INSECTS OF THE FOREST.

chips, in which the grub changes into a chrysalis. It is easy 

 to find a stem of the pine containing a dozen or more of 

 these cells, situated at quite regular intervals under the 

 bark, now loosened or peeling off. If we examine it in the 

 autumn we shall find the grubs, their pupa3, or chrysalides, 

 together with the beetles. The accompanying excellent 

 figures (174) of the pine weevil, its young and chrysalis or 

 pupa, the two latter magnified three times, will give an ex- 

 cellent idea of the different stages of growth of this weevil. 

 The footless grub is white, with a honey-'yellow head. The 

 white pupa has a mummified look, with its eyes partially 

 concealed by its wings, and its legs folded on its breast. In 

 this attitude it lies in its cell or sarcophagus awaiting the

dawn of a new life in the outer world. It either presses out 

 from under the bark and seeks some other hiding place, or 

 lies in its cell until some warm day in April, when with a 

 troop of its fellows it flies about in the sunshine, busied with 

 the care of providing for the continuance of its race. 



Now this work of tunnelling and mining causes the death 

 of the terminal shoot of the young tree. The bush sends 

 out lateral shoots, more or less ci'ooked. One can see plenty 

 of them in the course of any walk in the edges of the 

 woods. Thus deprived of flieir leading shoot such dwarfed 

 and gnarled bushes grow up and vastly injure the appearance 

 of the forest, and its value as lumber.
