(3) Papilio rutulus Boisduval Plate, CXVI, rf 1 (The Pacific 

 Tiger). 



Closely resembling P. turnus, which it replaces on the Pacific 

 Coast in Washington and southward. The female is never di- 

 morphic; the marginal light spots on the under side of the fore 

 wings run together forming a continuous band, and are not 

 separate as in P. turnus. Expanse 3.50-4.25 inches. 



The larva feeds on alder and willows. 



(4) Papilio eurymedon Boisduval, Plate CXVII, d" (The 

 White-striped Tiger). 



Belonging to the same group as the two preceding species, 

 but distinguished by the pale creamy white color of the ground- 

 color of the wings, and by the fact that the submarginal spots 

 on the under side of the fore wings form, as in P. rutulus, a 

 continuous band. Expanse 3.50-4.00 inches. 



The caterpillar feeds on Rhamnus californicus and other 

 plants. The insect ranges from Mexico to British Columbia 

 and eastward to Colorado.

 Two-tailed Swallow-tail).
