THE PALI''. SWALLOW TAIL is abundant ihiou-houL the 

 state from early spring to mid summci'. h Is an occasional cap- 

 ture in the lowlands, but is more at home in the canyons and up- 

 land meadows of our mountain ranges, where one may often 

 capture it in great numbers as it sips the nectar of thistles, or 

 drinks from the moist sands at the side of mountain streams. 

 Felder has distinguished a form w'hich he has called albanus, "of 

 smaller size and clearer white ground color; tails long and nar- 

 rower: marginal spots nearer the margin.'' The name seems 

 hardly worthy of retention. 



The lar\-al food plants include Rhamnus calijornla (California 

 wild coffee).

EARLY STAGES OF EUPHYDRYAS SIERRA, WRIGHT 



{Illustrated by the Author.) 



During a recent expedition into the Yosemite region I was 

 fortunate enough to secure two specimens of the larva of Euphy- 

 dryas sierra, which were carried through the pupal stage, and one 

 of which emerged. 



The lar\-3e w^ere observed by Dr. Carolyn Comstock on w'hat 

 we believe was a species of Montia. They pupated without fur- 

 ther feeding, on July 2nd, and one emerged on July 13th. The 

 following notes were made of the larvae and pupae.
