 out of 24 genera forming Table II., 5 are described by Moore as 

 protected and 3 as exhibiting mimicry ; whereas out of all the 

 '600 genera described only 41 are mentioned as either protected 

 or mimicking. ISTo reason can be given why the other 16 genera 

 (for the most part belonging to the Pieridaa) present a conspicuous 

 pattern*. It is, hoAvever, noteworthy that the sexes arealike, 

 with the exception of Enrymus and Chrysophanas, where the 

 pattern is confined to the male. Several of the genera are 

 amongst the commonest of butterflies, and at certain times collect 



* The Pierinse and Coliinae are considered by some observers to be " protected " 

 insects.
