CaHfornica inhabits the grassy foothills where the pine and 

 oak trees are scattered scantily about, and the soil is covered 

 with scanty grasses, which, at the time that the butterfly is in 

 flight are dried up and dead for that year. The butterflies alight 

 upon spots of dried ground or among the dead herbage, as stated 

 under the genus heading. 



The male here figured was taken by me in the Klamath country, 

 and was sent to Mr. W. H. Edwards, and returned named "Cali- 

 fomica," being one among many so returned. 



This is not one of the "stranded butterflies," and is never seen 

 on cold or alpine heights, but frequents warm and sheltered places. 



The determination of this species is chiefly by the under side, 

 the striations being even, smooth, not contrasting.

 Iduna inhabits the evergreen forests of Northwestern Califor- 

 nia. They never eat nor drink, and I know from personal obser- 

 vation that the flight lasts but a week. The male Iduna has habits 

 that remind one of the Limenitis ; they sail along with horizontal 

 wings, and as they go they flicker their wings with a twitching 

 flutter to keep up their motion, and then sail again on horizontal 

 wings. The male Iduna has a fancy for alighting on the end of a 

 twig, and sitting there with the wings out flat like a Limenitis; 

 when thus on the watch, they will fly in alarm if the butterfly-
