NORTH AMERICAN WITTERFLIES. 5 



Habitat, U. S., excepting N. Eng. north of Mass.; also Ont. 

 Occurs in the north in June and July; in the south from May un- 

 til November. 



3. PAPILIO MACHAON Linn. 



Swallow-tail. 

 General coloration similar to the type, P. turnus, but the first dark 

 band above that crosses both wings is wanting, this being replaced on 

 the fore wings by a dusky patch that occupies the basal portion of the 

 wing; the second inner band is shorter and does not cross the central 

 cell. On the secondaries the upper and lower sub-marginal spots are 

 yellow, not orange, and the marginal black band is widened and enclos- 

 es a greater area of blue fields, these not only crossing the wing but also 

 extending into the wide black marginal band on the primaries. The 

 orange spot on posterior margin of secondaries is larger, not marginal, 

 and has a narrow black line across its base which has the bulb scarcely

enlarged. Finally, the tails are narrow, not enlarged terminally. Fig. 5, f. 

 Below paler than above but with the markings repeated, but the triang- 

 ular orange markings seen on the hind wings of P. turnus, inside the 

 sub-marginal bands, are only slightly indicated. The light areas are 

 larger than above. Expanse from 3.50 to 4.50. 



Habitat, Europe, Asia, and as some entomologists affirm, it is found 

 in Western North America, from California, northAvard. Most authors 

 appear to think that only the following sub-species is found on our side 

 of the Pacific, and some regard oregonia as a sub-species of machaon.
