Then on the card make a description as full as possible of the 

 larva, noting shape, color, stripes and spots on the body, color 

 and spots (if any) on head, thoracic shield and legs. State its 

 habits, whether it crumples, folds or curls leaf, or lives in 

 stems or fruit, and anything that seems interesting about it. 



If you can observe date of pupation, make record of it and, 

 of course, when moth emerges do the same. 



Put this same number on everything that issues from this 

 particular jar. There will be Dipterous and Hymenopterous 

 parasites; it is just as likely that they are unknown, or at

 be of value. The pupa and cocoon should also be preserved, 

 and if a sample of the twisted leaf, etc., can be saved, both 

 should bear the same breeding number. It is well to put the 

 initial of your name in front of this series of numbers, as K. 

 427, to distinguish your bred material from other specimens 

 in your collection that may happen to have miscellaneous num- 

 bers on them.
