Northern and eastern form.
Differs as follows: Wings on the whole longer and narrower; hyaline markings, especially in interspace 1 of forewing and in cells of both forewing and hindwing, very much broader.
In many specimens the black ground colour in these spaces is reduced to a mere slender black line enclosed in the subhyaline marking.
On the underside the streaks are often much blurred and diffuse.

Wingspan 70–100 mm.
