tapering. Wings with the sectors of the arculus stalked ; 

 no supra-triangular nervules ; one cross-nervule only in the 

 lower basal cell ; nodal sector very slightly waved. Fore 

 wings with the triangle traversed, followed by three rows 

 of cells, only increasing to four towards the extremity, three 

 cells in the subtriangular space. Hind wings much broader 

 than the fore wings, the triangle free, its base slightly nearer 

 the base of the wing than the arculus. On the fore wings 

 the arculus lies between the first and second antenodal cross- 

 nervules, on the hind wings it lies just within the level of 

 the second. Sectors of the arculus slightly separated at the 

 base on both the fore and hind wings. 



Agrees with Corduliops, Karsch, in many of its characters ; 

 but in Corduliops the triangle of the fore wings shows a 

 tendency to become trapeziform, and the hind wiugs are not 

 narrower than the fore wings.
