Aneono gen. nov. 



Differs from all other Eupteryginae by the venation of the 

 tegmina, which is best explained by the figures. It is remark- 



♦ It is a pity that Baker has applied the misleading term ' Prota/ebra' to this genus, 

 as it is evidently a derivative of that genus or some ally not a precursor.
