BUTLER ON LEPIDOPTERA [Mar. 19, diffused internally but defined externally by a whitish irregularly undulated stripe; fringes with whitish basal and dark brown central lines ; palpi below whitish. Expanse of wings 73-75 millim. Dry-season form §. Smaller; the angle of primaries less produced below apex; the secondaries with slightly larger and brighter ocelli; a small ocellus indicated on the first median interspace of the primaries : wings below olive-brown, the bands across the primaries lilac, but the apical patch whiter; three sharply defined ocelli coloured as on the upper surface-one small, on upper radial interspace, a second large on lower median interspace, and the third very small, below the second : secondaries with all the whitish markings ill-defined, but both ocelli clearly defined. Expanse of wings 66 millim. Fwambo. Four typical specimens and two females of the supposed dry-season form were obtained. It is, without question, by far the most beautiful Junonia hitherto discovered. Whilst deprecating the positive way in which Lepidopterists have, of late years, decided (without breeding in most instances) respecting the seasonal forms of Butterflies, I do not for a moment pretend to say that their conclusions are unlikely, in most instances, to prove correct. In the present case the two forms of female, though very different in aspect, are so evidently only modifications of the same species that it is but reasonable to conjecture that the smaller form with prominent ocelli is that of the dry-season. 26.

The whole of the specimens are very dark, larger than usual, and with the red ocellated belt narrower and slightly darker than in the majority of specimens; the under-surface colouring varies individually to an enormous extent, two examples exactly represent |
