Etymology: < scientific Latin Rhyssa, genus name ( I. L. C.

Entomology.

Any of several very large ichneumon wasps of the genus Rhyssa, which are parasitoids of the larvae of wood-boring insects in conifers, esp. those of horntails (woodwasps), which they reach using a very long ovipositor; also called giant ichneumon, sabre wasp. Also: the genus itself.
