Separating Pericyma glaucinans and Pericyma albidens

From images on Bold Systems and the descriptions in FBI, Hampson, Vol. 2 and MON Part 3, the post-medial line in Pericyma glaucinans is incurved beyond cell, and then oblique to inner margin. In Pericyma albidens, the postmedial line is more or less straight, with a small kink at v.4. In Pericyma albidens, the medial black line, curves in to costa, while in Pericyma glaucinans, it is largely parallel to the postmedial. One of the brown forms of Pericyma creugeri is also similar.
