THE LEPIDOPTERA OF THE SOUTH-EASTERN DISTRICT OF LONDON. 233 



Society, 1878), noting that the differentiation of the colours of the white 

 L. boscana and the dark grey L. Rcabrana appears to be a seasonal 

 variation in response to their environment, concealment during bright 

 summer weather being effected by the insect being then produced of a 

 silvery-grey colour, and, when the dulness of autumn and the wet have 

 darkened the stem of the elm-trees, then the insect produced is of a 

 sombre grey hue ; the curious fact may also be noticed that the off- 

 spring never resembles the parents, but always the grandparents.
