of the orifice close together again, and the pupa-skin 

 remains in the cocoon, which shows no change what- 

 ever in appearance. 



The pupa is brown in colour, nearly half an inch 

 long, stoutest at the thorax, and diminishing in the 

 ordinary way to the anal point, which ends in 

 a short spike. The old larva-skin, though much

 of the head and down the back, and was left in

That the latter part of my task has been accom-
