Imago. — r^$. Mid-tibia not white above like hind tibia, 

 and no black streak behind cell on fore wing underside ; the 

 pale costal patch of fore wing upperside expands in the 

 submarginal region between SC 3 and R 2 , while in titan it is 

 much narrower, expanding only between SC 5 and R 1 ; a pale 

 line before R 3 . Hind tibia nearly as long as first and second 

 tarsal segments together ; short spurs not half length of long- 

 ones, these not half length of first tarsal segment. Distal 

 margin of fore wing about 3 mm. shorter than inner margin. 

 Expanse : $ 102-130 mm., ? 102-160 mm.
