50 COLEOPTERA. 



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 im- 

 pressed spots, two of which are oblique ; the tips are round- 

 ed. Length from one half to six tenths of an inch. 



Buprestis ( (Jfirysobothris) femorata (Fig. 25) of Fabricius 

 Fig. 25. has the first pair of thighs toothed beneath, like- 

 the preceding, which it resembles 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 larvae 

 bore into the trunks of these trees. 



The Buprestis (Chrysoboihris) fulvoguttata* (Fig. 26), or 

 Fig 26. tawny-spotted Buprestis, first described by me in 

 the eighth volume of the " New England Farm- 

 er," 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 some- 



* Mr. Kirby has re-described and figured this insect under the name of Biipreitis 

 ( Trachypterit) Di-vmmondi, in the fourth volume of the " Fauna Boreali-Ameri- 

 cana." 7 



[ ' Buprettis ( Chrysobothris) ftdvorjuttnta does not belong to Ckryiobc&nt but to 

 Melanophila, Esch. The anterior thighs are not armed with a tooth, and the base 

 of the thorax is truncate. LEC.]
