Notodontidae key

[Jim Taylor]

Hey, Folks,

I am in need of I.D. info on Notodontidae.  There should be about 50 species
in my area, SE Georgia (based on indicated ranges in Charlie Covell's book,
Forbes, etc.).  The keys in Forbes covers 29 species, and I have pictures
from another source of an additional 7.  That leaves about a dozen with no
key, no pic.  Anyone know of a reliable key for the Family - just my area or
the entire U.S.?
