Fulva, alis anticis medio, posticisque albidis, illarum basi fulvo, maculis 6 parvis nigris, dimidio apicali obscuriori. (Expans. Alar. 2 unc. 9 lin.) SYN. Phalæna (Noctua) Speciosa, _Drury_, _App. vol._ 2. HABITAT: Sierra Leone. _Upper Side._ Antennæ black, setaceous. Tongue long and spiral. Head, neck, thorax, and abdomen yellow. Anterior wings pale clay-coloured; but next the shoulders yellow, gradually changing to a white towards the middle of the wings, and occupying almost half of them; each wing having six small black spots on the yellow part, three being placed on the anterior edge, and the other three near the shoulder, where likewise is another small spot. Posterior wings white, immaculate. _Under Side._ Palpi long and yellow at the base, but the ends are black and filiform. Legs white, striped with brown. Breast and abdomen white. Anterior wings with the tips pale clay-coloured, as on the upper side; all the remaining part being white. A small black bar begins about the middle of {11}the anterior margin, and crossing the wing ends at the lower corner. Next the shoulders is a small tuft of hairs of a silver colour placed on each wing. Posterior wings white and immaculate. The margin of the wings entire. This and several nearly allied species of tropical moths constitute a very distinct subgenus characterized by the prevailing colour, the spots at the base of the wings, the elongated palpi, and the peculiar neuration of the anterior wings. I have not, however, ventured to propose the establishment of a subgenus for them. They appear in some respects to be allied to the genus Leucania. CALLIMORPHA? PYLOTIS. Plate V. fig. 3.

Head, thorax, and abdomen fine mazarine blue. Anterior wings dark mazarine, having a single white bar running from the middle of the anterior edge to the lower corner. A small part of the cilia at the tips is white, the rest being of the same colour as the wings. Posterior wings of the same colour as the superior, and immaculate, except the cilia, which is entirely white.
