Phytophagic or Biological Races in Insects
MR. MEYRICK points out in his letter (NATURE, Mar. 12, p. 388) that the idea of biological races is by no means a new one, and, judging from his last paragraph, he seems to think that the principle may be of but little importance as a factor in the production of new species. It may not be out of place to direct attention to the fact that the phenomenon appears to be very widespread among the Insecta.
