I give a diagnosis of H. lividus, in order to show tlie characters 

 of the two species.

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

 be not so common as H. lividus. I have specimens from Whittlesea, 

 Mere, Cambridge, London, and the New Forest.*

NATURAL HISTORY OF LTCJENA MGON. 

 BY WILLIAM BUCKLES. 



On the 31st July, 1867, Mr. C. G-. Barrett, then at Haslemere, 

 most kindly sent Mr. Hellins and myself some eggs of JEgon, which, b}^ 

 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
