OBSERVATIONS UPON. 
On June 25 the moths were noticed flying 
among the currant and gooseberry bushes where 
they continued plentiful for two or three weeks. 
It was during this period that the eggs were laid, 
and after this neither moths nor worms were seen. 
So these insects are also single brooded 
The ground color of the moth is light yellow, 
and the markings are dark brown. The markings 
vary greatly in different individuals as shown in the 
accompanying drawings.

REMEDIES. 
Kerosene emulsion and insect powder (Buhach) 
were very effectual in ridding the bushes of these 
worms. Paris green or London purple might also 
be used before the fruit has set, but would hardly 
be safe after that. The insect powder may be 
applied in water in the proportion of a tablespoon¬ 
ful to a gallon, or it may be dusted lightly over the 
bushes from a cheese-cloth sack.
