146 INSECTS INJURIOUS TO FOREST AND SHADE TREES. 
2. THE LIBERATED BUPRESTIS. 
Chalcophora liberta Germar. 
Very similar to the Virginian Buprestis, but always smaller sized, measuring from 
0.75 to 0.90 in length, with the second raised line of the wing-covers broader than the 
first or inner line, and totally obliterated where itis crossed by the posterior impressed 
spot, its middle portion between the two impressed spots usually showing a few 
scattered punctures. (Fitch. ) 
This species is much more common in Eastern New York than the 
Virginian Buprestis, the beetle appearing upon the leaves of pines 
throughout the summer and autumn. From a small grove of young 
pines only a few rods in extent, upwards of a hundred specimens were 
taken the middle of last September, one or two being found upon 
almost every tree and bush; whilst only four individuals of the pre- 
ceding and two of the following species were found in company with 
them. They had probably been bred in the numerous stumps of larger 
trees which had been cut down the year before by the side of this grove. 
They stationed themselves at the tips of the limbs, clinging to the leaves 
with their feet, with their heads inwards, their position, shape, and 
size giving them a close resemblance to the young aments or fruit 
cones which were growing from the same points on several of the 
limbs; and they appeared to be eating the young buds, which are prob- 
ably the food on which all these beetles subsist after arriving at their 
perfect state. (Fitch.) This Buprestid is also found in Maine, but 
after several years’ attempts,we have not been able to clear up the 
habits of either species of Chalcophora, or to detect the larvie. 
3. THE OREGON BUPRESTIS. 
Chalcophora angulicollis Leconte. 
A beetle intimately related to the preceding species I met with in a 
collection of insects nade at The Dalles, on Columbia River, many years 
since, by Rev. George Gary, of the Methodist Episcopal Chureh, 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 pernicious to the pine timber of the region where it 
abounds. And as no insect of this genus has hitherto been recorded 
as an inhabitant of that vicinity, that Iam able to discover, I herewith 
submit a short account of its distinctive marks. (Fitch.) 
The beetle 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, 
these widened portions having a few scattered punctures. Both at the apex and the 
base this widened portion is confluent with the irregular elevated stripes which are 
placed upon each side of the middle. The smooth pyramidal spots on the base oppo-
