110 THE BUTTERFLIES OF THE WEST COAST 



Flora is a mountain and northern form or variety of Reakirti, 

 and is characterized by a large size ; deeper black and more of it 

 on both upper and under sides ; by stronger colors of red and 

 green on both sides ; by black clusters of scales at the ends of the 

 nervures of hind wing on upper side; and by a zig-zag arrange- 

 ment or grouping of the blocks of marbling at the ends of the 

 nervures beneath. 



Flora is occasionally seen in the mountains of Southern Cali- 

 fornia at an elevation of 5,000 feet, but never in the southern 

 valleys ; while in Oregon and Washington it almost or wholly re- 

 places Reakirti, flying there at sea-level, and in great abundance, 

 and the specimens are larger and finer than those found in the 

 south. It is not now known how far north Flora flies ; I did not 

 see it at Wrangel at either time that I was there, but I believe that 

 it does fly there ; and probably in the interior, behind the moun- 

 tains, it goes much further north. 



The male of Flora is not yellowed at all, while the female is al- 

 ways strongly yellow, the lightest one I have ever seen is the figjure 

 bb, of the plate ; I give it to show the extreme, not as a typical 

 form.

Sara is the largest of the California Anthocharis. It flies most 

 plentifully on the immediate coast, and but less commonly in the 

 interior, at any point, disappearing entirely at no great distance 

 from the sea. Its habitat overlaps that of Reakirti, both species 

 being found at some common grovmds some miles inland : but in 

 those localities common to both, Sara does not appear in the spring 

 till a month later than Reakirti. Of all the species, Sara is unique 

 in that it sometimes is seen in the autumn, in October ; no other 

 form of Anthocharis is ever seen in the fall. 



Because the metropolis of each form is quite out of the range 

 of the other, I think they are separate species. If they were
