of Tenthredo testudinea upon young apples, devouring the interior of 

 the fruit, being the only instance yet known of such habits amongst 

 the TenthredinidcE, although the larvae of Nematus intercus and some

 emit a verj' powerful scent, similar to that of the bed-bug, and quit 

 the apple as soon as it is fallen to the ground, in order to undergo 

 their transformations in the earth, the eggs being deposited on the 

 young fruit whilst the trees are yet in flower.
