HICKORY. TRUNK. 
12. THE HICKORY.— Carya alba et al. 
The several species of hickory and walnut are all preyed upon 
alike by the same insects with a very few exceptions, and these 
trees suifer much more from their attacks than any of our other 
wild fruit trees. In the state of New-York are upwards of sixty 
insect depredators belonging to these trees. Only a part of these, 
however, are yet known to us in their perfect state so that we are 
able to name and describe them. 
AFFECTING THE TRUNK AND LIMBS. 
151 . Tiger Cerambyx, Goes tigrina, Dcgeer. (Coleoptcra. Cerambycidse.) 
Boring large holes lengthwise in the solid wood, a large cream- 
yellow grub, slightly tapering, with a faint darker line along the 
middle of its back, a black head chestnut-brown at its base, and 
the first ring flattened and pale tawny yellowish; changing to a 
pupa in the burrow it excavates (as do all other borers of the 
beetle kind), and producing a long-horned beetle of a brown 
color covered with incumbent short tawny gray pubescence, more 
dense on the wing covers, which have a broad dark brown band 
beyond their middle and another on their base, the thorax with 
an erect blunt spine on each side, and the antennae pale yellowish 
with their first joint dark brown. Length about one inch. This 
is the common borer in all the hickory and walnut trees in my 
neighborhood. Those species of the old genus Monohammus, in 
which the feelers are blunt instead of pointed at their ends, have 
recently been set off' into a distinct genus by Dr. Leconte, to 
which the name Goes is given. See Transactions, 1854, p. 850. 
The annexed cut handsomely illustrates the principal opera¬ 
tions of this insect; and those of the Apple-tree borer and other 
large borers belonging to the family Cerambycidae are closely 
analogous to this. On the left hand side of the figure near its 
lower end is seen a small cavity which the parent beetle gnaws 
through the hard dead outer layers of the bark, and a small perfo¬ 
ration through the soft new inner layers. Does the parent drop her 
egg in the bottom of the cavity which she gnaws, and does the 
young worm eat its way through the soft inner layers to the
