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 pupse, 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 crooked. One can see plenty 
of them in the course of any walk in the edges of the 
woods. Thus deprived of their leading shoot such dwarfed 
and gnarled bushes grow up and vastly injure the appearance 
of the forest, and its value as lumber.
