55. Pieris occidentalis Reak. 



Rather common everywhere in July and August. Mr. Grin- 

 nell has a male of the variety calyce Edw., taken July 25, 1907, 

 near Glen Alpine Springs (6,540 ft.), and Wright reports this 

 variety from Tahoe. 



56. Pieris rapae L. 



Quite common in the canyon at Deer Park during July and 



August. 



57. Anthocharis ausonides Bdv. 



This species occurs in some numbers from June until the last 

 of July, and at least to 9,000 feet elevation. The individuals 

 average smaller than those taken about San Francisco Bay. 



58. Anthocharis sara var. reakirtii Edw. 



A rather common butterfly below 8,500 feet elevation; flies 

 from the middle of May until the last of July. The specimens 

 in this region are of the form Stella Edw., in which the females 

 are yellow instead of white. The males also have a yellowish 

 tinge. The larvae of this and the preceding species feed on a 

 number of cruciferous plants, particularly Arabis glabra (L. ) 

 Bruh., A. lyallii Wats., and A. duriuscula Greene. 



59. Colias eurytheme Bdv. 



This occurs all summer and is found in proper season at all 

 elevations, the commonest in the Canadian Zone. I took the 

 variety eriphyle Edw. at Deer Park, in July and August, below 

 7,000 feet elevation. 



GO. Parnassius clodius Men. 



This species is common at the lower elevations from early 

 June -until August, and probably later. The variety menetriesii 

 Hy. Edw. also occurs. I have several specimens with the spots 

 pinkish yellow, which would bring them near the variety altan- 

 rus Dyar. They are worn specimens, however, and may have 

 faded. 



Gl. Parnassius smintheus Db. & Hew. 



Wright reports the synonym sayii Edw., from "near Lake 

 Tahoe." The variety behrii Edw. is not rare at altitudes of
