Genus CAMPONOTUS Mayr 1861. 
Subgenus Tanaemyrmex Ashmede 1905. 
Camponotus ( Tanaemyrmex ) consobrinus (Erichson). 
This common and widely distributed species was found at 
Gellibrand. 
Having examined many largejseries of all forms of this 
species from all parts of Tasmania and the mainland I can 
find nothing in which to justify the retention of Roger’s name, 
The differences in the clypeus and size mentioned by Roger for 
dimidiatus are found in all series of consobrinus from Tasmania.
