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 excep- 

 tion of the dark bands and occasional crimson spots, 

 the whole wings are transparent. E. octavius ex- 

 pands 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.
