THE ARGENTINE ANT AND OTHER EXOTIC ANTS 
the Argentine Ant had not appeared. It is interesting to 
note that in each country where humilis has been introduced 
it has displaced the native species. 
The following is a list of the various ants found in the 
immediate neighbourhood, but not found in the area invaded 
by the Argentine Ant. 
PONERINAE. 
1. Chalcoponera metallica (Smith). 
2. Chalcoponera victoriae Andre. 
Myrmicinae. 
3. Monomorium cincta Wheeler. 
4. Pheidole yarrensis Forel. 
Dolichoderinae. 
5. Iridomyrmex rufoniger (Lowne). 
6. Iridomyrmex domestica Forel. 
7. Iridomyrmex nitidiceps Andre. 
8. Iridomyrmex punctatissima Emery. 
9. Teclinomyrmex albipes (Smith). 
10. Teclinomyrmex jocosus Forel. 
Formicinae. 
11. Paratrechina (Nylanderia) ohscura (Mayr). 
12. Camponotus (Tanaemyrmex) consohrinus (Erichson). 
Of the above, the first two are beneficial as they destroy 
other insects. Both, however, sting severely and on that 
account are not always welcome in the garden. Numbers 
three and four are pests in the garden as both species are 
harvesting ants. They gather seeds which they carry to their 
nests as food. Numbers five and six are well-known house 
pests in most parts of Australia, but rarely appear in large 
numbers. Seven and eight are common in gardens but rarely 
enter houses. Nine is an introduced house ant which gives a 
lot of trouble, and as a house pest is almost as bad as the 
Argentine Ant; it is found in most of the coastal cities of 
Australia. It is generally known as the black house-ant. 
Ten and eleven rarely enter houses and are not abundant 
anywhere. Twelve is the common Sugar Ant, found abundant 
everywhere in Australia and Tasmania. It can be controlled 
with ease. 
With very few exceptions, all the ants which cause serious 
trouble in houses and stores in Australia have been introduced
