out irregularly, two broods even overlapping, nothing can be done to 
destroy them. All we can do seems to be the rather drastic measure 
of destroying all the leafage in September by means of a strong 
arsenical wash and so killing the larva3 and pupae, or constant 
spraying with paraffin emulsion in the spring to prevent egg-laying. 
The former will of course check to a small extent the growth of the 
tree pro torn. ; the latter is only successful when rains do not come 
and carry away the effects of the wash. 
It is certainly worth while to hand-pick trees that are attacked 
constantly so as to exterminate the moth which may occur under 
certain conditions in dangerous numbers. This is especially to be 
borne in mind by growers, for we can hold out less hope of com- 
bating this insect than the Pear Midge, which still to some extent 
baffles treatment and yet has a distinct period in its existence when 
we should be able to destroy it. 
In examining specimens sent from Huntingdonshire I found many 
of the larvae dead in their galleries. Each of the dead ones had the 
larva (Fig. 4, c) of a Chalcid parasite which had destroyed it. These 
natural enemies unfortunately did not hatch out. 
Caterpillars on Fruit Trees and notes on 
Grease-banding. 
Although caterpillars were not so abundant on fruit trees during 
1903, yet numerous inquiries have been made. Mr. Cecil Hooper, oi 
Swanley, sent a selection of larvae, asking for information, to which 
the following reply was sent : — 
“ The green- and yellow-lined larvae are Winter Moth (C. 
brumata). There were two others in the box : (1) one dull green 
with dark head and the normal number of legs — this is the caterpillar 
of one of the Tortricids — the so-called Allied Bud Moth ( Antithesia 
variegana ) ; (2) the second specimen, reddish in colour, was the larva 
of the destructive Bud Moth {Hedy a ocellana), which, by the bye, 
has not been so harmful this year. There are quite a number of 
Tortricid larvae on fruit trees besides these two you send, but they 
are two of the commonest.” 
Larvae of the Mottled Umber Moth ( Hybernia defoliaricc) have 
also been sent from Sussex. 
Several instances have been recorded of the great benefit derived 
by grease banding for Winter Moth, and where this pest is the chief 
culprit there is not the least doubt that it does an immense lot of
