length, and have a rounded oval head and thorax, with the body 
much more slender, and cover themselves with a dark olive secretion 
that gives them a very slimy slug-like appearance. 
They pupate in the soil beneath the tree when 
full grown, forming a stout chrysalid, the perfect 
saw-flies emerging in about six weeks’ time. 
This is a pest introduced from America, where 
it does a great deal of damage to pear, cherry, and 
other foliage in its larval state. It is also regarded: 
as a very serious pest in Victoria, but in this State 
does not do very much damage, and is easily de- 
stroyed, 
It is very partial to the hawthorn, and when haw- 
thorn hedges exist it spreads rapidly —(Agricul- 
tural Gazette of New South Wales: Froggatt.) ff 
Remedy.—Wait till slugs appear, and then use 
Nos. 11, 12, or 13 (see p. 528). 4 
Dusting the foliage with lime is one of the gypsy 
cheapest and best remedies, as the lime sticks to the (NWN 
slimy coat of the grubs and soon destroys them. XS 
Where they are found to be very destructive to 
the foliage it would be advisable to disturb the soil 
round the trunk of the trees, or treat them with lime, 
so as to destroy the cocoons in the ground.

This remarkable little mite is hardly 
visible to the naked eye, but the galls it pro- 
duces on the under surface of the leaves are 
generally rounded, measuring under one- 
eighth of an inch in diameter, but where the 
foliage is badly infected, coalescing and 
forming a bigger blotch. These galls always 
have an opening about the centre on the 
under side, so that the mites can’escape on 
to the buds before the leaves fall. This is a 
very curious, elongated, cylindrical creature, 
with only two pairs of legs, head tapering in 
front, and transparent in colour. Opinions 
vary as to the amount of damage that this 
mite does to the trees they infest, but there 
is no doubt that they render the leaves very 
unsightly, and by causing them to fall before 
their time denude the tree so that the sun will 
affect it, and when the galls are abundant the 
crop of fruit will be reduced.—( Agricultural
