Life-History. 
The grub feeds internally upon the Tineid caterpillar. When 
’full grown it comes to the outside and spins on to the leaf an 
elliptical cocoon, attaching it by one end, It then pupates 
within this, The ichneumon fly leaves the cocoon by an opening 
at the unattached end, A fly was obtained on the 15th July. 
We have still to ascertain how long it spends in the larval or 
pupal stages, and how many generations it passes through in 
“the year.
