There are 180 butterflies recorded as native to California; not 
including polymorphic forms, nor any loeal examples breeding 
true to type and ealled races or subspecies. Nor is there any 
consideration taken of real varieties or sports. Out of these 180 
species thus recorded the list for Southern California numbers 
107, and this list will be increased yearly as the families of the 
Lycenide and Hesperidea are investigated.
