leaves of the cabbages were literally riddled with holes, more 
than half their substance being 
eaten away. And at almost every 
step, numbers of the little moths 
which hatch from these worms 
would arise upon the wing and 
flit away a few yards, to some 
covert. Fortunately, it is only 
the free outer leaves of the cab¬ 
bage which are preyed upon by 
this worm, whilst the compacted 
inner leaves, forming the head, 
on which the value of this vegetable depends, are left uninjured. 
But there is no doubt the eating away of the outer leaves, to such 
an extent as is frequently done by this worm, weakens and stints 
the growth of the head, which, it is well known, continues to 
advance in size until the very end of the season. And among 
those varieties of the cabbage which do not form large and com¬ 
pact heads, such as the Savoy and broccoli, this moth must be 
utterly ruinous. Even if it did no direct injury to the vegetable, 
the presence of these little green worms, in such numbers upon 
the leaves, wriggling about so spitefully when disturbed, is quite 
annoying; and the eroded leaves mar the tidy appearance of the 
garden. 
It is a little remarkable that this species occurs in all its states 
so late in the autumn as the middle of October, as the several 
British moths which are co-generic with it all make their appear¬ 
ance in July and August. It is hence altogether probable that 
there are two generations of the moth iu each year; and if so, the 
first generation will make its appearance, it is quite likely in the 
month of June, or at all events before the heads have begun to 
form and when all the leaves are young, open, and adapted.for 
its resort. It will consequently be liable, then, to do great 
injury to this vegetable. 
This worm, in its appearance, motions and habits, has a.close 
resemblance to the Palmer worm which has recently stripped 
the foliage from our orchards and forests so extensively, aud to
