OF INJUKIOUS INSECTS.

the trees to he often husliy headed, and when the tree is thus affected 
it retards it in growth and reduces its ultimate value. When young 
Fir plantations are thinned all the brush ought to be at once removed 
or burnt on the ground, as this Beetle propagates in the decaying 
branches in legions. They ascend the standing trees, and commit 
extensive ravages. When Fir thinnings are carted from the plantation 
it is a very common practice to dress the bark off to lighten the 
carriage in transit to market. The dressing off of the bark should not 
be permitted within the plantation; in a year after, the ground round 
these heaps of bark may be seen covered with grown shoots blown 
from the growing trees, bored by the Beetles which the heaps have 
nurtured. 
With the above observations many other notes have been 
contributed, of which some are of considerable interest generally, but 
not being with regard to injurious insects are not available here. I 
have also been favoured with a few notea giving a general sketch of 
amount of insect presence in the Isle of Jersey, and round Denbigh, 
North Wales; and a few observations of injurious insects not noted 
iu the list, which I now give, as well as some words regarding Culias 
Edusa , which, though not injurious, was included in our first Report, 
as possibly throwing some light on similar occasional appearances of 
other species. Through the hands of Mrs. Tourel, Les Pres, Jersey, 
I have a note of the spring and summer having been there (as 
elsewhere) unusually wet and cold, and insect presence less than 
usual. 
Cockchafers have been little seen; and Black Aphis on the Beans, 
Green Aphis on the Roses, and American blight, have been less 
prevalent than usual.
