Caterpillars, previous to their going 
into chryfalis, generally lofe the bril- 
liancy of their colours, and many of them 
rove about for a confiderable time. 
After remaining in their chryfalis 
{late till near the time of their coming 
forth, fuch as are inclofed in a hard 
cafe or fpinning, as the Phalaena, 
Vinula, Pufs Moth, Phalasna Quer- 
cus, &c. are to be carefully freed 
from it ; as the aperture which the 
Infeft naturally makes, is often too 
narrow for it to pafs out without con- 
hderably injuring its plumage. The 
opening will be befr made by cut- 
ting off the larged: extremity of the 
cafe, taking care not to wound the in- 
clofed Pupa or Chryfalis.
