 costa to a little beneath lower discoidal nervule, a rounded spot on second median nervule, a broad short 

 fascia extending from second median nervule to near inner margin, and two marginal series of spots placed 

 between the nervule s. Posterior wings with the following fuacous markings : — two short oblique basal 

 fasciae, a short transverse fascia extending from abdominal margin to second median nervule, a similar 

 central one placed nearer margin, a short curved fascia near apex and two marginal series of spots placed
