Pangrapta
viridigrisea sp. n.
 , 15-16mm. The facies is similar to that of holophaea
except
the ground colour is greyer, and the green markings duller, darker, reduced
relative to the darker fasciation. The postmedials are more finely irregular,
this being particularly so on the forewing, and on the underside; on the
underside of holophaea all wings have two dark, more or less parallel,
straight fasciae, except the forewing postmedial has its usual angle, whereas in
viridigrisea
the
fasciae are rather broken and irregular. In the male genitalia, the valves are
more strongly curved at two-thirds than in holophaea and
the saccular spines are very much longer. The ornamentation of the vesica is
similar except the cornuti at the ends of the two long diverticula are more
symmetrically shaped. In the genitalia, viridigrisea has sclerotisation and scobination
extending closer to the base of the corpus bursae than in holophaea.
