PINE. TRUNK. 
the middle of the base of each wing-cover, here has its angles, acute and its 
sides concave, whilst there its angles are blunt and rounded. The sculpture 
of the wing covers presents still more conspicuous differences. In the foregoing 
species a regular furrow or deep groove divides the elevated sutural line from 
the first or inner raised line or rib its whole length, except near the base, 
where, for a short distance, it is narrowed to half its usual width and depth. 
But in the species before us, this furrow at the same point is totally oblitera¬ 
ted, and is but slightly impressed on the anterior half of the wing covers, 
being often replaced by numerous small deep punctures. The elevated line 
on the outer side of this furrow is here marked by a transverse indenta¬ 
tion immediately back of the posterior impressed spot. In the foregoing 
species it is usually the second elevated line of the wing covers which extends 
straight backward from the posterior impressed spot to the tip, the first line 
terminating in this second one at no great distance back of this spot. Here, on 
the other hand, it is the first line which is prolonged to the tip, the second 
one, however, accompanying i,t and being partially blended with it through 
nearly half the distance from the spot to the tip. It is scarcely necessary to 
pursue this subject further, since what has now been adduced will suffice to 
clearly distinguish these species and prevent their being confounded together, 
as they have been hitherto. 
Sisil. Oregon Buprestis, Chalcophora Oregonensis, new species. 
A beetle intimately related to the preceding species I meet 
with in a collection of insects made at the Dalis on Columbia 
river many years since, by Rev. George Gary, of the Methodist 
Episcopal church, and presented to me by the late Dr. Skilton, 
of Troy. Its close relationship to the species above described 
renders it altogether probable that its larva is similarly perni¬ 
cious to the pine timber of the region whore it abounds. And 
as no insect of this genus has hitherto been recorded as an 
inhabitant of that vicinity, that I am able to discover, I here¬ 
with submit a short account of its distinctive marks. 
The Oregon Buprestis slightly exceeds an inch in length, with the elevated 
smooth lines and spots black and for the most part broader than the rough 
intervals between them, which are burnished brassy tinged with coppery red. 
Its sculpture is very similar to that of the species last described above. The 
elevated line on the middle of the thorax is here twice as broad as in that 
species and at each end is rapidly but not abruptly widened to double the 
breadth which it has in the remainder of its length, those widened portions 
having a few scattered punctures. Both at the apex and the base this widened 
portion is continent with the irregular elevated stripes which are placed upon 
each side of tho middle. The smooth pyramidal spots on the baseopposito the 
middle of the anterior end of each wing cover are here larger and more promi 
neut than in either of the foregoing species and each of theso spots has tho
