38. Rusticus enoptes (Boisduval) Scudder. 



Three examples: c?cf, Fish Creek, 6,500 feet, June 23, 1905. 

 These specimens agree with the figure in Wright's recent book, and 

 are no doubt distinct from aciiion and other species, but we are quite 

 sure true enoptes is a different thing. The problem remains to be 

 worked out. 



39. Rusticus acmon (Doubleday & Hewiston) Scudder. 



A fairly common species widely distributed, as follows : Santa 

 Ana, 6,200-6,500 feet, June 19-July 26, 6 S'S', i ? ; South Fork, 

 6,400 feet, July 20, i d^ ; cienega at head of South Fork, 8,500 feet, 

 June 28, 2 c?c? ; cienega on south slope of Sugarloaf, 6,700 feet, July 

 22, I ?. 



40. Hemiargus isola (Reakirt) Scudder. 



Two examples: Fish Creek, 6,500 feet, June 23, i cJ* ; South 

 Fork Santa Ana, 7,000 feet, June 27, i ?'. 



41. Leptotes marina (Reakirt) Scudder. 



Seen sparingly in the black oak belt, especially around a shrub 

 {Amorpha calif ornica') occurring only in that belt. Fish Creek, 6,500 

 feet, June 19, xS' ', South Fork Santa Ana, 7^000 feet, June 27, irj*. 



42. Copaeodes Candida Wright. 



Two specimens: Santa Ana, 6,500 feet, July 25, 1906, ir? ; near 

 mouth of Fish Creek, 6,500 feet, June 19, 1905, i 9. Wright records 

 this from the San Bernardino Valley, but it evidently occurs also to 

 quite an elevation in the mountains. 



43. Ochlodes agricola (Boisduval) Scudder. 



Three rj^.d^. Fish Creek, 6,500 feet, June 19, 1905. 



44. Thymelicus sylvanoides (Boisduval) Dyar. 



Fish Creek, 6,500 feet, June 18, id^. 



45. Erynnis Columbia (Scudder) Scudder. 



This was by far the most abundant skipper in the region, ranging 

 up into the Canadian zone about cienegas. The greatest numbers ap- 

 peared to occur in Lower Transition, where on beds of clover along 

 streams it convened in the hottest part of the day along with the blues. 

 It was numerous also in the open woods of the black oak belt flying 

 about and alighting upon almost any sort of herbage. The thistles 

 were favored more than any other flower, though yerba santa was a 

 close second. 



There is considerable variation in our series in the color of the 

 under sides of the secondaries and in size, but all seem to belong to the 

 same species.
