Three males taken August 17 near the Rio de los Pinos present no difference from 

 those found in other parts of Colorado and New Mexico, which are smaller than those 

 from Mexico and Central America. 



It is easily distinguished from its near allies Rutulus, Turnus, and Eurymedon by the 

 narrowness of the black bands of wings and by the three tails to pj^ i niarie sr w/<_<^*«^«,

One male, much worn, taken July 27 at Weeminuche Creek, head of Tule Valley. 



This is the common representative of P. Turnus on the Rocky Mountains and Pacific 

 slope, from which it differs in the greater elongation of the wings, in the submarginal 

 row of yellow spots being confluent, and in the absence of the dimorphic black female.

 Papilio Machaon var. Californica, Meneteies, Cat. Mns. Petro. Lep. i, p. 69 (1855). 



At Pagosa Springs, July 21, two males. 



This is closely allied to P. Machaon, one of' the most obvious points of difference 

 being in the black pupil of the anal ocellus, which is absent in the latter. 



It feeds, in the larval state, on the umbelliferie, as do also its allies Machaon and 

 Asterius.

Near the crossing of upper road at the Rio Blanco, July 7, one female. 



This example is very large, and bears no traces whatever of the mesial band of yel- 

 low spots on eitlier wing. 



The species was frequently seen, though this was the only one captured. 



It has a wide range, occurring from Newfoundland south to Central America, and 

 from the Atlantic to the Pacific, and is subject to great and remarkable variations.
