Although closely allied to Yjysolophus, this genus (which I for- 

 merly included with it) appears to be naturally and satisfactorily 

 separated from it by the character of veins 2 and 3 of forewings, 

 which are remote and parallel, whilst in Ypsolophtis they are 

 stalked. It is represented by a few European species, but will 

 probably be found spread through the Indo-Malayan region, and 

 appears to be fairly numerous in Australia, especially perhaps in 

 the interior. Imago with forewings elongate, more pointed and 

 termen much more oblique than in Yjysoloplnis.
