(ekhidna) of Argos
EKHIDNA ARGIA (or the Argive Echidna) was a half-woman, half-serpent Drakaina (She-Dragon) who murdered travellers passing through the lands of Argos and Arkadia. She was eventually destroyed by the hundred-eyed giant Argos Panoptes. Ekhidna's father was Peiras, son of King Argos, and her mother was Styx, the nymph of a deadly Arkadian stream.

The Argive Ekhidna was sometimes identified with Ekhidna of Arimoi, immortal wife of the giant Typhoeus. She was also related to the Argive Drakaina Poine.

Pseudo-Apollodorus, Bibliotheca 2. 4 (trans. Aldrich) (Greek mythographer C2nd A.D.) :
" Niobe the first mortal woman with hom Zeus had sex, bore Zeus a son Argos . . . He got the rule and named the Peloponnesos Argos after himself. He married Euadne, the daughter of Strymon and Neaera, and sired Ekbasos, Peiras, Epidauros, and Kriasos. The son of Ekbasos was Agenor, and his son was Argos surnamed Panoptes. This man had eyes all over his body . . . It is also said that he waited until Ekhidna fell asleep, and then killed her. She was a daughter of Tartaros and Ge, who would kidnap travellers passing by."

Pausanias, Description of Greece 8. 17. 6 (trans. Jones) (Greek travelogue C2nd A.D.) :
"Epimenides the Kretan [C5th B.C. mythographer] has also made Styx a daughter of Okeanos, but instead of mating her with Pallas he makes her the mother of Ekhidna by Peiras (End), whoever Peiras was."
