THE CANADIAN- ENTOMOLOGIST. 3 



Chrysalis. — Length .8 inch ; shaped as in Group i of the genus ; 

 head case square, bevelled on either side about equally to the cross ridge ; 

 mesonotum prominent, carinated, followed by a deep and narrow depres- 

 sion ; the wing cases very prominent at outer ends ; abdomen conical, 

 with fine tubercles corresponding to those of the larva : color mottled 

 dark brown and black ; the wing cases gray-brown. The only chrysalis 

 I had died before imago. 



I have several times in previous years had eggs of Atlantis, and the 

 young larvae from them, but always had the ill luck to lose the latter dur- 

 ing the winter. But, 25th Aug., 1886, I received several eggs from Miss 

 Caroline G. Soule, then at Stowe, Vt., laid 21st and 22nd. They hatched 

 3rd Sept., and the larvae were placed in ice-house, and in October were 

 sent to Clifton Springs, New York, to go in the "Cooler" at the Sani- 

 tarium there. They came back to me 21st March, 1887, most of them 

 alive, and were laid on the tender leaves of a violet plant which had been 

 forced in anticipation of their coming. One larva passed 1st moult 15th 

 April, others two and three days later. The first to pass second moult 

 was on 25th April, two passed same 29th. On 9th May, one passed third 

 moult, the fourth 19th, the fifth 24th, and this larva pupated 3rd June, but 

 died during the pupal stage. The other larvae had died off from time to 

 time before 4th moult. So that I am not able to give the length of the 

 last stage to imago, but it is probably about 20 days, as in the allied 

 species. The habits of the larvae in confinement are in all respects like 

 those of Cybele. 



Atlantis is found over British America from Newfoundland and Anti- 

 costi to the Pacific. In the United States, over the mountainous parts of 

 New England, New York and Michigan.

Egg. — Shaped generally like the eggs of this Group, higher than 

 broad, about as 15 to 13, the number of ribs 30, conoidal, truncated, the 

 middle but little narrower than the base, the upper half sloping rapidly, 

 and convex ; about one third the ribs reach the summit, the rest end at
