644 REVISION OF AUSTRALIAN LKPIDOPTERA, V., 



with 3 and 4 separate, 6 separate, 11 anastouiosiug strongly witli 

 12 and 10, sometimes the anastomosis with 12 is replaced by a 

 short connecting bar. Hind wings with 3 and 4 separate, G and 

 7 separate, 8 closely approximated to cell from near base to 

 beyond middle; discocellulars not angled, l)ut rather strongly 

 inwardly curved, only slightly oblique. 



Type, Oeuochlora imperialis Warr. The true position of this 

 genus is not open to doubt. The only important character in 

 which it differs from Terpna is the longer approximation of 

 vein 8 of hindwings to the cell, a primitive trait in which it 

 agrees with Rhuma and Heliomystis.
