358 Maternal Inheritance and Me7idelis7n 



moths derived from them were all normal in character. They, inbred, 

 gave 30 batches of eggs, of which, 12 batches were divoltine white, and 

 the remaining 18 all normal-coloured, which suggest to us that all the 

 batches in this generation would be all normal-coloured ones. 



Three divoltine white batches (Nos. 1*, 3 and 4) which were reared 

 in the summer gave three kinds of eggs, some batches being blue, as in 

 the parental blue, others blue shaded with a brown, which we called 

 " intermediate colour " and the rest normal-coloured batches. There 

 were no batches in which both blue and normal or intermediate forms 

 were found mi.xed. Respective figures obtained are given below ; 



Totals 47 165 204 416 



Of 416 batches derived from three parent batches, 47 were blue, 

 204 normal-coloured and the remainder intermediate. In the blue- 

 coloured eggs, we distinguished both light and dark-shaded ones. The 

 former we called " light blue " and the latter " dark blue." 



Five blue batches (Nos. 6, 14*, 24*, 25 and 28) laid by the mating 

 No. 20. 1 were reared in the spring of 1911. They oviposited, without 

 any exception, 251 batches of eggs, all of them being divoltine white. 



Eight white divoltine batches were reared in the same summer. 

 Both the light and dark blue series yielded again the antagonistic 

 characteristics as shewn below : 



Of the eight parent batches, four gave both blue and normal- 

 coloured batches, two all blue batches and the rest only normal-coloured 

 ones, the total number of batches produced by them being 91.
