ANNUAL REPORT OF NEVV-YORK 
PINE. TRUNK. 
Near its middle it was crossed by another perforation extend- 
from the outside directly towards the heart of the tree, which 
is indicated by a black dot in the figure ; and at this point the 
burrow curved slightly outwards towards the exterior surface, 
as represented in the section above the principal figure in the 
cut; and at its end on the left where it passed out of the billet 
of wood it commenced curving inwards towards the heart of the 
tree. Twelve lateral burrows of the same diameter as the trans¬ 
verse one extended upwards and two downwards, as shown in 
the figure, all of the same length, each one having been exca¬ 
vated probably by a single larvae. The gallery of our insect 
thus differs widely from that of the European species (T. eury- 
gaster, Erichson) which mines in the interior of the pine, which 
has no lateral burrows branching off from it. 
The presence of these timber beetles in the wood can be dis¬ 
tinguished from those which mine under the bark, by the littlo 
piles of sawdust which they throw out at the mouth of their bur¬ 
rows, this dust being so much more white and clean, and not com¬ 
posed in part of the brown or rust colored particles of gnawed bark 
which are intermixed with the dust produced by the bark-beetles. 
In addition to the short description of this beetle which is given above, it 
may be observed that the head is finely punctured, the punctures on the face 
giving out small pale yellowish hairs, whilst those on the vertex or crown are 
destitute of hairs, and there is a slight transverse elevation of the surface be¬ 
tween the face and the vertex, from which an elevated smooth line extends 
backwards along the middle of the vertex. Thorax, when viewed from above, 
with its base transverse and rectilinear, its basal angles rectangular, its oppo¬ 
site sides parallel for a distance equalling the length of the base, and from 
thence rounded in a semicircle at its anterior end; its surface anteriorly with 
minute asperities, which, viewed vertically, appear like fine transverse wrinkles; 
its basal half with very minute punctures, and in its centre a small transverse 
tubercle. Wing covers with fine shallow punctures in rows; the upper part 
of the apical declivity moderately depressed in the middle, producing a slight 
concavity in its outline when viewed from above anteriorly, the suture not ele¬ 
vated in this depression, but showing a slightly impressed line along each side; 
the hind end bearded with hairs similar to those upon the front. Under side 
black, the legs and antennae pale dull yellow.
