Arenacea. Lutea, alis superioribus supra atomis nigris adspersis. (Expans. Alar. 1 unc. 3 lin.) Syn. PhalÆna (Bombyx) arenacea, Linn. Syst. Nat. 2. p. 828. No. 65. Habitat: Cape of Good Hope. Upper Side. AntennÆ pectinated, and of a yellow clay colour. The head and thorax yellow, but covered over with hairs in such manner that the former cannot be distinguished. The abdomen, superior and inferior wings yellow. On the anterior wings appear some very minute black spots scattered thereon in a very irregular manner. The wings are entire. Under Side. The thighs, breast, and abdomen are very hairy. The superior and inferior wings of the same yellow colour as on the upper side, without a mark of any kind. This insect appears most nearly to approach the genus Limacodes, Latr. SATURNIA CECROPIA.Plate XVIII. fig. 2. Order: Lepidoptera. Section: Nocturna. Family: BombycidÆ. Genus. Saturnia, Schrank. Latr.

Enc. MÉth. 5. p. 25. 5. Habitat: New York (Drury). North America (Linn. &c.). Upper Side. AntennÆ very broad, pectinated and black. The head is small and red. Neck white. Thorax covered with long orange-brown hairs. Abdomen alternately with broad stripes of white and orange brown, the latter being edged behind with black. Anterior wings, with two bars crossing from the anterior to the posterior edges, one at about three-fourths of an inch from the shoulders, whitish, edged on the outside with black; the other is orange, at about an inch distance from the external margin. The base of the wing is a fine orange brown. The middle is deep rusty brown, which, towards the upper part, is powdered with buff-coloured hairs. In the middle of this is a large white spot verged with black, somewhat resembling a kidney bean, and is broadly tinged behind with red brown. The extremity of this wing, next the bar, is the same dark brown, and powdered, having a black spot about Under Side. The markings on all the wings are more distinct, and brighter than on the upper. The posterior wings, and the major part of the anterior, being covered with dust-like buff hairs, except the spots and buff margins round the edges. The posterior wings along the anterior edges being verged with white, which becomes broader as it approaches the shoulders. The caterpillar of this fine moth feeds upon the wild American plum (Prunus Pensylvanica), garden plum, &c. It is thick and fleshy, of a pale green colour, with a pair of small blue spots on each segment, and with two rows of short and setose yellow dorsal tubercles. One observed by Abbot, spun up on the 17th of June, and the moth came out on the 30th of March following. The cocoon is attached to a twig. The outside web is coarse, and the inner covered with silk, like a silk-worm's cocoon. Abbot states that this silk has been carded, spun, and made into stockings, and that it will wash like linen. The species is, however, too rare to be of any utility in Georgia. It is, however, much more abundant in the neighbourhood of New York, and has been bred in England from some brought over in the chrysalis state. It is difficult to rear it in confinement.

AntennÆ filiform, and cream-coloured at the base, but black at their extremities. The tongue is small, and curled up. The neck red, having two small black streaks above it. The thorax and abdomen cream-coloured. On the former are three black streaks. On each annulus of the abdomen is a black spot, and another on each side. Anterior wings cream-coloured, with many black spots and marks thereon, of different forms and sizes, and varying very greatly in different specimens. The Under Side. The colours are more faint and dirty than those on the upper. Anterior femora red, with two black spots thereon, close to the head. Tarsi black and cream-coloured. The caterpillar of this insect is brown, with five pale longitudinal lines, and with long hairs arising from fulvous tubercles. It feeds, according to Abbot, upon plantain, corn, peas, and many other plants. A specimen observed by this author was hatched on the 23d of July, spun up on the 28th of August, and the moth appeared on the 9th of September. It is said occasionally to make great devastation among Indian corn. Sir J. E. Smith ascertained the specific identity of this insect from Dr. Hunter's Museum, examined by Fabricius, who has neglected to cite Drury's figure. SPILOSOMA CUNEA.Plate XVIII. fig. 4. Order: Lepidoptera. Section: Nocturna. Family: ArctiidÆ. Genus. Spilosoma, Steph. Arctia, Latr. Eyprepia, Ochs. PhalÆna (Noctua),Drury. Spilosoma Cunea. Alis albis, anticis maculis permultis, posticis duabus nigris, abdomine concolori nigro-maculato. (Expans. Alar. 1 unc. 5 lin.) Syn. PhalÆna (Bombyx) Cunea, Drury, App. v. 2. PhalÆna punctatissima, Abbot and Smith, Ins. Georg. t. 70? Habitat: New York (Drury). Georgia and Virginia (Abbot and Smith). Upper Side. AntennÆ pectinated and black. There is no appearance of any tongue. Head white. Back and abdomen ash colour. Anterior wings white, with a great number of spots differently shaped of a sooty black colour. On the external margin are five spots, those nearest the tips being shaped like triangles. Posterior wings white, with a sooty spot on each near the external edge, and a very faint small mark near the exterior angle. Under Side. Legs black. Breast and abdomen ash colour. The wings marked as on the upper side. There seems little reason for doubting that this is identical with the PhalÆna punctatissima of Abbot and Smith, of which the female is entirely white. The last named species feeds upon the mulberry, persimmon, willow, and wild cherry of America. One observed by Abbot spun up on the 16th of May, and came out on the 1st of June. The whole brood of caterpillars feed together in a web, and will often entirely destroy the leaves of a small tree. The name proposed by Drury evidently alludes to the triangular spots on the margin of the anterior wings, and seems quite as expressive as that employed by Sir J. E. Smith, who seems to have treated Drury's work on several occasions as scarcely deserving of notice. NOCTUA (ACONTIA?) NUNDINA.Plate XVIII. fig. 5. Order: Lepidoptera. Section: Nocturna.

AntennÆ thread-like, of a reddish brown. The tongue curled spirally. Head and thorax ash colour. Anterior wings the same, whereon are several faint marks of a light sand colour. Close to the anterior margin, about a third from the tips, is a black mark, resembling an I of the German text characters. Posterior wings silvery white, with a small, faint, light, sandy border, and a small oblong brown discoidal spot. Under Side. Anterior wings silvery white, with a faint indistinct dark brown border running along the external margin, and two dark marks opposite the German text character. Posterior wings silvery white; the oblong brown spots are here plainly seen as on the upper side. |
