Transition. The last of July large numbers appeared about a flower- 

 ing pennyroyal (^Monardella lanceolata), and many were migrating up 

 the Santa Ana low among the brush clumps. Series secured : Fish 

 Creek, 6,500 feet, June 23 and 30, 3? ? ; same July 5, i cJ* ; Lost 

 Creek, 6,400 feet, July 31, i $ (an albino) ; South Fork Santa Ana, 

 6,200 feet, July 2, i c?, i ? ; south slope Sugarloaf, 6,700 feet, July 

 22, 2 d^c? ; Seven Oaks, July 7 and 9, 3 cf d^ ; Bluff Lake, 6,500 feet, 

 July 17, 21 and 28, 3 ? $. 



12. Eurema nicippe (Cramer) Hiibner. 



Several examples of this species were seen along the Santa Ana in . 

 the vicinity of Seven Oaks early in July, when a S was taken on the 

 7th at about 5,000 feet altitude. 



13. Argynnis semiramis Edwards. 



Perhaps the most abundantly represented species of the region. 

 Its center of abundance was plainly the Lower Transition zone where 

 it began to be common the last week of June. By July 20 most indi- 

 viduals were faded and battered, this process being no doubt helped 

 along by the frequent thunder-showers often accompanied by sleet or 

 hail. This butterfly was very active on warm days, and could only be 

 caught with ease when feeding on its chosen flowers. These included 

 the thistle (^Carduus ber?iardinus'), yerba santa {^Eriodictyon tricho- 

 calyx) and pennyroyal {^Monardella lanceolata). As somewhere in 

 the San Bernardino Mountains was the type-locality of Argynnis 

 semiramis, we secured specimens whenever opportunity afforded, with 

 the following results: Seven Oaks, 5,100 feet, July 7, 2 cf c? ; South 

 Fork Santa Ana, 6,200-6,400 feet, June 30-July 25, 14 d'd' ', Fish 

 Creek, 7,000 feet, June 30, 5 cJ'c?, 3 ? ? : Santa Ana, 6,500 feet, 

 July 25, I cf, I 9. 



14. Lemonias augusta (Edwards) Dyar. 



This very distinct but local species proved very numerous, especi- 

 ally in June, 1905, in the Upper Transition zone, where the blossom- 

 ing buckthorn {^Ceanothus cordulatus) constituted the chief attraction. 

 Fresh, bright individuals began to appear in numbers by June 15 and 

 by the last of the same month most examples looked pretty well 

 battered. The series secured shows remarkable constancy of char- 

 acters making this species one of the best-marked of the genus. 

 Although in our experience chiefly confined to Upper Transition, yet 

 suitable attractions brought individuals somewhat higher or lower, at
