Upper Side. The anterior wings are entirely dark brown, without any spots or marks. — The posterior 

 wings the same, with four tails, the inner ones much longer than the others ; close above which latter 

 are two red spots, edged at the bottom with black, and two more, placed at the anal angle. The cilia 

 is white. 



Under Side. All the wings are of a dark lead colour. A very narrow black and white line crosses 

 the anterior wings, parallel to the external edges ; another indented irregular line crosses the posterior 

 wings, beginning near the middle of the anterior edge, and meeting just below the extremity of the 

 Ijody. Four long reddish spots are very visible on this side, below which are four black ones. 



This species is nearly allied to Papilio Echion, Linn. Syst. Nat. p. 788. figured by 

 Roesel, torn. i. tab. 7- f- 3- 4. which is also an American species, but differs, as Drur^ 

 observes, in wanting the red spots on the upper surface of the lower wings, in having a red 

 line crossing the wings on the under side, &.c.

 like hairs, of a chocolate colour ; the tips being white.

 greyish flesh colour. A narrow silver line begins at the anterior edge, about a third from the tips, and 

 crossing both superior and inferior wings, meets near the extremity of the abdomen, running across the 

 inferior wings in a very irregular, indented manner, and having its upper side verged with chocolate. The
