tliun cau be foniid in any other we have in Britain. " In its 

 beautiful flight," observes the late Rev. Revett Sheppard, a 

 most intelligent and scientific naturalist, " when it skims 

 aloft it rivals the Purple Emperor, which it strongly resem- 

 bles in appearance. It seems, howe\er, (unlike the latter), 

 to avoid the .sun-beams, for it frequents the glades of woods, 

 where it rapidly insinuates itself by the most beautiful evolu- 

 tions and placid flight, through the tall miderwood on each 

 side the glades, appearing and disappearing like so many 

 little fairies." It sometimes alights to .suck the blossoms of 

 the bramble. " There wa.s," says Ha worth, " an old Aure- 

 lian in London, so highly delighted at the inimitable flight 

 of Camilla, that long after he was unable to pur.sue her, he 

 used to go to the woods, and sft down on a stile, for the sole 

 purpose of feasting his eyes with her fascinating evolutions."
