JS. punctatus, though generally distributed in England, appears to

NATUEAL HISTOEY OF LYGM-NA MGON. 
BT WILLIAM BUCKLEE. 
On the 31st July, 1867, Mr. C. Gr. Barrett, then at Haslemere, 
most kindly sent Mr. Hellins and myself some eggs of JEgon, which, by 
an ingenious contrivance, he had induced a $ to deposit on twigs of 
heather. 
Being in doubt as to the proper time for their hatching, I kept 
those I had in an ordinary room for daily inspection until the approach 
of winter. 
On the 23rd February, 1868, Mr. S. Hudson obligingly forwarded 
me three eggs, part of a small batch he had obtained from a ? during 
the previous summer, near Epworth, and with them the welcome intelli- 
gence that he had satisfied himself by experiment that the larvae were 
alive and stirring within the shells, and that he expected them shortly 
to hatch. 
I immediately removed all I had to a cooler place than they had 
previously been in, so as to retard their progress until something could 
be learned about the proper food. 
Considering the small size of this butterfly, the egg is rather large
