NortE. — In all the descripuons in the following pages the wing-expanse is given according to 
the extreme tip-to-tip measurement. The adoption of the old continental method of taking the average 
expanse of set specimens resulted in certain inconsistencies and inaccuracies which far more than 
outweighed any possible convenience.
