Fig. 26. — Three lengths of a young deodar sapling infested by Scolytus major, Steb., and 

 S. fninor, Steb. The middle one shows the entrance-holes of female beetles on the 

 bark ; the left-hand one the long vertical zigzag egg-galleries on the sapwood ; and the 

 right the whole sapwood scored by the larval galleries, the shot-holes being the 

 pupating chambers of the grubs. It forms a typical example of the capacity exhibited by 

 this bark beetle for the destruction of young sapling and pole growth. N. W. Himalaya.
