The three forms, irafe/m, Edw ; telamonides, Feld., and marcellus, Bd., 

 are doubtless found throughout the State. All have been taken by the 

 writer in Monroe and Vigo counties. Of the three, marcellus is much (he 

 more common, walshii being comparatively scarce, though Edwards, loc. 

 cit. p. 9, says " that Dr. G. M. Levette has taken it abundantly in the 

 month of April near Indianapolis." The food plant is pawpaw. The 

 butterfly frequents open woods and winters in chrysalid.

Throughout the State. The larvae are said to feed upon the different 

 species of Aristolochia, or pipe vine, but the plants of that genus are rare 

 in Indiana, whereas the butterfly is a common one, hence there must be 

 some other food plant. Found from May 1, to September 20, in 

 open woods and pastures. According to Riley, another food plant of the 

 larvae is Asarum canadense, or wild ginger, a common plant on rich hill- 

 sides in Indiana.

This handsome Papilio inhabits all parts of the State, but next to P. 

 cresphontes is the least common member of the genus found with us. Its 

 larva is the well-known carrot or parsnip worm found on the various wild 

 'and cultivated species of Umbelliferce. 



The butterfly is most common in July and August, in open woods, es- 

 pecially those containing thistles. It winters in the chrysalid, the first 

 ones appearing about May 15.
