APPLE. TRUNK. 



this insect, which have not been stated in any of the accounts 

 since published. 



Remedies. — To repel the beetle from depositing its eggs upon 

 the bark, the tree should be rubbed with soft soap or some other 

 alkaline preparation, the latter part of May. Although the insect 

 has been found changed from its pupa to its perfect form in April, 

 I suppose such individuals would remain dormant in their cells 

 until the season became more advanced and warm; and we have 

 no knowledge of its appearing abroad until the beginning of 

 June. We are yet in want of exact observations as to the date of 

 its depositing its eggs. If preventive measures have been neg- 

 lected and these worms have established themselves at the root of 

 the tree, they should immediately be ferreted out and destroyed. 

 This can be done much more easily when they are young and 

 small, as they are then lying directly under the bark. Young 

 trees should therefore be inspected every autumn or early in the 

 spring; and if any particles of powder, like new sawdust, are found 

 upon the ground around the root, the dead blackish bark at that 

 point, and at other places where such bark occurs, sliould be cut 

 away, until the worm beneath is discovered. A little experience 

 wall render one expert in detecting the lurking places of these 

 pests. And they should never be allowed to remain until the 

 second summer, to finish their injury by boring in the solid wood 

 of the tree. 



3. Apple Buprestis, C/iri/so6o;/ins/gmora/a, Fabricius. (Coleoptera Rupres- 

 tidae.) [Plate I, fig 3.] 



A pale yellow footless grub, its anterior end enormously large, 

 round and llattened. Excavating a cavity under the bark and 

 in the solid wood analogous to that of the preceding species, but 

 much smaller. 



The insect a flattish oblong, shining Mack beetle, its under side 

 appearing like burnished copper, its wing covers with three 

 raised lines, the outer two interrupted by two impressed spots. 

 Length 0.50. JJasking in the sunshine, upon apple trees, in June 

 and July. See Trans. N. Y. State Agricultui'al Society, 1854, p.
