LETTERS ON ENTOMOLOGY. 31 
ing year, one Sunday, a little before sunset, I 
was enjoying a stroll, with a friend, at a greater 
distance from the river, when, in a field by the 
road side, the same pleasing scene was renewed, 
but in a style of still greater magnificence ; for, 
from some cause in the atmosphere, the insects 
at a distance looked much larger than they really 
were. The choral dances consisted principally 
of ephemerae, but there were also some of chi- 
ronomi ; the former, however, being most con- 
spicuous, attracted our chief attention— alter-

scarcely resembled any thing material — they re- 
minded us of angels and glorified spirits drink- 
ing life and joy in the effulgence of the Divine 
favour." 
The bard of Twickenham, from the terms in 
which the beautiful description of his sylphs is 
conceived in The Rape of the Lock, seems to have 
witnessed the pleasing scene here described : 
" Some to the sun their insect wings unfold, 
Waft on the breeze, or sink in clouds of gold ; 
Transparent forms, too fine for mortal sight, 
Their fluid bodies half dissolved in light ; 
Loose to the wind their airy garments flew, 
Thin glittering texture of the filmy dew,
