WARNING COLOURS AND MIMICRY. 



]}ROFESSOR Felix Plateau, in the most recently issued part 

 of the " Memoires de la Socidte" Zoologique de France," 

 gives the results of his experiments to ascertain whether the 

 Magpie moth is really, as has often been stated, an example of 

 what is termed " warning colour." This daring Professor 

 actually himself ate a number of caterpillars and found that the 

 flavour was very pleasant, reminding him of almonds. It would 

 indeed be well if all the examples of " warning colouration " 

 were subjected to as careful an examination. Equally cautious 

 also should naturalists be before accepting examples of 

 " mimicry " among animals and plants. In some cases the 

 so-called " advantageous mimicry " falls to the ground, for the 

 insect which is supposed to imitate one of its fellows appears at 

 quite a different time of year from it. — Science Gossip.
