203 THK NUT CULTUKIST. 



nuts on the very largest trees in the forest and elsewhere, 

 I cannot suggest any other remedy than to gather the 

 immature and infested nuts as they fall, and bum them, 

 with their contents. 



Among the larger Lepidoptera (butterflies and 

 moths) there are many species, the caterpillars of which 

 occasionally feed on the leaves of the hickoi'ies, but not 

 exclusively ; consequently, they cannot be considered as 

 the special enemies of this genus of trees. When they' 

 do attack them, it is as much due to accident as design. 

 This is certainly true with the great Luna moth (Attacus 

 luna) and the American silk worm {Telea polyphemus), 

 and various species of the Catocala, as well as the Tent 

 caterpillar (CUsiocampa sylvatica). 



There is also a hickory-nut weevil, closely allied to 

 the species infesting the chestnut ; and while not quite 

 as large, its habits are similar, and its ravages may be 

 cheeked by the same or similar means. The grubs bore 

 into the green nuts, causing some to fall before half- 

 grown ; others may remain in the nuts until they are 

 ripe and gathered in the autumn ; consequently, per- 

 forated hickory nuts are not at all rare, even on the 

 stands of venders in our cities. 



Bud worms, leaf miners, leaf rollers and plant lice, 

 — and among the latter several gall-making species, — are 

 to be found on the hickories ; but with all these natural 

 enemies to cofitend with, the hickories thrive, grow, and 

 yield their fruits in greater or less abundance. To enu- 

 merate, describe and illustrate all the insects known to 

 be enemies of the hickory would require a large volume, 

 but fortunately there are many special works published 

 on the insects injurious to vegetation, and these are 

 readily obtainable by all who may have occasion to con- 

 sult their pages.
