investigation. The observations relate nearly entirely to British 
species of Lepidoptera. The author considers that the colour aud 
texture of the undersides of the food-leaves undoubtedly influence 
the colour of the larvse. In the case of Pygcera bucephalus , he says 
that variations in the colour of the derived pigments in the blood occur 
apparently spontaneously and uselessly.

being unnamed. The author believes that “ Japan has received her
