 curved, edged inwardly with yellowish ; second line brown, 

 curved outwards, but bent back to the costa, edged outside 

 with yellowish ; the space between these two lines filled up

 Hind wings very pale fulvous, with a partial, transverse, pale

 and with darker, or olive- brown, on the sides; dorsal line 

 darker, threadlike ; a conspicuous stripe of white lines, start-
