Show 48 DR. A. G. BUTLER O N [Jan. 14, similar pale-bordered but indistinct markings; a discal increasing oblique belt slightly curved, with sinuated inner edge and diffused outer edge from subcostal to first median vein, from first median vein to inner margin abruptly narrowed and of equal width, slanting obliquely inwards; a chain-like double series of opposed lunules parallel to outer margin ; outer border rather paler (because more densely irrorated with pale ochreous) than the rest of the wing : secondaries crossed from just before middle by four pale ochreous bands, the first slightly irregular and sharply defined internally, diffused externally, continuing the discal belt of the primaries; the second and third continuing the chain-like series of the primaries, the fourth submarginal, less defined than the others, undulated ; outer border as in primaries. Wings below altogether paler than in the male, greyer, the discal belt of upper surface well defined, but pinky whitish on the secondaries; the basal area of these wings irrorated with pearl-grey indicating two vague subbasal bands ; the chain-like belt pearl-grey on both wings and with white points on the upper internal lunules of the primaries and the lower internal lunules of the secondaries. Expanse of wings 56 m m. Toro, June 16th. Prof. Aurivilhus has pointed out that the female figured by Karsch does not belong to this species and has named it D. karschi. A second female similarly coloured is in the collection; but, without the male, it would be rash to name it: in pattern it is not unlike D.felicia, but it is a much shorter-winged insect. PSEUDATHYMA PLUTONICA, sp. n. (Plate I. fig. 6.) Allied to P. sibyllina, but smaller, shorter in wing, the primaries with much less sinuous outer margin, the secondaries rounded, not produced at anal angle ; the discal belt of the primaries forming three patches, the first three divisions being much shorter than in P. sibyllina; the belt of the secondaries constricted towai'ds costa and not deeply indented externally; the inner submarginal line only white in the centre : on the under surface the markings on the basal area, excepting a costal patch on the secondaries, suffused. Expanse of wings 42 m m. Toro, in June. ACRCEA ORINATA Oberthiir. (Plate I. fig. 1.) 2 • This is the largest female of the group yet described, and much more nearly resembles the male of A. parrhasia than anything else : the primaries show a pinky-white, semitransparent, oblique, trifid bar beyond the cell in continuation of the discal tawny belt, and the basal area of the secondaries is almost wholly black: on the under surface this sex chiefly differs from A. orinata d in showing a diffused whitish patch beyond the cell of primaries. Expanse of wings 70 m m. Entebbe, April 30th. |
