44 INSECTS OF MASSACHUSETTS. 



punctures ; the thorax is slightly furrowed in the middle ; the 

 wing-covers are marked with numerous fine irregular impressed 

 lines and small oblong square elevated black spots ; they taper 

 very much behind, and the long and narrow tips are blunt-pointed : 

 the middle of the breast is furrowed ; and the males have a little 

 tooth on the under-side of the shanks of the intermediate legs. 

 They measure from seven to nine tenths of an inch. These 

 beetles may be found sunning themselves upon the limbs of cherry 

 and peach trees during the months of June, July, and August. 



The borer of the hickory has already been described. It is 

 transformed to a beetle which appears to be the Buprestis (Di- 

 cerca) lurida* of Fabricius. It is of a lurid or dull brassy-color 

 above, bright copper beneath, and thickly punctured all over ; 

 there are numerous irregular impressed lines, and several narrow 

 elevated black spots on the wing-covers, the tip of each of which 

 ends with two little points. It measures from about six to eight 

 tenths of an inch in length. This kind of Buprestis appears dur- 

 ing the greater part of the summer on the trunks and limbs of the 

 hickory. 



Buprestis (Chrysobothris) dentipesj of Germar, so named from 

 the little tooth on the under-side of the thick fore-legs, inhabits 

 the trunks of oak-trees. It completes its transformations and 

 comes out of the trees between the end of May and the first of 

 July. It is oblong oval and flattened, of a bronzed brownish or 

 purplish black color above, copper-colored beneath, and rough 

 like shagreen with numerous punctures ; the thorax is not so 

 wide as the hinder part of the body, its hinder margin is hollowed 

 on both sides to receive the rounded base of each wing-cover, and 

 there are two smooth elevated lines on the middle ; on each wing- 

 cover there are three irregular smooth elevated lines, which are 

 divided and interrupted by large thickly punctured impressed 

 spots, two of which are oblique ; the tips are rounded. Length 

 from one half to six tenths of an inch. 



Buprestis ( Chrysobothris) femorata of Fabricius has the first 

 pair of thighs toothed beneath, like the preceding, which it resem- 



* Buprestis obscura, F., found in the Middle and Southern States, closely resem- 

 bles the lurida.
