Genus Papilio 
Early Stages .—The egg is outlined on p. 4, Fig. 3. It is green 
or bluish-green, quite smooth, with a few reddish spots in some 
specimens. The caterpillar feeds on a great variety of plants, but 
has a peculiar preference for the leaves of various species of wild 
cherry ( Cerasus ). The chrysalis is accurately portrayed in Plate 
VI, Figs. 1-4. 
The metropolis of this species seems to be the wooded forests 
of the Appalachian ranges at comparatively low levels. It abounds 
in southwestern Pennsylvania, the Virginias, the Carolinas, Ken¬ 
tucky, and Tennessee. I have often found as many as a dozen of 
these magnificent butterflies congregated on a moist spot on the 
banks of the Monongahela. At Berkeley Springs, in West Vir¬ 
ginia, I counted, one summer day, forty specimens hovering over 
the weeds and flowers in a small deserted field. The move¬ 
ments of the butterfly on the wing are bold and rapid. Its flight 
is dashing. Now aloft to the tops of the highest trees, now down 
in the shadows of the undergrowth, hither and thither it goes, 
often settling for a moment on some attractive flower, or staying 
its flight to quench its thirst on the sandy edge of a brook, and 
then away again over the fields and into the forests. In New 
England it is not very abundant, and in the Gulf States, while 
numerous, is still less common than about the head waters of the 
Ohio.

(Daunus). 
Butterfly .—This magnificent species, which is even larger 
than turnus (the figures in the plate are greatly reduced), re¬ 
sembles the preceding species in color and markings, but may at 
once be distinguished by the two tails on the hind wing and 
the projection of the lobe at the anal angle of this wing. It is 
found among the eastern valleys of the Rocky Mountain ranges, 
and descends into Mexico. In Arizona it is quite common. Ex¬ 
panse, 4.00-5.25 inches. 
Early Stages .—These have not yet been thoroughly studied, 
but what we know of them shows that the species is allied very 
closely to its immediate congeners, and the caterpillar feeds upon 
the same plants, principally Rosacece.

(Pilumnus).
