PINE BORERS. 683 



covers are brilliant blue, which color is margined on each side and at the base with 

 golden yellow tinged with green, the suture and outer margin being burnished cop- 

 pery red. On each wing-cover are about eight rows of large deep punctures placed 

 closely together, and some of them united or confluent, and between each of these 

 rows is a series of smaller round punctures. Their tips are cut off transversely, and 

 on the side next to the suture is a minute projecting tooth. The scutel is circular, 

 deeply concave, and green, with its sides blue. The thorax is covered with close, 

 deep, coarse punctures, which are more dense and confluent on each side. The head 

 is rough from similar confluent punctures, with a slender, smooth, elevated line in its 

 middle. The antennae are black with the basal joints coppery red. The under side 

 is burnished coppery with the sutures of the abdomen green. (Fitch.) 



12. Spotted-winged buprestis. 



Buprestis lineata Fabricius. 



A shining brassy-black beetle, sometimes blue-black or dark bottle-green, of the 

 same shape with the preceding and .45 to .65 long, each wing-cover with from three 

 to sis pale tawny yellow spots of irregular shape and very variable, the mouth and 

 throat often and sometimes the face of same color, and also a spot on each side of the 

 last segment of the abdomen beneath ; the wing-covers with several impressed lines 

 and a row of punctures on each of the interstices between them, the thorax with 

 coarser close punctures and a single large one on the middle of its hind edge. (Fitch.) 



" I have met with this beetle, in July, on pines growing at a distance 

 from any other trees, an evidence that it had been bred from them. 

 The spots on its wing-covers are extremely variable, being alike in no 

 two specimens. 



" The more usual form is slightly larger, measuring .60 to .75 in length, 

 a;nd the wing-covers with two tawny orange stripes on each, the inner 

 one of which is widest at its base and does not reach to the tip. Here 

 also the last segment of the abdomen beneath has a tawny orange spot 

 on each side, and the throat, mouth, and face, and a stripe on each 

 side of the thorax are yellow, varied in places with red." (Fitch.) It 

 occurs not infrequently in the Middle aud Southern States according 

 to Le Conte. I have found, in company with Mr. Calder, the elytra 

 of this beetle under the bark of the white and pitch pine, in Provi- 

 dence, R. I. 



13. Buprestis macuUventris Say. 



Mr. W. Hague Harrington, of Ottawa, gives the following account of 

 this beetle in the Transactions of the Ottawa Field Naturalists' Club, 

 No. 2, p. 30 : 



Buprestis macnliventris is a brassy-brown species, from five-eighths to six-eighths 

 of an inch long, common upon both old and young trees in June and July. I am 

 inclined to think it feeds also upon spruce, as while in Cape Breton last August I 

 noticed a couple of these beetles in a section wooded almost entirely with spruce, 

 pines being rarely met with. It is easily distinguished by the yellowish-red spots 

 on each side of the segments of the abdomen beneath, and by smaller spots of the 

 same color upon the shoulders of the thorax and upon the face. Its wing-covers are 

 thinner and softer than those of preceding species, and often have a rumpled appear- 

 ance as if bent in two or three places. It is inferior in beauty to our other Bupres- 

 tida). I have found several of the beetles emerging from the pine timbers of the 

 Maria street bridge about the end of June.
