Petroff (Bull. Soc. Nat. Mosc. xl. 2. pp. 288-293) describes the habits of 
some Mole-Crickets kept by him in confinement. One in the larval state 
passed the whole winter in the ground, in which it made a peculiarly formed 
burrow : in the spring it worked its way to the surface, but died at the end 
of April when moulting. The adult mole-crickets fought whenever they met, 
striking with their fore feet. They would strike in the same way when 
threatened with a stick. One of them was killed and nearly eaten up by 
another. The author fed his- mole-crickets upon ants’ eggs, flies, and the 
larvse of insects, which they ate gveedily, but they would not touch plants 
even when grown from seed for them. 
Cleghorn refers to a large species of Acheta which destroys the young 
Casuarina trees along the Madras railway, by biting off’ their shoots. Trimen 
mentions that Leucodendron argentemn oats the terminal shoots of the silver 
tree at the Cape of Good Hope (Proc. Ent. Soc. Lond. 1868, p. xviii).
