Australia. 



The first group in this region is identical with the first 

 European group of Tephrosia. In the second group, which is 

 peculiar to Australia, the branches of the antennae of the male 

 are thickly ciliated, the hind tibiae are not incrassated, the wings 

 are oblong, and the exterior line of the fore wings forms abrupt 

 angles. In this group T. excursaria and the two following species 

 are included, and the next four species may be associated with 

 it, though they do not quite agree with the characters by which it is 

 distinguished. The third group is also Australian ; the antennae 

 are very variable in structure, and the wings have acute triangular 

 teelh. The fourth, fifth and sixth groups are less characteristic of 

 the genus.
