While the inner transverse line is smooth bent, showing the outer two outwardly directed projections. In Saumfeld a distinct white wave line can be seen, which continues on the hind wings. Specimens with almost black middle and light root and Saumfeld are called f conversaria, those with more or less strong darkening and only slightly recognizable drawing elements as f nigricata. The antennae of the males are combed on both sides, those of the females are thready.
