his attention to the subject. The above-named species belongs to a group in which the upper wings are triangular, and the inferior very much elongated, truncated towards the anal angle, and exteriorly drawn out into a long narrow tail. With the exception of the dark bands and occasional crimson spots, the whole wings are transparent. E. octavius expands about an inch and a half. The upper wings are transparent, the whole of the outer margin, and a band running obliquely across the middle, black. Under wings transparent anteriorly, the remainder, including the tail, black; the anal angle with a large crimson patch. The tail is very narrow, and somewhat whitish on the outer edge and at the tip. The under side resembles the upper, except that the red spots are each marked with two white points.
Found in Surinam.
