Book excerpt: Excerpt from Proceedings of the Entomological Society of Philadelphia, Vol. 3: April June, 1864 Size moderate; form slight; wings broad; anterior wings with the internal margin straight, external margin moderately oblique and rounded, costal margin slightly rounded, 12-veined, veins 5 and 6 free, vein 4 equidistant from 3 and 5 at base, discal cell open, subcostal cell small, elongate, its lower marginal vein indented midway between each extremity; posterior wings 8-veined, veins 1 and 2 free to base, veins 8 and 7 (costal and subcostal) diverging from a common stem at the extreme base; antennae moderate, simple; tongue short; thorax moderately clothed with fine short hair; abdomen moderately stout, slightly exceeding the posterior wings, smooth, not crested; palpi slight, hardly exceeding the front; legs moderate, evenly clothed with short pubescence, hind tibiae with four moderately stout spurs. I erect this genus for a delicate Noctuid belonging to M. Boisduval's Heliothidae, the ornamentation of which is peculiar and different from anything I have yet met with in the Noctuina. The ordinary spots and lines are absent except the transverse posterior line which is indicated by the difference of coloring between the median and subterminal spaces and by a series of white dots on the veins. At the outer extremity of the discal space, at the base of vein 5, is a small neatly defined rounded ocellus with a whitish center, annulated with reddish, and a second, larger, and with a blackish center, is situated on the median vein anterior to its furcation; these ocelli at first sight seem to indicate a corresponding vein structure, which, on denuding the wing of scales, is seen not to be the case. The pterogostic structure resembles that of Anth cia (marginata); the subcostal cell is broader at the middle and vein 4 is not so near 8 at its base; the tongue is shorter, wings relatively broader than in Anth cia. The eyes in the dried specimen are ornamented with petal-shaped marks, diverging, like radii, from a common center.
