LEriDOPTEEA PAPILIONIDAE PAPILIO DAUNUS. 741 



This species belongs to the group of Papilios, of which Machaon is the 

 type, and is one of a number of forms closely related to Asterias, and 

 probably derived from that species. All of these are characterized by the 

 spotted abdomen ; that of Machaon is banded. The larvae of the whole 

 group feed on umbelliferous plants. P. Sairdii is still excessively rare in 

 collections. A single specimen, the original type, was brought from Arizona 

 in 1865, and the expedition took specimens in New Mexico in 1871, and in 



Arizona in 1873. 



t PAPILIO PILUMNUS, Boisd. 



Papilio Pilummis, STEECKEE, Illustrations of Lepidoptera, 1873. 



This species was taken by the expedition in 1871. It occurs in New 

 Mexico and southward. 



PAPILIO TURNUS, Linu. 



This common eastern species has occasionally been found in the Rocky 

 Mountains, which seem to be the limit of its westward range. 



PAPILIO RUTULUS, Boisd. 

 Papilio Rutulm, EDW., Butterflies N. A., ii. REAKIRT, Proc. Ent. Soc. Phila., 1866. 



This species is very closely allied to P. Turnus. The only constant dis- 

 tinction seems to be that in Rutulus the submarginal ray on the under side 

 of secondaries is continuous ; in Turnus it is broken up into distinct spots. 

 No melanized females of this species are known. All the specimens have 

 rather elongated hind wings, as is the case with New England specimens of 

 Turnus. The female is not so heavily marked with blue on the secondaries 

 as in the latter species, but occasional specimens from the Eastern States 

 approach very closely in marking to the normal female of Rutulus. 



Rutulus was brought by the expedition from Southern Utah ; is taken 

 in Colorado in the month of June, there frequenting open woods and hill- 

 sides where flowers are abundant. It is common in California. In Colorado, 

 there is no second brood of Papilio.
