112 THE BUTTERFLIES OF THE WEST COAST 



well. Stella is a mountain butterfly, and is never seen on lowlands 

 near the coast, nor on any mountains near the salt water, but 

 always east of the high range of the Sierra Nevadas and the 

 Cascades ; at Spokane, Wash., I have found them abundant, fine, 

 large ones, more so than at any other place in all my travels. 



The males are spoken of as always white, yet the hind wings 

 are sometimes yellowed a little, and the females are always and 

 everywhere yellow. Stella is like Flora in that the females are 

 always yellow. The pattern of the marbling is different from that 

 of Sara, as you see by the plate.

Pima is from Southern Arizona, flying all over that vast desert 

 territory. It is almost always found on the hilltops, flitting about 

 the places where its food-plant is to be found, but it never flies 

 more than a little distance down the hillsides, and is never found 

 on the plains at the base of the hills ; in this peculiarity it simu- 

 lates the habits of some other butterflies, though the males of 

 many species are given to this method of diversion, to play with, 

 or to fight with, the males of the same or other species. 



As shown on the plate, both sexes are deeply yellow. The 

 sexes are very much alike, and after the specimens are dry and 

 shrunken and hard it is difficult to always tell which are males or 

 which females. That matter should be attended to while the 

 specimens are soft and fresh.

 Caliente, here figured, is unique, having no mate, although it 

 has stood in my cabinet for many years, all the while recognized 

 as a new species. I took it in the Colorado Desert of California, 

 far to the west of Yuma, in a locality difficult of access ; and in 

 those days when Pima was young I thought possibly it might be
