PINE BORERS. 679 
specimens being found of all shades from brassy black or purple to 
orange bronze. This beetle, like the preceding one, is frequently found 
(especially upon saplings) in the center of a cluster of leaves, head 
inwards, and in this position would, by the inexperienced 
observer, be probably taken for a young cone. It appears 
to feed upon young cones and leaves at such times, and 
these are probably the food of all the pine-investing Bu- 
prestians after reaching the perfect state, as I have found 
nearly all the species thus situated in the leaf clusters. 
This beetle, C. liberta, is quite abundant, as will be seen / 5* 
when I mention that Mr. Fletcher and Mr. Gresta (a FlG - ^.-ohau 
cophora liber- 
former member of this club) collected with me in one to ._ Marx del. 
afternoon (September 21, 1878), in a small grove of sap- 
lings and young trees, over one huudred specimens, and that a couple 
of days afterwards we collected in the same place over half as many. 
On the 23d September, 1880, I captured in about au hour twenty-eight 
(thirteen males and fifteen females) and could easily have obtained 
more. The larvae of these beetles had probably bred in trees, or 
stumps and logs in the neighborhood, and had resorted to these sap- 
lings to feed and pair." (W. Hague Harrington in Trans. Ottawa Field 
Naturalists' Club, No. 2.)

A beetle intimately related to the preceding species I met with in a 
collection of insects, made at The Dalles, 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 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 I am 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 aud 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- 
site the middle of the anterior end of each wing-cover are here larger and more promi- 
nent than in either of the foregoing species and each of these spots has the shape of 
a right-angled triangle, the line bounding its outer side running directly forward 
instead of obliquely inward and forward, each spot being also more broad than long. 
The rough depression which extends forward from these spots to the anterior angles
