habitat of a species is responsible for its characters, and the more 

 minute the distinguishing features, the more necessary is a knowledge 

 of locality-conditions and range. 



1. Papilio rutulus Boisduval. 



This was a plentiful species in the well-watered canyons of the 

 Pacific slope of the mountains below 6,000 feet altitude. It was noted 

 in Mill Creek and Mountain Home Canyons in June, and all along 

 the Santa Ana up to within a mile of Big Meadows, 6,700 feet, from 

 June 10 to August 5. The follovving examples were preserved : Fish 

 Creek, at its confluence with the Santa Ana, 6,500 feet altitude, June 

 •20, T d", June 26, I c?^, July 3, 1 $,2 d'd, July 5, i $ ; near junc- 

 ture of South Fork with Santa Ana, 6,200 feet, July 2, 2 c?d^ ; Seven 

 Oaks, 5,100 feet, July 7, i c?- 



2. Papilio zolicaon Boisduval. 



This seemed to be a rare swallow-tail in the region worked, for 

 only one example was encountered. This was on the Santa Ana at 

 about 6,100 feet elevation, August 4, 1906. 



3. Papilio asterioides Reakirt. 



This almost black swallow-tail proved to be most common in the 

 Lower Transition sage belt along the upper Santa Ana, above 6,000 

 feet. It is a strong flyer and wandering individuals were met with up 

 through the black oak belt towards San Gorgonio Peak. One was 

 even seen flying over the triangulation station on the very summit of 

 San Bernardino Peak, 10,060 feet, July 12, 1905. 



This species, often supposed to be identical with indra of Reakirt, 

 is unquestionably distinct. It has been correctly described and figured 

 in Wright's recent book, only the specimens figured there are poor and 

 not quite representative of the average characters of the species. The 

 (S' of asterioides approaches pergamus quite closely. The female seems 

 to be very variable, one example approaching uniform blackness. 

 Specimens taken: Santa Ana Canyon, 6,100 feet, July 25, i ?, 

 6,500 feet, July 27, i $ ; South Fork Santa Ana, 6,200 feet, July 26, 

 I 9 ; Lost Creek, 6,400 feet, July 31, i ? ; Fish Creek, 6,500 feet, 

 June 20, 2 ? ?, I cT ; same, 6,700 feet, June 11, 1 (^. 



4. Pontia occiden talis (Reakirt) Scudder. 



One example from Seven Oaks, 5,100 feet, July 7, 1905, J*. 



5. Pontia protodice (Boisduval & Le Conte) Scudder. 



A fairly common species along the hotter north side of the Santa
