NOTES AND QUERIES. 
Drirtwoop AND INsect ATTACKS. 
This year our insect visitors have been both numerous and 
varied. 
Hylurgus piniperda has, as usual, come ashore in pretty large 
numbers, As early as 13th March one log had a gallery with 
fifty ova already deposited, but with both parent insects dead 
inside. Not till a month later did any more appear, and then 
three logs arrived, with about fourteen or fifteen galleries each, 
and about fifty eggs in each gallery. At least, I destroyed ova 
and galleries to these numbers, but on visiting the same logs 
about three weeks or so later, I found them quite fully stocked 
with larve, so there must have been some more bore-holes hidden 
in the fissures of the bark which had escaped me at first. This 
time I burned al// the bark, instead of only those parts in the 
immediate vicinity of the galleries. The amount of damage to 
young pine shoots possible by such a swarm is not pleasant to 
contemplate, not to mention the possibility of more deadly attacks 
later on. There were fourteen live insects in the galleries—some 
singly, some in pairs, and some with one dead and one living in 
the boring. These probably owed their preservation to their 
being in the upper end of the gallery when the log was immersed, 
the compression of the air on the ingress of the water preventing 
their being touched by the sea-water. One entrance hole had 
been filled up with sand for quite an inch, and one of the 
imprisoned beetles (both were alive) was actually burrowing its 
way out through it, and had already got about half-way, when I 
found it. 
The next in importance, in point of numbers actually seen, was 
Bostrichus bidens. Of these there have been a good many—so 
many, in fact, that I gave up counting them. They came first 
about the end of July, and afterwards in September. This insect 
seems to have got a hold of the woods in this locality, for I found
