Emerging- flics in the field were often observed in the 

 toils — a single ant, at this time, being able to hold a flv, and 

 tlie cane is always swarming with them. 



The larvae of the flies only escape because the parasitized 

 borers plug the channels behind them and build ant-proof co- 

 coons, for the ants quickly destroy both grubs and maggots 

 when exposed.

The author reports Pheidole megacephala as giving much 

 trouble to householders, attacking foods, but states that this 

 species is more of a garden pest. He says that they fre- 

 quently loosen the soil around young plants, causing them to 

 fall over, and that they are more troublesome in dry situa- 

 tions. 



Control measures include placing the legs of tables, etc., 

 in dishes of water, or tying bands soaked in ant-poison about 

 the legs, and the destruction of the nests. Since this species 

 nests in the soil, outside of the building, they are easily killed 

 l)y the use of gasoline or carbon bisulphide.

This interesting note follows : 



"Toward the last week of July, 1912, all over the Goondi, 

 Darradgee and Mundoo cane plantations near Innisfail, I saw 

 little heaps of dead ants, each heap containing several hun- 

 dred specimens of the workers and soldiers. They were rather 

 common and I was considerably puzzled to account for them 

 until chancing to hear from a farmer that young sugar cane 

 had l)een slightly damaged by recent frosts; the ants doubtless 

 had suffered from the same cause, the more clearly indicated 

 because the species appears to be an equatorial one or one of 

 the uplands or of situations not exposed to cold spells in the 

 tropical sense. Xests adjoining the heaps of dead contained 

 living individuals acting as usual. Later, on August 8, at 

 Xelson, Xorth Queensland, I foimd the same species, dead in 

 similar heaps : if along a road, these heaps all seemed to be
