28 APPLE-TRUNK BUPRESTIS TREES IT INHABITS. 



and on each side of each segment is an irregular triangular indentation, from 

 the inner angle of which a faint impressed line extends inwards. On each side, 

 beneath, is an impressed, longitudinal line. There are no conical projecting 

 points at the apex of the last segments. 



These borers, sent to me as above stated, have not yet completed 

 their transformations; but they will in all probability remain in 

 their present cells in the wood, and be changed to pupse the com- 

 ing spring, from which the perfect insects will issue the latter 

 part of May and during the month of June. And there can be 

 little doubt that they will prove to be the species named by Fa- 

 bricius Buprestisfemorata, which species pertains to the modern 

 genus Chrysobothris . This insect may be met with in all parts of 

 our country. The natural place for its larva is in the White oak, 

 and it is probable that being deprived of a sufficient supply of 

 this wood, in which to deposit its eggs, in consequence of our 

 forests being so rapidly and extensively cut down, this insect has 

 been obliged to resort to the Apple and Peach trees. Dr. Harris 

 speaks of meeting with it upon and under the bark of Peach 

 trees, and I have captured it upon the Apple tree. Professor 

 Kirtland, of Cleveland, Ohio, doubtless alludes to this species, 

 (Downing's Horticulturist, vol. ii. p. 544,) when he says, "Our 

 Apple trees are often injured by the larvae of the Buprestis, which 

 will girdle out extensive portions of the bark and young wood." 

 This, moreover, is in all probability the beetle of which a wood 

 cut illustration is given in the Ohio Cultivator, vol. x, page 242. 

 Although no description of the insect or its larvse is given, the 

 figure presents more points of resemblance to C.femoruta than to 

 any other common American species. The following interesting 

 particulars, there stated, sufficiently indicate that this beetle will 

 be liable to do great damage in our orchards. The editor says, 

 " The late Dr. Barker of McConnellsville, (Morgan county, Ohio,) 

 called our attention to the injury done to his Apple trees, by the 

 beetle represented above, several years ago. It was in the month 

 of July, and large numbers of these beetles were seen running up 

 and down the trunks and branches of the trees, while beneath 

 the bark extensive ravages of .the larvae were found. We ob- 

 served, however, that these injuries seemed in nearly or quite all 

 cases to have commenced where the bark had previously been
