PAPILIO III. 



1?, Tdamonides. On 23d June, full three weeks after its period came another 

 ? Mnrcellus and a second followed on the l2th Jidy. Of the other chry.salids seven 

 are living at this date (loth 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 Wahhil 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. Tiipe from laying of eggs thirty- 

 one days. By 30th, 10 (?, 7 2, Marcellus had emerged and 14 chrysalids are living 

 at this date (loth 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 loth October ten 

 chrysalids are living. 



From another Telamonides enclosed 28th May, resulted 2 c?, 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 o^ 3Iarcellus, 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-
