full, frequently more or less double and ending behind in a rounded or feebly biangulate
point at the median line; post-dorsal wing low, obliterated in old specimens; upper
anterior edge either slightly angled or rounded; base line curved; epidermis greenish-
brown or brownish-green, rarely faintly rayed, but showing about three broad, dark rays
on the posterior slope; beak cavities varying from shallow to moderately deep, not
