containing 25 males, 2 hippocoon, 4 trophonius, 2 leighi, and 

 22 cenea, of which 5 show strongly the effect of the parental 

 colouring. The collection also contains the trophonius parent, ^ 

 but not the offspring, of another family bred in 191 2 by 

 G. F. Leigh. The family contained 11 males, 2 hippocoo7i, 

 4 trophonius, 1 leighi, and 9 cenea. 



The last two synepigonic groups were the offspring of cenea 

 females. The ñrst ' was bred in 1902 from a cenea female 

 captured in copula, so that of this family — 7 males, 2 hippocoon, 

 and 6 cenea — both parents are present. The second family,' 

 bred in 1907, contains 15 males, i hippocoon, and 16 cenea. In 

 this last family the forewing spots of the cenea offspring are 

 somewhat unusually developed — a feature evidently inherited 

 from the female parent. It is also noteworthy that the depth 

 of the black markings of the male varies greatly in the different 

 families described above, and it seems quite clear that the extent 

 to which this characteristic is developed is also hereditary.* 



I trust that the series of specimens now before you conveys 

 some idea of the spirit in which we try to carry on our work. 



1 conclude, as I began, by bidding you a hearty welcome, 

 and by expressing the hope that you will always look back with 

 pleasure upon the week you are about to spend in Oxford. 



Mr. Eltringham announced that owing to the unfortunate 

 absence of the General Secretary, Dr. Malcolm Burr, the Secre- 

 tary's report could not be given. 



The President then announced the arrangement of the sections 

 and called on the Hon. N. Charles Rothschild to give his 

 paper entitled : 



Nature Reserves. 



Hon, N. Charles Rothschild said that the rapid advance 

 of civilisation rendered it urgently necessary to create reserves, 

 where the indigenous fauna and flora might flourish unmolested. 

 He explained the steps which had been taken in Great Britain 

 to achieve this purpose. A Society had recently been formed
