conidæ. They certainly bear a very striking general resemblance to the Heleconian butterflies, and the analogy must be admitted to be close.
A. Tiresia measures three inches and three-quarters between the extremities of the wings: the upper pair are deep black with two broad, opaque, deep yellow bands lying obliquely across the surface, one near the middle, the other, somewhat abbreviated, towards the apex, and a patch of the same colour on the hinder border before the middle; the base with a few small white spots, and a remote series of the same near the exterior margin and parallel with it. The hinder wings are yellow, with a broad black border bearing a marginal row of white spots: anterior part of the thorax spotted with white; abdomen brown.
A. heleconides. Colours and the mode of their distribution precisely as in the preceding species, but the yellow paler, approaching to yellowish-white, and the bars and spots transparent. Expansion of the wings three inches. Swainson's Zool. Illus., pl. 124, fig. 2.
