harder leaves. 
The insect, like several other members of this sub-family, is 
said to drop to the ground the moment the leaf on which it is 
feeding is touched, and Mr. Rogers noticed that it was then, 
owing to its colouring, very difficult to see amongst the dead 
leaves and decaying vegetation. 
Protection and Remedies. 
In the nursery the Paris-green treatment should prove suffi- 
cient to stop this insect’s attacks, since it is a foliage-eater in 
its adult stage. Other treatment will, however, be required for 
the larva should it make its appearance, The life history re- 
quires working out. 
Points in the life history requiring further observation. 
1. Where the eggs are laid. 
2. When and where the larve hatch out and feed and 
| the nature of their food. 
3. The length of time passed in the pupal stage. 
4, The number of generations in the year.
