Insects, etc.. Injurious to Nuts. 311 



are whitish-grey, the basal patch grey, its outer edge angulated, 

 streaks of grey along the costa, at the hind margin is a large blackish- 

 brown area enclosing a silvery-edged ocellated patch, in which are 

 thi ee or four black longitudinal lines. 



In ten days the eggs hatch and the maggots enter the young fruit. 



The larvib are pinkish-white, with the head and tirst segment 

 brown and are about the size of the Codling jMaggot, l)ut not so fat. 

 Specimens received from foreign Spanish chestnuts were all dirty 

 yellowish-white, one only showing traces of pink. 



They leave the fruit, when mature, by a remarkably small hole, 

 one larva under observation taking half an hour to escape. 



Pupation takes place in the same manner as is done by the 

 Codling Moth. Larv;e occur as late as the 31st of November, and in 

 December in imported nuts. 



Observations made in 1894 showed that they crawl up the 

 walnut trees, spin a dirty white silken cocoon, and pupate in the 

 spring. Morris (3) says they pupate in a brown cocoon in moss. 

 Cocoons are also found in rough grass beneath the trees, and some 

 larvse remain in the nuts all the winter, leaving them in February. 



Should this moth become a serious nuisance in walnuts or chest- 

 niits the banding found so successful for Codling jMotli might be 

 adopted. 



The impoitation of this insect is a matter that must not be 

 forgotten, and is certainly attended with some danger.

THE LEAF BOX BEETLE. 



{Attclahlus cacuHduidcs. Linn.) 



This local yet widely distributed beetle is often very abundant 

 in Europe. It is a weevil, which at times occasions not only much 

 disfigurement to young oak trees, but also attacks the edible or 

 Spanish chestnut in the same way. 



Fisher in Schlich(l) refers to it as locally common on oak and 

 sweet chestnut, chiefly on undergrowth. 



The beetle appears in June. The female cuts and rolls the end 

 of a leaf into a short, stout cylindrical box, which may be doubled
