most grossy leaves. 
The description of this insect will appear

enemies, it is necessary to describe it at full length. 
I have therefore given as clear a description 
as I am able to do, and should any one doubt 
the assertion, or be wishful to ascertain the truth, 
it may be readily done by putting a few of the

half filled with earth, at the same time putting 
a few twig ends of the Berry bush, furnished 
with leaves, to serve them to feed on a few days, 
in case they should not be ready for their change. 
Cover the pot over with a piece of canvas or cloth, 
tied round the pot, to prevent them or the Fly

ascertain when the emago comes forth. 
In respect to the injuries produced by the
