 of forewing as upper surface but cell area greyish yellow; hindwing as upper surface, but costal 

 area darker than rest of brown areas and with small, dark brown marking at middle of anterior 

 margin of cell. Dorsal surface of abdominal segment 1 and 2 reddish orange medially, dark 

 brown and greyish yellow laterally; segments 3-8 weakly iridescent dark brown and dark blue,
