Allied to Papilio A camas. The upper surface of the wings is of 

 a dark greenish black colour, with the incisures strongly marked 

 witli whitish buff; the hind wings have a rather long slender tail, 

 the denticulations, especially those between the tail and the anal 

 angle, being acute ; near the outer margin of the hind wings is a 

 row of seven whitish buff lunules, very slightly irrorated with 

 rosy scales. The under surface of the wings is of a greenish 

 brown colour, the fore wings having a portion of the anterior 

 margin irrorated with buff and fulvous scales^ and near the inner 

 angle of the wing are a few short oblong spots of the same colour, 

 very near to the outer margin ; the hind wings have a series of 

 seven black spots beyond the discoidal cell, most of which (but 

 especially those next the anal margin, which are the largest,) are 

 irrorated with carmine scales or dots, and halfway between this 

 row and the outer margin of the wings is a row of small pale car- 

 mine-coloured lunules, the one nearest the anal angle being dupli- 

 cated and preceded by a black patch uniting it with the spot above. 

 The neck and sides of the body are spotted with fulvous.
