246 Gooseberry Grub. 
those near the lower part of the stem, which are their most 
favourite resort; and as soon as he sees a small perforation, 
at first scarcely bigger than a pin’s head, let him diligently 
examine the tree, and carefully remove every infected leat No 
labour will be better repaid than this. I have usually turned 
in a troop of little boys, who can easily insinuate their fingers 
amongst the branches ; and, with a little practice, they become 
expert in plucking the ege-bearing leaves, for which they are 
paid at a certain rate per hundred; collecting them in a bas- 
ket, the contents of which should be burnt or scalded, so as 
to prevent the escape of a single grub, Another remedy might 
be resorted to in gardens much infected with this nuisance ; 
namely, taking the trees carefully up, and transplanting them 
in new ground ver vy early in the spring; and then soaking the 
holes from which they were taken with quicklime and scald- 
ing water ; though, such is the impenetrable case of the cocoon 
in which the chrysalis is enshrined, that I have my doubts 
whether this precaution, however severe, will in all cases 
answer. It might be supposed that, by carefully examining 
the soil, great numbers might be taken: but this is not the 
case ; fa whether from a glutinous quality in the external shell 
of the cocoon, or other cause, I know not, minute particles of 
earth adhere to it in so singular a manner, that I found it 
almost impossible to discover a single individual in the earth 
of a small flower-pot, in which, to my 
certain knowledge, a considerable num- 
ber had buried themselves; and from 
W hich, i in fact, after I had searched in 
vain, when their hour of release was at 
hand, they emerged in full force. I 
have aude a drawa ing of the insect : one 
with its wings spread; the other, as it 
usually rests when alighting on a leaf. 
( fig. 43.) The dark spot upon the 
upper wing is an infallible mark where- 
by to distinguish them from some 
other small ichneunion flies resembling 
them, at least not easily distinguished 
by persons who are not naturalists. 
The under side of the leaf is given for 
the purpose of showing the mode in 
which the eggs are arranged like neck- 
laces of small pellucid beads. The 
Linnean name of the insect is the 7en- 
thrédo cdpreee. (See Turton’s Linneus, vol. iil. p, 418.)
