740 ZOOLOGY INSECTS. 



PAPILIO, (Linn.) Latr. 

 PAPILIO ZOLICAON, Boisd. 

 Papilio Zolicaon, STEECKEE, u Lepidoptera," pi. 6. MOKRIS, Syn. Am. Lep., 4. 



In Colorado, Zolicaon appears two or three weeks later than the other 

 Papilios. It inhabits all the mountainous parts of the Territory, was 

 brought by the expedition from Southern Utah, and occurs westward to the 

 Pacific Ocean. 



This species may be at once separated from P. Machaon, or its variety, 

 Aliaska, by the pupillated ocellus at the anal angle of secondaries. 



PAPILIO ASTEEIAS, Urury. 



Papilio Asterias, HARRIS, Insects Injurious to Vegetation. 

 Papilio Polyxenes (obsolete), KIRBY, Cat. Di. Lep., 1871. 

 A. Polyxenes, SCUD., Syn. List., 1875. 



This butterfly occurs rarely in Colorado, New Mexico, and California ; 

 eastward becoming more abundant. I have not found the species at eleva- 

 tions greater than 7,500 feet. Its time of flight is June and July. 



t PAPILIO BAIRDII, Edw. 

 Papilio Bairdii, EDW., Proc. But. Soc. Phila., 186G. 



Allied to Asterias; primaries more produced and narrower, and sec- 

 ondaries more rounded than in that species. 



Male. Expands four inches; upper side black; both wings crossed by 

 yellow bands as in Asterias, the spots being similarly shaped, but larger 

 than in that species, and fading gradually into the black ground on the inner 

 side ; at the anal angle a rounder black spot within a spot that is fulvous 

 above, yellow below. There is no trace of blue between the yellow bands 

 on secondaries, as there is in Asterias. 



Under side black ; marked as above, the yellow paler ; the end of the 

 cell on primaries a little yellow ; the outer ends only of the spots beyond 

 the cell on secondaries .very slightly fulvous ; each of the black spaces 

 between the yellow bands on secondaries a little sprinkled with blue scales. 



Body black ; shoulders brown-yellow ; two dorsal and a lateral row of 

 yellow spots on the abdomen. Edwards, I. c.
