Castnia Licus, Latr. et God. Enc. MÉth. ix. p. 797. Habitat: Surinam. Upper Side. The antennÆ are dark brown, at the tips paler; and terminating in a point. The head, thorax, and base of the abdomen dark chocolate brown; the extremity and sides of the latter dark. Anterior wings of a fine deep chocolate brown. A narrow, irregular, and oblique cream-coloured bar runs across the wing; between this and the tip, from the anterior edge, runs another crooked irregular bar, of a much darker colour, reaching almost half across the wing towards the interior angle, the external margin being of a lighter shade. Posterior wings, having a white bar running transversely across the wing, widening by degrees, and ending at the anal angle. Six square orange spots also of different sizes, are placed within the external margin of these wings. Under Side. Anterior wings, in the middle, dark chocolate; the tips dark fawn colour, lighter next the shoulders. The two irregular bars, on the upper side, are here a little broader. Within the external edge are three rather pearly white spots. Posterior wings greyish fawn colour, with the The genus Castnia is another of those curious anomalous forms, which exhibit the characters of several groups. The general form of the wings is that of a moth, whilst the variegated colours, indicating diurnal flight, and the structure of the antennÆ are those of a butterfly. It is much to be regretted, that travellers in South America have not ascertained the preparatory states of this extraordinary group, which alone will enable us satisfactorily to ascertain its real relations. GASTROPACHA? OTUS.Plate XVI. fig. 3. Order: Lepidoptera. Section: Nocturna. Family: BombycidÆ, Steph. Genus. Gastropacha? Ochsenh. Sphinx, Drury. Gastropacha? Otus. Alis elongatis integris luteo-fuscis, anticis fasciis duabus denticulatis nigris. (Expans. Alar. 4 unc. 6 lin.) Syn. Sphinx Otus. Drury, Append. v. 2. Bombyx Agrius, Oliv. Enc. MÉth. 5. 39. 56. Habitat: Smyrna (Drury). Upper Side. The antennÆ and head are of a reddish brown; the former are strongly pectinated, and very broad in the middle, but at the extremities very narrow and curled. Thorax dark brown. Abdomen reaching half an inch below the wings of a reddish dun colour. Anterior wings dun colour; with a large spot or patch, of a darker colour, situated on the posterior margin, near the base. Two indented black lines run obliquely from the anterior edge, near the tip, to the posterior near the middle; the space between them being rather lighter than the rest. Posterior wings dun colour, immaculate. All the wings, both on the under and upper sides, appear very shining and glossy; the scales or feathers appearing, when viewed through a microscope, very coarse and long. There is no tongue discoverable in this moth. Under Side. Breast and sides bright dun. The abdomen reddish dun. All the wings dun-coloured. The lower indented line appears faintly through the wing, of a dark brown colour, also a faint reddish brown indented line runs across the posterior wings. The edges of all the wings are entire. This insect, which appears to have been overlooked by modern authors, seems to form a connecting link between Zeuzera and Gastropacha, agreeing with the former in the general form, and with the latter in the transverse denticulated fasciÆ on the anterior wings, and the curved antennÆ feathered to the tips. |
