silk which it spins for the purpose, and going to the edges to feed when disposed. 
As it increases in size, the leaf is somewhat drawn together, so that on the large 
leaves of the tulip tree it is not difficult to discover one of these larvae. It is slug¬ 
gish in habit, usually moving only when impelled by hunger. When full grown 
it stops feeding, and in course of about thirty-six hours changes color completely 
from green to brown, and at this stage deserts its tree and often travels, and 
that with considerable rapidity, many yards or rods until it finds a suitable 
place for its protection while in chrysalis. The butterfly emerges, in the neigh¬ 
borhood of Coalburgh, early in April, or if the weather has been favorable, in 
March, sometimes as early as the fifteenth day of that month. In Maine, Mr. 
Scudder says, it appears about the first of June. In Ontario, its time is the last 
of May. At Coalburgh, the males are to be seen, on any warm day of spring, 
gathered in groups of from half a dozen to fifty, by the edge of the water, in 
company with Papilios Ajax, Philenor , and later, Troilus. The females are not 
found in such situations, but they frequent the fruit trees then in bloom (as do 
the males in some degree), peach, apple, and above all the wild plum. Later in 
the season, both sexes abound on the red clover, then on the Asclepiades and 
thistles, and finally, at the close of the season, on the iron-weed, Vernonia. In 
the garden they delight in the lilacs, phloxes, and zinnias. Another plant, Cat- 
ananche bicolor, with its tall mullein-like flower stalks, is also very attractive to 
Turnus. 
On the wing the males are swift, and when alarmed, soar high in air or among 
the trees; but when settled in groups by the water, or feeding on flowers, they 
are fearless, and may be captured with the utmost ease. Mr. Scudder mentions 
the fact of sixty-nine Turnus being caught between the hands at one grasp. In 
the “ Canadian Entomologist,” V. p. 19, Mr. Couper relates as follows : “ I passed 
two months of the summer of 1871 on the Black River, about one hundred and 
forty miles north of Montreal, residing in a shanty on the road which follows the 
river through the mountains. Water in which pork had been parboiled was 
thrown out on the sandy lawn opposite the door, and I noticed that hundreds of 
Turnus frequented this spot during favorable weather, thrusting their tongues 
into the moistened sand, when the fluid absorbed, for which they seemed to have 
such an extraordinary liking, rendered them semi-intoxicated. I have seen 
them flying from all quarters direct for the shanty. Many of them, I believe, 
came from a distance of two miles at least.” 
The species of Papilio are subject to this sort of intoxication. There is a large 
patch of Asclepias purpurascens growing near my house, and all day long the 
flowers are thronged with butterflies,*the Papilios especially abounding; and 
many may be seen hanging motionless and for a long time, with heads and
