GENUS ANTHOCHARIS 107 



rator at the Academy of Sciences in San Francisco many years 

 ago, date not noted, and he had no data for it, as he rarely noted 

 down data at that time. I had at that early date noted that there 

 was a desert species unrecognized, being in those days often on 

 the desert, and so I got this from him, to follow it up. 



6i. Anthocharis Genutia. 



Plate VII ; Figures 6i, male ; b, female. 

 This is the Anthocharis of the Eastern States, the only form 

 that is found on that coast. It is inserted here just for compari- 

 son, and to show the difference between the eastern and western 

 species. The females of the eastern kind never have any orange 

 on the tips ; one might almost class them as belonging to the genus 

 Euchloe, and the males Anthocharis. In Euchloe neither sex has 

 orange on the tips of the wings, and in Anthocharis both sexes 

 have orange tips, so that this eastern species appears to belong to 

 both genera. 



62. Anthocharis Reakirti.

 This is about the first butterfly to appear in spring on the west 

 coast ; Cethura, Morrisoni, and Deserti are on the wing at about 

 the same time, but Sara does not appear till a full month after- 

 wards. Reakirti lives on the plains and in the hills of the interior, 

 or not on the immediate sea coast, and flies sometimes up the 

 mountain sides to an altitude of 4,000 feet. It is found from 

 Mexico to Oregon. The males are occasionally yellowed a little, 

 chiefly on the hind wings, and more of the females are yellowed, 

 say to fifteen or twenty per cent, and some are deeply yellowed. 

 Some yellowed ones of both sexes are figured on the plate. All
