ARCTIIDAE AND CTENUCHIDAE FORMERLY IN AUTOMOLIS 



5i 



present. Valve broad proximally with distinct saccular and costal regions. Uncus simple, 

 arched ventrally. Aedeagus with lobate, scobinate vesica and single, basal group of cornutal 

 spines. 



The affinities of this genus are uncertain. The single known species cannot be 

 placed satisfactorily, even tentatively, in any previously described genus. It 

 is probably distantly related to genera such as Selenarctia and Viviennea. 



Nothing is known about the early stages.
