MOTHS AND BUTTERFLIES. 
A butterfly which looks as if it had in part borrowed its shape 
from Papilio turnus and its colors from our next species, Papilio 
ajax , is Papilio eurymedon. This insect belongs to the western half 
of the continent and is plentiful along the eastern base of the Sierra 
Nevada in June and July. The caterpillar resembles that of Papilio 
turnus. 
Papilio ajax. Early Spring Form. 
Having little similarity to, and therefore easily distinguished 
from our other species of Papilio , is Papilio ajax. Like so many of 
this fine family it is an exceedingly beautiful insect. Several varie¬ 
ties of the butterfly are recognized b}^ naturalists, each having its 
own name, which were at one time supposed to be distinct species. 
It has been discovered, however, by careful observation that all the 
varieties may spring from the same set of eggs, those which emerge 
from the chrysalides early being the smaller and lighter and having 
short tails to the hindermost wings, those which hatch later being 
somewhat larger and darker, with longer tails, and those which are 
developed from the eggs and larvae the same season being the larger, 
with wide bands of black and having long tails. The accompanying 
figures will give a clear idea of the differences between the varieties.
