anal area; granulation fine; costal expansion not very projecting; 
branches of R indistinct, irregular, connected with few cross veins; 
Ri, M and CuA very indistinct; cross veins faintly visible, few, mostly 
regular.

of the genus in largest, relatively narrowest and apparently thickest 
tegmina with broadest sutural margin and very indistinct Ri, M and

Genus Austrelytron, new genus 
Fore wing: tegminous, relatively small; sutural margin narrow; 
wing surface covered by dense granulation and isolated, pointed 
tubercles, which also form rows on the veins; costal expansion not 
very projecting; wings broadest before the middle of the wing, nar- 
rowing quickly towards the apex; anterior margin convex, posterior 
margin slightly concave; main veins with few branches; Sc with 
two or more branches parallel to each other, terminating well before 
apex; R sending off several irregular branches towards Sc; Rs, dis- 
tinct, originating after the middle of the wing; CuP long, concave; 
about three unbranched anal veins; cross veins few, simple.
