the persistent use of Paris green on the first crop while the larves 
are small should be resorted to, even if but few butterflies are to 
be seen. There is nothing more true in the struggle between the 
gardener and the cabbage butterfly than the old adage, ““An ounce 
of prevention is worth a pound of cure,” and the result of neglect 
is a riddled crop of cabbage and a cursing from one’s thrifty 
neighbors. d

THE CABBAGE PLUSIA, OR CABBAGE MOTH. 
Plusia Brassice, Rrey. 
(Ord. Leprpoprera; Fam. Nooruip#.) 
This is a native moth, but is not as well known by gardeners 
as the cabbage butterfly; in fact, the injury which it does to late 
cabbage is usually considered to be the work of the larvee of the 
cabbage butterfly. 
The cabbage moth was first described by Dr. Riley* in 1870. 
Undoubtedly it does more damage to late cabbage and lettuce 
_on Long Island than the cabbage butterfly, as, in this locality, it 
is not checked by parasites. The larva is especially injurious to 
lettuce when the latter is transplanted from cold frames or open 
beds to the forcing-house.
