Desc. Superior wings above fulvous, anterior margin blaek, 

 with white clots; exterior margin black, with a double series of 

 white dots ; the black at the tip is very broad, and contains a 

 dilated, interrupted, and abbreviated fulvous band, and several 

 pale fulvous spots ; po.sterior margin black, immaculate ; beneath 

 as above, but the spots are of a purer white ; inferior wings en- 

 tire, sometimes a little crenate, fulvous, with a black posterior, 

 and half of the exterior margins black, the former with a double 

 row of white spots, of which those of the middle are sometimes 

 nearly obsolete, outer margin with a single series of three or four 

 white spots ; nervures of the disk margined with fuscous, with 

 an elevated spot behind the middle, on the third nervure from 

 the inner margin ; beneath ochreous, in other respects resembling 

 the superior surface, but the spots ai-e of a purer white and 

 larger, the nervures are more dilated, black, edged more or less 

 deeply with white ; body black, with numerous white dots on the 

 trunk, and a few on the head and neck above ] feet blued black. 



Ohs. The black margin of the superior surface of the wings 

 has an opalescent gloss in a particular light. The larva is an- 

 nulate with black and white, with two slender processes on the 

 anterior part of the body, and two on the posterior part. The 

 pupa is of a delicate green color, with dots of burnished gold. It 

 feeds on different species of Asclepias, and is very abundant in 

 the neighborhood of Philadelphia, on the A. syriaca, and accord- 

 ing to Abbott in South Carolina, on the A. cnrassavica. I con- 

 sider the present as the plexippu!<, on the authority of Gmelin, 

 who in his edition of the Systemata Nature, states its native 

 country to be North America. I have of course omitted many 

 synonyms and references which that author has inserted, as I 

 consider them to be doubtful. Catesby's figure cannot be mis- 

 taken ; he states that the species is " common in most of the 

 northern colonies in America."
