PINE. TRUNK. 
in the inner layers of the bark, and slightly grooving the outer 
surface of the wood; a cylindrical light chestnut red or yel¬ 
lowish fox-colored beetle 0.23 to 0.33 long, bluntly rounded at 
each end, thinly clothed with yellowish hairs, its thorax nar¬ 
rowed anteriorly and with coarseisli shallow punctures, and a 
slightly raised line along the middle, at least on the posterior 
half, a faint blackish line along the middle of the upper part 
of the head, and its wing covers rough, with rather shallow 
furrows in which are coarse indistinct punctures. Appearing 
abroad early in May, numerous in pine forests and in lumber 
and mill yards. Its larvie common under the thick bark of 
pine logs and stumps; a yellowish white footless grub thinly 
clothed with yellowish hairs, and divided into thirteen seg¬ 
ments, its head polished and horny, of a tawny yellow color 
with the mouth black, and the neck having on each side, above, 
a large polished spot tinged with tawny yellow. See Harris’s 
Treatise, page 75. 
Neither the description of Olivier nor that of Dr. Harris clearly 
designates this species, and it is chiefly from its size and its 
commonness that I feel assured this must be the insect to which 
they refer. And I know not what the Hylurgus rufipennis of 
Kirby, which is indicated as being common through New-York 
and British America, can be, unless it is this same species, 
faultily described from discolored specimens. 
248 . Pine Hylastes, Hylastes Pinifex, new species. (Coleoptera. Scoly- 
tidse.) 
A beetle which closely resembles the preceding and is fre¬ 
quently met with in company with it upon pine lumber in mill 
yards early in May, requires to be noticed in this place. I am 
unable to find any description of this species, although it is so 
common it can scarcely have been overlooked by authors till 
this time. It is the Hylastes Pinifex, or the pine-destroying 
Hylastes of my cabinet. Its habits arc doubtless very similar 
to those of the Boring Hylurgas, but the beetle is always 
slightly smaller, measuring 0.20 in length, and is darker colored, 
being deep chestnut red or sometimes black tinged with chest¬ 
nut. It moreover is destitute of the hairiness of that species, 
having only a thin fine short beard on the hind part of its wing
