seasonal forms of the same parents they would both be most 

 abundant in the same localities common to both, which is far from 

 the truth ; the reverse is true, that neither form is abundant where 

 the other one is found at all.

This new form or variety of Sara is shown in typical style on 

 the plate. The apical black is sordid and indefinite, being reduced 

 by orange or yellow scales, and the orange is pale in color, and 

 lacks the sub-marginal black which in all other females of the 

 group separates the orange patch from the light sexual series of 

 spots near the margin, the series of sexual spots is yellow, while 

 the wings are white, and all the colors run into each other without 

 the ordinary definite separation. I therefore call it Mollis. 



I have taken Mollis several times each year, in Southern Cali- 

 fornia only, in the spring and in autumn also. It is simply a va- 

 riation of Sara, though I know not its limits, whether they be 

 seasonal, or climatic, or of habitat.

 This species has a pretty wide range, from Central California, 

 on the mountains at 7,000 feet elevation, north to British Colum- 

 bia, and how much further north it goes no man can tell. In the 

 southern parts of its range it is, as stated, alpine in its habitat, but 

 further north, as at the national boundary, it flies in the valleys as
