ON THE LIFE‐HISTORY OF “WIREWORMS” OF THE GENUS AGRIOTES ESCH.: PART IV.

Summary. The most reliable characters for distinguishing the larva of Agriotes lineatus from the closely similar larva of A. obscurus have been found in the spiracles. The spiracles of A. lineatus are longer and more parallelsided than those of A. obscurus and also bear a noticeably larger number of teeth bordering the orifices.
