Head : Dark brown with purplish iridescence dorsally, with light orange, erect scales above compound eyes laterally. Antenna with slender basal segment, dark brown dorsally; flagellum slightly serrate (Fig. 10B), dark brown in basal 3/5, then white beyond. Labial palpus with 2 nd segment thickened, saber-shaped, pale grayish orange ventrally, densely covered with dark-brown scales dorsally; 3 rd segment slender, longer than 2 nd segment, light orange dorsally, dark brown ventrally, apex sharply pointed. Thorax : Notum and tegula dark brown, with purplish iridescence dorsally. Hind tibia light orange dorsally; black scales on outer surface in basal 2/5, pale orange in median 1/5, and black scales all around in distal 2/5, with light orange apex; first tarsus dark brown, others light orange dorsally. Forewing elongate, length more than 5 times the width in middle; ground color dark brown, with purplish iridescence; antemedian fascia black, oblique, extending from costa to inner margin; postmedian fascia indistinct; costa slightly convex in basal 1/4, then slightly concave, more strongly oblique beyond 3/4; apex more or less rounded; termen slightly oblique; fringe concolorous, with narrow orange white basal line; cell closed; venation similar to that of P. pilosa ( Fig. 8D ). Hind wing about 1.5 times broader than forewing, deep yellowish brown. Abdomen : Pale orange from 1 st to 4 th segment and fuscous beyond on ventral surface. Female genitalia (Figs. 10C, D) with abdominal sternite VIII deeply incised medially. Apophyses anteriores short, about half the length of apophyses posteriores; apophyses posteriores long, slender, about 1.3 times the width of antrum. Ostium bursae narrowly emarginated. Lamella antevaginalis very characteristic, broad as wide as the width of segment VII, weakly sclerotized, with irregular wrinkles, especially in caudal half. Antrum broad, indistinct, membraneous. Ductus bursae extremely broadened posteriorly, tapering toward the junction with corpus bursae; junction rather constricted. Corpus bursae ovate, about half the length of ductus bursae; signum large, round, with a sclerotized line positioned diagonally about 1/4 from the posterior side, and with another sclerotized line longitudinal from near center to the anterior end; posterior part more heavily sclerotized. Distribution. Uganda . Etymology. The species epithet is derived from the Latin,— enormis (=huge, vast) with a Latin diminutive suffix,— ella.
