully, he could not 

 make out where the eggs were laid, or the maggots lived. 



This matter would be well worth investigating where attack 

 is prevalent, and, by turning up sods in different places under 

 some of the trees that were infested last year, there would be 

 a good chance of finding the maggots. They might be ex- 

 pected to be whitish and legless, with a head furnished with 

 jaws, and in general appearance, although much smaller, very 

 like Otiorhynclius maggots (for reference, see Index). 



For means of prevention and remedy, see p. 143. 



Obseevation. — Like Apple and Plum, the Pear is subject 

 to a great number of insect attacks common to other orchard 

 trees, besides those which are mentioned in the foregoing 

 pages as more especially infestations of its own. 



Amongst these may be mentioned, amongst Pear attacks, 

 infestations of the Great Tortoiseshell Butterfly, Codlin Moth, 

 Goat Moth, Lackey Moth, Mottled Umber and Winter Moths, 

 the Wrinkled Bark Beetle {Scohjtus rugulosus), the Apple- 

 blossom Weevil, and a black weevil (Otiorhynchus tenehricosus, 

 Herbst) which attacks leafage, the very common Cherry and 

 Pear Sawfly and the Apple-blossom Sawfly, the Apple Aphis 

 and the American Blight Aphis, and also the Mussel Scale. 



As mentioned at p. 48 and in the Preface, it has been 

 endeavoured, so far as was conveniently practicable, to give 

 the infestations affecting several kinds of trees under the 

 name of the tree, of attacks to which, observations were 

 especially contributed ; but in the alphabetical list of orchard 

 trees, and fruit bushes, which precedes the Index at the end 

 of this volume, the names of the infestations affecting each 

 will be found enumerated. — E. A. 0.
