PAPILIO III, 
To obtain this missing link seemed impossible and year after year I had failed. 
Twice I had seen a female Telamonides deposit an egg and succeeding in hatching 
the larva therefrom. But in one instance it died before maturity and in the other, 
the larva from an egg deposited 11th May, 1867, gave Telamonides in April, 1868. 
1 had also succeeded in raising larvae from eggs seen to be deposited by Marcellus , 
but merely ascertained that the early summer brood of this form produced its like a 
few weeks later, without gaining any light as to the last brood of the season. The 
females would not lay their eggs in captivity, either in empty boxes or on cut 
branches of the food plant. 
In 1870, 1 determined to try the effect of confining the females with the grow- 
ing food plant, and 16th May, enclosed in a keg from which the heads had been 
removed and the upper end covered with gauze, a Telamonides. During the day it 
laid several eggs on the leaves. I was now obliged to leave home, and was absent 
two weeks. On returning I found six larvae only in the keg, of equal size and 
about half grown. Others had been hatched but had either escaped or had been 
destroyed. By 5th June, these larvae had stopped feeding, although but three 
weeks had elapsed since the female was enclosed. On 7th, they had fixed and 
by 8th had become chrysalids. Between 20th and 24th they had yielded imagos, 
2 $, 4 ?, all Marcellus. Time from laying egg to imago 85 days. 
On 1st June, I enclosed three Telamonides, and, on 2d, had obtained from them 
37 eggs. From these, on 3d July, 2 ? Marcellus emerged and others followed till 
9th, when I had 12 $, 10 $, all Marcellus. Time from laying of egg to imago 33 
days. One chrysalis from this brood went over the season, and 1st April, 1871, 
yielded $ Telamonides. 
On 7th June, I enclosed a Marcellus and from it, on 23d, had five mature 
larvee. On 4th July, 1 $ Marcellus emerged, on 9th 3 $. Time from laying of 
egg to imago 27 days. One chrysalis went over the season and was alive 1st April 
1871, but died before yielding imago. 
On 1st July, I enclosed a Marcellus, which in point of time would be of the 
second brood in succession from Telamonides. By 18th, there were eighteen larvae 
living from which resulted fourteen chrysalids. On 31st, the imagos began to ap- 
pear and by 3d August, there were 4 <?, 3 $, all Marcellus. Time 30 days. Seven 
of this lot of chrysalids passed their period and one of them gave ? Marcellus, 
on 28th August, six weeks afterwards. The other six went over the season and 
were living in the following February, but unfortunately were destroyed by fire 
about the end of that month. 
Late in August, from eggs of Marcellus obtained in same way, I had two 
larvae which matured 1 2th Sept. One of these soon after yielded Marcellus, the 
other went over the season but was lost with those before mentioned.
