APPLE. TRUNK. 
forations like pin holes appearing, penetrating through the bark 
and into the wood, from each of which comes out a very small, 
cylindrical beetle, which is smooth, slender, black, sometimes dark 
chestnut red, its legs and antenna; testaceous or dull pale yellow¬ 
ish, its thorax anteriorly minutely punctured, the declivity at the 
tip of the wing-covers less abrupt than usual, with an excavation 
or groove along the suture, which gives the apex a notched 
appearance, and near the middle of the declivity upon each side 
of this groove a slightly elevated tubercle of the shape of a cres¬ 
cent, with its concave side towards the suture. Length 0.09. 
I only know this inseet from specimens recently sent me from 
Middlefield, Mass., by Lawrence Smith, Esq., who writes me that 
he took them July 6th, from the trunk of an apple tree ten inches 
in diameter, which was numerously punctured from the surface 
of the ground to where the limbs commenced branching off, above 
which no traces of them were to be found. In another letter he 
st; tes that this insect was first noticed in his neighborhood two 
years ago, when several nursery trees were riddled by them. 
Nothing was seen of them last year; but they have reappeared 
the spring of the present year (1857) in greater abundance, and 
a number of trees have been ruined by them. I find a specimen 
of this same insect also in a collection sent me several years since 
from Ohio, by Dr. Robert H. Mack, of Parma. 
The joints of the feet and the contour of the antenna; is the 
same in this insect as in the genus Tomicus; but between the 
second joint of the antennae and the knob or club is a mere cylin¬ 
drical pedicel to the knob, scarcely as long as the second joint 
and less than half its diameter, destitute of articulations cutting 
it up into small joints. The antennae are thus but five jointed, 
the knob being composed of only three nearly equal joints. And 
I find no genus defined, the antennae of which strictly coincide 
with those of this species. 
Pear blight beetle, Scolytas Pyri. See Pear insects, No. 56. 
Several individuals of this species were also found by Mr. Smith, 
associated with the foregoing, and coming out from the bark a 
few days before them, making a perforation twice as large, the 
holes of that species being but three-hundredths of an inch in
