1120 REVISION OF AUSTRALIAN LEPIDOPTERA, 



subclavate. Posterior tibiae densely rough-haired. Forewings 

 with vein 7 from angle, 8 and 9 out of 10, rising much before 

 angle. Hindwings as in forewings. 



Easily known by the neuration ; the antennal characters vary 

 specifically in the ^, and all gradations can be found from strong 

 pectinations to extremely short hardly noticeable dentations ; they 

 are very serviceable for specific distinction, but afford no practi- 

 ble basis for generic separation. The genus is characteristic of 

 Australia and New Zealand, but I have also seen a species from 

 South Africa.
