New YorK AGRICULTURAL EXPERIMENT STATION. Zot 
sheltered place in which to form the chrysalis. Often the chry: 
salis will be found on the under side of the leaf upon which the 
caterpillar has been feeding. The adults emerge: in from ten 
days to two weeks. Eggs for the second brood are soon laid. 
The chrysalids of this brood remain until the following spriag 
before the adults appear. 
The caterpillars are seldom sufficiently numerous to cause 
serious injury, but if abundant they are usually held in check 
by jarring from the infested plants or handpicking. Spraying 
with paris green or other arsenical compounds, where prac- 
tical, is an effectual method of destroying them. If paris green 
is to be applied, use one pound to each 150 gallons of water 
with the addition of enough freshly slaked lime to make the 
mixture somewhat milky in appearance. r
