DESCRIPTION. 



Body yellow. Head above black, below tufted with yellow : trunk and abdomen striped with 

 black and yellow : wings yellow ; primaries with five abbreviated black subangular bands ; the two 

 inner ones being common to both wings, the innermost of these bands is marginal and its lower 

 attenuated extremity converges with that of the penultimate band, reckoning from the tip; the 

 anterior margin of the primary wings is edged with black, with yellow scales intermixed, and two 

 longitudinal yellow streaks between the middle and the apex; the posterior margin has a broad 

 black stripe with an articular 9 yellow band ; in the secondary wings the discoidal basilar area is dis- 

 tinguished by a black streak at the apex; the posterior margin has abroad black band with a double 

 transverse series of crescents, each series consisting of four spots, the internal series being bluish, 

 and the external yellow ; there is besides an orange spot at the anal angle, and another at the external 

 margin ; this margin is indented, with the concavities fringed with yellow ; the angle between the 

 fourth and fifth indentures projects into a short tail ; the underside of the wings is yellow, but paler 

 than the upperside; there are also the five black bands: the posterior margin of the primary wings 

 has an interior ash-coloured band and exterior yellow one, included between three narrow black ones: 

 the underside of the secondary wings is not very different from the upper, except that the posterior 

 margin is not nearly so black ; and at the anal angle there is a spurious ocellus consisting of a black 

 semicircle, a blue crescent, a black, and lastly an orange transverse spot. The legs of this species 

 are black, as are also the nervures of both wings. 



Fabricius says that this species is thrice the size of P. Machaon, but the specimens I received, 

 of which there were several, were of the same size. In Mouffet's figure, referred to by Ray, which 

 appears to belong to the insect here described, the expansion of the wings is eight inches, but his 

 imagination has evidently been employed in drawing that figure, which is represented with falcated 

 primary wings. Probably it was drawn from a mutilated specimen. He has made the blue spots 

 of the secondary wings circular, looked at in certain lights they appear so. Probably those in the 

 warmer parts of America may be larger than the northern ones.
