156 THE BUTTERFLIES OF THE WEST COAST 



Gabbi is a southern species, being found in southern California 

 and in the southern parts of Nevada, and Utah, and in Arizona. 

 It is the first one of the three "pearly spots," the light spots on the 

 underside of hind wing being so lustrous that they might almost 

 be called silver. This pearly luster is not properly shown on the 

 plate, as it is one of those things that cannot be caught by the 

 photographic process. 



Gabbi is an early spring bird, very slow and gentle in flight, 

 and stopping often to rest, alighting on the ground and waving 

 its wings wide open, as if enjoying itself greatly. It frequents 

 the foothills and the lower canyons and open valleys, but is never 

 seen on the hilltops or in exposed places.

 This species is of more northern habitat than Gabbi ; it is not 

 seen south of the Tehachapi Mountains. I have taken it on the 

 Tehachapi, and the Greenhorns, and thence northward to the 

 plains of Eastern Washington ; and as the conditions hold good, 

 it is likely to go far north into the provinces of Canada at the 

 eastern base of the Rocky Mountains.

 Palla is a still more northern species than the last ; it flies from 

 the mountains of Central California through all the intermediate 

 countries to Alaska at St. Michaels. The spots of underside are 

 less pearly than the two preceding species. It is altogether a 

 mountain flyer and is not seen in the plains and valleys of the 

 States, but, of course, it flies on the plains at the far north.
