quadrifids, and reach their maximum development in the Dehoid 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 \'olunie of the Catalogue of the Lepidoptera PhaL-enpe 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.
