44 INSECTS INJURIOUS TO VEGETATION. 



the day, resting upon or flying round the trunks of white oak 

 trees, and recently cut timber of the same kind of wood. I 

 have repeatedly taken it upon and under the bark of peach-trees 

 also. The grubs or larva? bore into the trunks of these trees. 



The Buprestis ( Chri/sobofhris)fulvog-itttata* or tawny spotted 

 Buprestis, first described by me in the eighth volume of the 

 "New England Farmer," is proportionally shorter and more 

 convex than the two foregoing species. It is black and bronzed 

 above, and brassy beneath; the thorax is covered with very 

 fine wavy transverse lines, and is sometimes copper-colored; 

 the wing-covers are thickly punctured, and on each there are 

 three small tawny yellow spots, with sometimes an additional 

 one by the side of the first spot ; the tips are rounded, and the 

 fore legs are not toothed. It varies very much in size, measur- 

 ing from about three to four tenths of an inch in length. I 

 have taken this insect from the trunks of the white pine in the 

 month of June, and have seen others that were found in the 

 Oregon Territory. 



Professor Hentz has described a smaU and broad beetle 

 having the form of the above, under the name of Buprestis 

 ( Chrysobothris) Harrisii. It is entirely of a brilliant blue-green 

 color, except the sides of the thorax, and the thighs, which, in 

 the male, are copper-colored. It measures a little more than 

 three tenths of an inch in length. The larvae of this species 

 inhabit the small limbs of the white pine, and young sapling 

 trees of the same kind, upon which I have repeatedly captured 

 the beetles about the middle of June. 



These seven species form but a very small part of the 

 Buprestians inhabiting Massachusetts and the other New 

 England States. My knowledge of the habits of the others 

 is not sufficiently perfect to render it worth while to insert 

 descriptions of them here. The concealed situation of the 

 grubs of these beetles, in the ti'unks and limbs of trees, renders 

 it very difficult to discover and dislodge them. When trees 



* Mr. Kirby has redescribed and figured this insect under the name of 

 Buprestis {Trachi/pteris) Drujumoiuli, i\\ the fourth volume of the "Fauna 

 Boreali- Americana."
