why won't stupid pini eclose?

[Liz Day]

Hi listers,

I had 3 Eacles imperialis pini pupae that overwintered in my frij.  They 
were kept with a regal pupa, some regular imperials, and some poplar
sphinx.  In spring everyone was put outdoors in a flowerpot filled with
peat moss.  Later, everyone proceeded to eclose at roughly the normal
time.  One of the pini hatched out about 3-4 weeks ago.  

The remaining two pini are very much alive and squirming, but have not
emerged.  Frankly, I'm getting impatient.  I want them to get it over
with, so I can have my porch back!   

Does anyone have a clue either what is wrong, or what to do?  I'd hate for
them to decide they feel like overwintering again.  :-(   :-(

Thanks,
