MISCELLANEOUS NOTES. 



Rearing Butterflies erom the Egg. — In the last number of the 

 Canadian Entomologist I mentioned that I had succeeded in inducing 

 females of P. ajax to deposit eggs, by enclosing them in a keg placed over 

 the growing food-plant — the paw-paw. The first female enclosed on May 16th 

 laid a number of eggs, and another female was enclosed in the same keg on 

 the 17th. I was obliged to leave home for some days, and returned on June 

 1st, when I found but six larvas in the keg. These had hatched and attained 

 a length of three-fourths of an inch within sixteen days. On the 5th of 

 June the larvae were mature and had stopped feeding ; the whole time from 

 the laying of the eggs being but three weeks. On the 20th one % Marcellus 

 emerged; on the 21st a 9 Marcellus, and by the 23rd four others emerged, 

 all Marcellus. 



On the 1st of June I put three 9 Ajax into another keg ; by the 2nd 37 

 eggs were deposited. These began to hatch on the 6th. From this lot I 

 obtained 21 chrysalids, which began to give imagos by 3rd of July. From 

 them I obtained 12 ^ and 10 9 , all Marcellus. 



On June 7th I shut up a 9 Marcellus, the first I had noticed flying this 

 year. By the 23rd I had five larvae from this lot. The imagos began to 

 appear on the 4th of July, and gave three 9 and^one % , all Marcellus, not 

 distinguishable from those produced from the eggs of Ajax as above. 



So that the question of the identity of Ajax and Marcellus may be 

 regarded as settled. 



I have had no difficulty, by some means, in inducing other species to 

 deposit eggs. On a young tulip tree I placed two black females of Turnus 

 (Glaucus), and have now several larvae growing as the result. I have also 

 raised two broods of C. Philodicc, and the Nisoniades lycidas, and JV. 

 pylades, Scudder.
