is about 12 mm. The forewings have a leaden grey basal patch, merging outwardly into tawny purplish fuscous, which reaches to one-third and is bounded on the costa by a cuneiform white costal streak, while from its lower half it sends obliquely upward a sharp steel-grey tooth-like projection into the deep brownish orange band which succeeds it. From each extremity of the white costal streak a dark steel-grey point also projects outward and the broad orange band into which these project is bounded a little beyond the middle of the wing by a rather oblique bright steel-grey fascia, narrowly margined on either side by black, and rather wider on the dorsum than on the costa. This again is succeeded by a deep reddish orange fascia, narrower than the preceding orange band, but somewhat produced outward on the dorsum. Above this dorsal extension is a deep blackish patch extending to the costa and produced outward nearly to the apex, this contains a pair of rather converging silvery white costal streaks and a small spot of steel-grey towards its lower extremity, the space beyond it to the apex and termen, including the cilia, being rich shining purple. The hindwings are dark coppery brown.Biol. centr.-amer. Lep. Heterocera 4 : 80
