I gave it as my opinion that it was not desirable to separate Pyrrhopyga from 

 Erycides because of the difference of their antenna). I would be very glad now

The diurnal Lepidoptera have of late years been visited by an intolerable 

 plague of old and new generic names. On going through a list of butterflies a 

 few years ago, any one might comprehend its contents at a glance, now it is 

 necessary to go to a dictionary to interpret them. 



Before bidding farewell to all those with whom the work has brought me 

 into most agreeable contact, and some of these have become valued friends, I 

 must express my thanks to my generous publisher, Mr. J. Van Voorst, and to 

 Mr. Charles Standish for his careful and conscientious colouring of the plates.
