PAPILIO IIL 



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, 18G7, gave Telamonides in April, 18G8. 



1 had also succeeded in raising larvae from eggs seen to be deposited by Ilarcellus, 

 but merely ascertained that the early summer brood of this form jsroduced 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 ca23tivity, 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 larviB only in the keg, of equal size and 

 about half grown. Otliers had been hatched but had either escaped or had been 

 destroyed. By 5th June, these larvoB had stopped faeding, although but three 

 weeks liad elapsed since the female was enclosed. On 7th, they had fixed and 

 by 8th had become chrysalids. Between 20th and 24th they had yielded images, 



2 c?, 4 5, all 3Iarcellus. Time from laying egg to imago 35 days. 



On 1st June, I enclosed three Telamonides, and, on 2d, had obtained from them 

 37 eggs. From these, on 3d July, 2 2 Marcellus emerged and others followed till 

 9th, when I had 12 $, 10 S, 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 

 larvfe. On 4th July, 1 $ Marcellus emerged, on i)th 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 yiekUng imago. 



On 1st July, I enclosed a Marcellus, which in point of time would be of the 

 second bi-ood in succession from Telamonides. By 18th, there were eighteen larvte 

 living from which resulted fourteen chrysalids. On 31st, the images began to ajj- 

 jiear and by 3d August, there were 4 <?, 3 2, all Marcellus. Time 30 days. Seven 

 of this lot of chrysalids passed their period and one of them gave ? JIarcellus, 

 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 fii'e 

 about the end of that month. 



Late in August, from eggs of Marcellus obtained in same way, I had two 

 larva:- which matured 12th Sept. One of these soon after yielded Marcellus, the 

 other went over the season but was lost with those before mentioned.
