PIONEA FORFICALIS (Garden Pebble Moth). An 
insect living, in the larval state, on the leaves of Cabbages 
and Horse-radish, as well as on Hedge Mustard and 
other uncultivated Crucifere. The moth is common 
throughout the country. It is a little over lin. in spread 
of wings. The front wings are rather pointed at the tip, 
and in colour are dull straw-yellow, shaded with pale 
brown; a brown line runs from the tip to the middle of 
the inner margin, and another nearly parallel to it, but 
paler brown, crosses the middle of the wing, widening 
towards the front margin into a dark, ill-defined spot. 
There are also one or two other less distinct lines, run- 
ning in the same general directions with these. The 
body is pale, shining straw-yellow in colonr, as are also 
the hind wings, which have a brown marginal line, and 
a brown line running parallel with it. The larva has six 
true legs and ten prolegs; it is yellowish-green, with a 
darker green line down the middle of the back, and one 
along each side, bordered above with a white line. The 
head is brown. There are usually two broods in the year. 
Some moths emerge in May. ‘They lay eggs, and from 
these emerge larvw, which feed on the plants named 
above, usually between the leaves, under protection of a 
thin web of threads. They turn, in the soil, into pup», 
from which moths emerge about August. These produce 
a new brood of larvæ, which feed up in autumn, to become 
moths in the following May. The damage done by the 
moths is seldom serious, though the larve are tronble- 
some in often being boiled between the leaves of Cabbages 
and served at table. The only practicable remedies are 
picking off the larvæ and catching and killing the moths. 
PIONY. See Peonia. 
PIOPHILA APII (Celery-stem Fly). A fly which 
has been described by Professor Westwood, in the 
“ Gardeners’ Chronicle,” as injurious to Celery. The 
yellowish - white maggots burrow, during winter and 
spring, in the stems, eating their way upwards, and 
leaving burrows of a rusty-red colour in the tissues. 
They are blunt behind, but taper in front, and have tw» 
black hooks in the front end. The maggots change into
