inimitable flight of Camillia, that long after he was unable to pursue her, he 

 used to go to the woods, and sit down on a stile, for the sole purpose of 

 feasting his eyes with her fascinating evolutions." 



Mr. Haworth goes on to say " The following admirable lines of Pope, 

 Virgil, and Dryden, although not all of them exactly necessary, to elucidate 

 this subject, 1 cannot refrain from transcribing in this place " : 



" These equal syllables alone require, 



Tho' oft the ear the open vowels tire, 



While expletives their feeble aid do join, 



And ten low words oft creep in one dull line, 



Soft is the strain when zephyr gently blows, 



And the smooth stream in smoother numbers flows ; 



But when loud billows lash the sounding shore, 



The hoarse rough verse should like the torrent roar ; 



When Ajax strives some rock's vast weight to throw, 



The line too labours, and the words move slow ; 



Not so when swift Camilla scours the plain, 



Flies o'er the unbending corn, and skims along main." 



POPE. 

 " Vel mare pejr medium fluctu suspensa tumenti, 



Ferret iter, celeres nee tingeret sequare plantas." 



VIRGIL. 

 " She swept the seas, and, as she skimm'd along, 



Her flying feet unbathed on billows hung." 



DRYDEN. 



" In its beautiful flight/' observes the Rev. Revett Sheppard, M.A. (of 

 Wrabness,in Essex, a most intelligent and scientific naturalist, in Miss Jermyn's 

 " Butterfly Collectors' Vade Mecum," second edition, published in 1837), 

 " when it skims aloft it rivals the Purple Emperor, which it strongly re- 

 sembles in appearance. It seems, however, unlike the latter, to avoid the 

 sunbeams, for it frequents the glades of woods, where it rapidly insinuates 

 itself by the most beautiful evolutions and placid flight through the tall 

 underwood on each side the glades, appearing and disappearing like so 

 many little fairies." 



Mr. Newman, in his " British Butterflies," 1871. observes that we are in- 

 debted to Mr. Hunter for the first description of the caterpillar and chrysalis 

 of the White Admiral from English specimens; it was published in the 

 "Zoologist," for 1851. The descriptions by Curtis and other British authors, 

 copied from Hubner, refer to another species (Camilla) not yet found in 

 Britain ; the error originated in the fact that Haworth applied the name 

 Camilla by mistake to our English insect. A second and much more detailed 

 description of the caterpillar, by M. de la Chaumettee, is published in the 

 same volume, and a description of the caterpillar of Camilla is given to show
