March, 1907.] GrINNELL & GrINNELL : CALIFORNIA BUTTERFLIFS. 41 



Ana in the Upper Austral and Lower Transition zones. Noted from 

 Seven Oaks, 5,100 feet, nearly to Big Meadows, 6,700 feet. Two 

 specimens: Santa Ana, opposite mouth of Fish Creek, 6,500 feet, 

 June 19, J", July 5, ?. 



6. Pontia rapae (Linnaeus) Scudder. 



One example — Santa Ana near mouth of Fish Creek, July 5, ?. 



7. Nathalis iole Boisduval. 



This was a common species in warm open stretches along the upper 

 Santa Ana. It was not seen outside of the belt of sage {Artemisia 

 tridentata) among the clumps of which it was difficult to see when in 

 flight. It seems to be a local butterfly everywhere, and somewhat 

 erratic in times of appearance. Examples obtained : Santa Ana, oppo- 

 site mouth of South Fork, 6,200 feet, July 2, i r? ; Santa Ana, oppo- 

 site mouth of Fish Creek, 6,500 feet, June 20, 22 and 26, 3 d^cf ; 

 same, July 5, 2 S'S' ; Fish Creek, 7,000 feet, June 17, i c?. 



8. Callidryas eubule (Linnaeus) Boisduval & Le Conte. 



Detected but once — a d^ taken on the Santa Ana near the mouth 

 of Fish Creek, 6,500, feet, June 23, 1905. It is rather surprising to 

 find this species at such an altitude ; for it is ordinarily noted chiefly 

 around parks and gardens in the thickly settled and cultivated valleys 

 of southern California.

One specimen — Fish Creek, 6,500 feet, June 19, d^. 



10. Zerene eurydice (Boisduval) Scudder. 



This was a common and conspicuous species about the head of the 

 Santa Ana, ranging up through Upper Transition. A shrub growing 

 abundantly in the black oak belt {Amorpha califoniica^ was particu- 

 larly attractive to the 9 ? ; while the cJ*d^ congregated on clover 

 patches and wet sand along the streams, sometimes as many as five 

 alighted or fluttering close together. Two of the 9 ? secured are of 

 the so-called "variety amorphce'''' which is very obviously but an in- 

 individual variant of eurydice. Twelve specimens: Fish Creek, 

 6,500 feet, July 5, 10 and 23, i d^, 3 $ 9 ; same, 7,000 feet, June 

 30, 2 9 9; South Fork, Santa Ana, 6,200 feet, July 2, 2 d^c? ; same, 

 6,400 feet, July 20, 2 9 9; same, 7,500 feet, i 9 ; Seven Oaks, 5,100 

 feet, June 27, i 9 . 



11. Eurymus eurytheme (Boisduval) Scudder. 



A common species on cienegas and in open woods up through
