$, Telamonides. On 23d June, full three weeks after its period came another 
$ Marcellus and a second followed on the 12th July. Of the other chrysalids seven 
are living at this date (15th October) . In these cases the eggs of each lot were 
unusually long in hatching, 8 days, and the time from laying of egg to imago of 
the first was 51 days and of the second 44. 
On 23d May, I enclosed another Walshii with the usual result. The eggs be- 
gan to hatch on 28th, five days. From these, on 13th June, I had thirty-two 
chrysalids. The first imago appeared 24th June. Time from laying of eggs thirty- 
one days. By 30th, 10 $, 7 ?, Marcellus had emerged and 14 chrysalids are living 
at this date (15th October). 
On 27th May, I enclosed a Telamonides that had but a slight trace of 
white at sides of the tail near the tip and in this respect approached Walshii much 
more nearly than I had before observed in that variety, though otherwise it was 
distinctly Telamonides. From this I obtained many eggs which hatched on 31st 
and gave nineteen larvae. These were peculiar in that they were all remark- 
ably black, and several entirely so, without even the usual white line on fourth 
segment. The butterflies began to emerge on the 28th, and there resulted seven 
Marcellus. Time from laying of egg 32 days. At this date 15th October ten 
chrysalids are living. 
From another Telamonides enclosed 28th May, resulted 2 $, 2 ? Marcellus on 
3d and 4th July, and six chrysalids are still living (15th October.) 
On 1st and 4th June, I enclosed several Marcellus. These laid scores of eggs 
and in due time I had 123 larvae, and from them on 2d July, seventy-six chrys- 
alids. On the 5th, the imagos began to appear and by 13th, 21 $, 15 ?, had emerged, 
all Marcellus. At this date, (15th October) 40 chrysalids have long passed their 
period. Time 34 days. 
Finally, on 29th July, I enclosed a Marcellus , and obtained therefrom forty- 
two chrysalids. Of these, thirteen produced Marcellus 4 £, 9? , and twenty-nine go 
over the season. 
It will be noticed that a large percentage of the chrysalids of nearly every 
brood pass the winter, the proportion seeming to increase as the broods succeed each 
other. Of the first brood of Walshii, of 67 chrysalids, 7 passed over ; of the second 
of 39 chrysalids, 14; of the first of Telamonides, of 17 chrysalids 10; of the second 
of Telamonides of 10 chrysalids, 6 ; of the first brood of Marcellus, of 76 chrys- 
alids, 40; of the second brood of Marcellus, of 42 chrysalids, 29. 
The summing up therefore of this whole series of observations is this ; Walshii 
produces Walshii, Telamonides and Marcellus, the same season; Telamonides pro- 
duces Marcellus the same season and its own type in the Spring; Marcellus pro-
