75 
minute white dots. On the first segment is a yellow fold, and on 
each side of the fourth segment an eye-like yellow spot surrounded 
by a black ring; on the hinder part of the fifth segment a transverse 
yellow fold; faint bluish dots on each side of the fifth and hinder 
segments; the head, underside and legs pink. Length, two inches 
or over. 
Found in June and July, feeding on the leaves of Apple-thorn, 
wild and cultivated Cherry-trees, folding them in the same manner 
as the larva of the Troilus Butterfly. 
One found last year in May went into pupa state May 23. 
Papilio chresphontes, Cram. The Chresphontes or Thoas Butterfly. 
When first hatched the larva is not more than one-tenth of an 
inch in length, and apparently entirely black, or brownish-black; 
in a day or two a few yellowish-white spots appear on the back; as 
the worm grows these spots seem to spread or come together until 
they finally, when the caterpillar is full grown, form two large 
white patches; the anterior one is lozenge*shaped and extends 
across the back and a part of the sides, one angle reaching to the 
first pair of abdominal feet. The other white patch covers the 
posterior part of the back, and is marked on its anterior side with 
brown spots; the space between these two patches is dark brown. 
A whitish longitudinal stripe extends from the head on each side 
across the first four segments; between these two stripes there is a 
large brown patch marked by large brownish-black spots; behind 
this brown patch occur the large white ones before described; the 
underside of the body and the feet are brown. The first segments 
behind the head are enlarged. Length, when full grown, a little 
more than two inches. 
Found June 1 on a shrub of Prickly-ash, and changed to the 
chrysalis form June 17; another, taken October 10, changed the 
17th.
