In the following keys to the genera, that part dealing with the Papilionatae 

 has been made purely artificial in many respects. In the construction of the 

 keys to both genera and species suggestions have been taken from the previously 

 published works of various authors, modified by the forms dealt with in the 

 following enumeration. In these keys only Philippine representatives have been 

 taken into consideration.
