COLEOPTERA. 45 



bles also in its form and general appearance. It is of a greenish 

 black color above, with a brassy polish, which is very distinct in 

 the two large transverse impressed spots on each wing-cover ; 

 and the thorax has no smooth elevated lines on it. It measures 

 from four tenths to above half of an inch in length. Its time of 

 appearance is from the end of May to the middle of July, during 

 which it may often be seen, in the middle of 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 (Chrysobothris) fulvoguttata,* 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 trans- 

 verse 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, measuring 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 small and broad beetle having 

 the form of the above, under the name of Buprestis (Chrysoboth- 

 ris) 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 Bupres- 

 tians inhabiting Massachusetts and the other New England States. 



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

 (Trachypteris) Drummondi, in the fourth volume of the " Fauna Boreali- Ameri- 

 cana."
