Passage 9.36.2
πόλις δὲ ἐγένετο ἥ τε ἐξ ἀρχῆς οἰκισθεῖσα ἡ Ἀνδρηὶς καὶ προσέκτισεν ὁ Φλεγύας ὁμώνυμον αὑτῷ, τοὺς τὰ πολεμικὰ ἀρίστους Ἑλλήνων συλλέξας ἐς αὐτήν. καὶ ἀπέστησάν τε ἀνὰ χρόνον ἀπὸ τῶν ἄλλων Ὀρχομενίων ὑπὸ ἀνοίας καὶ τόλμης οἱ Φλεγύαι καὶ ἦγον καὶ ἔφερον τοὺς προσοίκους· τέλος δὲ καὶ ἐπὶ τὸ ἱερὸν συλήσοντες στρατεύουσι τὸ ἐν Δελφοῖς, ὅτε καὶ Φιλάμμων λογάσιν Ἀργείων ἐπʼ αὐτοὺς βοηθήσας αὐτός τε ἀπέθανεν ἐν τῇ μάχῃ καὶ οἱ τῶν Ἀργείων λογάδες.
Originally, the city that was founded was Andreis, and Phlegyas later enlarged it, giving it his own name and gathering into it the best warriors among the Greeks. Over time, however, through their arrogance and rash courage, the Phlegyans revolted against the rest of the Orchomenians and began to oppress and harass their neighbours. In the end, they even marched against Delphi itself to plunder its sanctuary. At this point, Philammon, together with a picked band of Argives, came to defend Delphi against them; both he and the chosen Argives perished in the battle.
