metathoracic tibia with two pairs of spurs. Retinaculum short; venation as in Text-figs 19 

 and 20. 



9. As ^ but antennae hardly serrate ; long setae restricted to lateral margin of each segment. 

 Forewing broader than in £ and hindwing relatively larger. 



$ genitalia. Juxta with (canalis) or without (pulverosa) medial globosity; lateral arms free 

 in pulverosa, not free in canalis. Apex of valve bifurcate or simple. Uncus simple. Aedeagus 

 without processes; vesica partly scobinate. Eighth abdominal tergite with weakly developed 

 apodemes. 



Cj genitalia [§ of canalis not known]. See description of pulverosa. 



The affinities of this genus are doubtful, but it is fairly closely related to Idalus 

 and allied genera of Phaegopterini which have reduced hindwings and a clear 

 distinction between costa and sacculus of the valve in the male genitalia. 



Two species are known. Nothing is known about their early stages.
