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, 6'. liberta, is quite abundant, as will be seen / 

 when I mention that Mr. Fletcher and Mr. Gresta (a ^^"^ 2i9.-cAaj. 

 former member of this club) collected with me in one ta.—Mar^dei. 

 afternoon (September 21, 1878), in a small grove of sap- 

 lings and young trees, over one hundred 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 an hour twenty-eight 

 (thirteen males and fifteen females) and could easily have obtained 

 more. The larvie 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, i^o. 2.) 



5. The Oregon buprestis. 

 Chalcophora angnlicoUis Le Conte. 



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 

 8ince, 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 smo(^h pyramidal spots on the base oppo- 

 site the middle of the anterior end of each wiug-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
