quadrifids, and reach their maxiniuni development in the Deltoid series where 

 secondary sexual modifications furnish excellent bases for generic and specific 

 divisions. 



The quadrifids are broken up into a larger number of smaller series, 

 and some of these contain very few species in our fauna ; in California some 

 are not represented at all. 



For convenience, the table given by Sir George F. Hampson, in the 

 4th Volume of the Catalogue of the Lepidoptera Phaljenae in the British 

 Museum is here repeated with a very few changes in the sub-family terms. It 

 should be understood that I do not consider all these as really sub-families, nor 

 are the divisions always sharply marked ; but for convenience the table is 

 better than any other that I know and it will work in the vast majority of cases.
