I uprooted this pine on 31st December 1897, and carefully- 
dissected all the hark away from the pine which so far had given 
up no beetles. I found near the top of the stem a mature beetle 
in its bed. Lower down the stem I found feeding larvae, i.e., 
larvae which had not yet begun to make a bed, some larger, some 
smaller. 
In the other pine from which the two beetles had issued, I 
found on dissection three pupating larvae in beds below a whorl, 
while below ground I got larvae which had not begun to make 
their beds. 
Pine 19. 
This was a vigorous young pine which held 22 notatus from 
29th May 1897 till 30th June 1897.
