From the so-called"jumping beans" of Mexico whose motions are caused by an insect within, Mr. Henry Edwards has succeeded in obtaining a beautiful moth of the Tortricidae family and probably a new species. The case is curious, as an instance of one of the lepidoptera piercing a seed capsule with its ovipositor, and laying an egg to produce a larva which will destroy the seed. This sort of performance is mostly confined to coleopterous insects. The account of this new moth was given before the San Francisco Microscopical Society.
