It is likely that the section describing the Arcadian descendants of Pelasgus and Arcas followed that of the Inachids. Pelasgus was autochthonous; he sired Lycaon either by the Oceanid Meliboea or by Cyllene, the oread of an Arcadian mountain which still bears her name. Lycaon's fifty impious sons drew the ire of Zeus and were all destroyed, save Nyctimus. The majority of the subsequently covered Arcadian figures descend from Arcas, who was the son of Zeus and Callisto, a local nymph. A familiar version of her catasterism is attributed to Hesiod by Pseudo-Eratosthenes, but the Hesiodic work intended in this citation might have been the Astronomia. Arcas had at least two sons: Elatus and Apheidas. Elatus sired Aepytus, the father of Tlesenor and Peirithous; Apheidas was the father of Stheneboea, the wife of Proetus, and Aleus. Aleus' daughter Auge was for some reason entrusted to the care of Teuthras in Mysia, where she lay with Heracles and bore Telephus. Telephus was on the Mysian throne when the Greek expedition to Troy accidentally landed there and found themselves fighting fellow Achaeans.
