8. PAPILIO POLYDAMAS, Linn. 



Expanse of wings 3.5 inches. 



Color of upper surface greenish black ; a single row 

 of yellow spots to each wing, nearly parallel with the 

 outer margin. The apex is more produced than in the 

 preceding species, and the row of spots only partly fol- 

 lows the flexures ; the row on the hind Avings not curved 

 so much as the outer margin, and forming a continuous 

 band but for the black veins. No ocellus or tail. 



On the under side the black has a brownish tinge ; 

 the yellow spots of the fore wings are repeated except 

 towards the apex, but the yellow spots of the hind wings 

 are absent ; but close to the margin are seven red spots, 

 the anal one a bar, the rest more or less figure-3-shaped. 



Body black, with a narrow orange stripe on each side ? 

 and orange spots on the collar.
