nated females were on the wing in the Wye Valley, and in 

 one sheltered spot 40 or 50 could be seen during the day. 

 My collector sent me 10 9 $ s and about a dozen c? c?s alive, 

 two of the former pi'oving to be virgins. 



" All these 9 ? s laid freely, and by June 20th the first 

 brood was emerging. I might mention here that on July 1st 

 I had 2 9 ? s that were captured in April still alive and 

 laying, and their offspring out and doing the same thing ; so 

 that the two broods (the hybernated 9 9s and the summer 

 brood) were on the wing simultaneously, and I can also say 

 that not a day lias passed between June 20th and K'ovember 

 1st without one or more specimens emerging in my cages ; 

 and to-day I have two living pupte remaining, thus suggesting 

 the possibility of taking C-album in ' the wild ' on any day 

 from March to November, providing the weather be warm 

 and sunny. 



"To resume — the first 65 specimens to emerge in June last 

 were all var. hutchinsoni. The 66 th showed a dark under 

 side and every other specimen (some 800 or so) were also like 

 it ; this clearly proving, as I think, that it is only the Jlrsi 

 feir eggs laid by the hybernated 9 in the spring which produce 

 the var. hutchinsoni. Of these I placed in my cage 12 9 9s 

 and 12 S 6s, and by 5 p.m. there were 12 pairs in cop. 

 Two or three days later when those with the dark under- 

 sides started to emerge freely, as a further trial I placed 

 3 9 9s and 3 c? <? s in the same cage. But they would not 

 even ' court,' nor would they have anything to do with the 

 S 6 hutchinsoni (still alive in the cage), although the latter 

 appeared quite willing to pair with them. They behaved 

 exactly like the 1905 specimens ; and to-day I have 3 of them 

 still alive hybernating, the other 3 having died oil for some 

 reason unknown. The last specimen to emerge from pupte 

 of the summer brood was on August 24th and the first from 

 the autumn brood was on x\ugust 18th, so that they overlapped 

 well, and I have had C-allnmi in all stages at the same time 

 during the greater part of the summer. 



"The results of the three separate years' experience thus 

 support the view that my deductions as to the life history of 

 this species ore well founded on fact."
