It is calculated that out of 885,000 known species of arthropods of which 815,000 are insects at least 82,500 species can synthesize poisons. The constituents of these poisons are identified in part for only 426 species, of which 342 are insects. Arthropods of particular interest in this respect are listed and the chemical compounds identified in the poison of each species indicated. The following are new compounds, identified for the first time in arthropod poisons iridomyrmecin pederin iridodial dendrolasin pseudopederin pederone cossin A cossin B cossin C cossin 1 cossin 2 cossin 3 cossin B1 cossin C1 zeuzerina dolichodial cybisterone diidrocybisterone. A chapter is devoted to each compound and a comprehensive concluding chapter and bibliography terminate the report.
