366 ANNUAL REPORT OF NEW-YORK 



CHERRT. TRUNK. 



S. THE CHERRY. — Cerasus vxdgaris^ et al. 



Though some of the insects noticed below have only been 

 observed upon our wild cherries, Cerasus serotina and Virginiana^ 

 there is little doubt but tlie same will at times invade the garden 

 cherry; and all the trees of this genus are so closely related to 

 each other that, for a purpose like the present, it appears unne- 

 cessary to divide them into different heads. 



AFFECTING THE TRUNK AND LIMBS. 



T 1. DiYAEiCATED BupRESTis, Dicerca divaricata, Say. (Coleoptera. Bupres- 

 tidse.) 



A flattened worm resembling a tadpole and otherwise similar to the 

 Apple BuprestiSj No. 3; mining in the sap wood under the bark; the 

 perfect insect appearing the last of June and through July, run- 

 ning up and down the trunk of the tree in the sunshine ; a thickly 

 punctured snapping beetle, having a coppery lustre, its wing covers 

 striated and freckled with small blackish spots, their ends narrowed, 

 drawn out and spreading slightly apart, the tips blunt and as 

 though broken off. Length 0.70 to 0.90. The beech is undoubt- 

 edly the original residence of this insect, and wherever a dead 

 tree of this kind occurs some of these beetles will almost always 

 be found upon it on sunny days in midsummer. I know not why, 

 in the lately published Catalogue of F. E. Melsheimer, Kirby's 

 generic name Stenwis is preferred to that of Eschscholtz, whilst 

 on a following page precedence is given to one of the generic 

 names of the latter author over one proposed by Mr. Kirby. As 

 Eschscholtz's names for these genera were published several years 

 anterior to those of Kirby I have retained them. For some fur- 

 ther items respecting this insect see Harris's Treatise, p. 42. 



The Rough Osmoderma No. 7, and the Horn-bug No. 6, occur 

 in their larva state in old decaying cherry trees, and in their dead 

 stumps one or both of these grubs will be found in profusion and 

 of all sizes.
