Scholion on Lycophron 207 notes that Callimachus and Euphorion mentioned the dismemberment of Dionysus Zagreus in their poetry.
Schol. in Lyc. 207 = Call. Aet. 643 (374)

     οἱ Τιτᾶνες τὰ Διονύσου μέλη σπαράξαντες Ἀπόλλωνι, ἀδελφῷ ὄντι αὐτοῦ, παρέθεντο ἐμβαλόντες λέβητι· ὁ δὲ παρὰ τῷ τρίποδι ἀπέθετο, ὥς φησι Καλλίμαχος καὶ Εὐφορίων λέγων
"ἂν πυρὶ Βάκχαν δίαν ὑπὲρ φιάλην ἐβάλοντο ".

     
The Titans dismembered the limbs of Dionysus and presented them to Apollo, since he was his brother, and placed them in a bronze cauldron. Apollo then placed them upon a tripod, according to Callimachus and Euphorion who say "the [dismembered body parts] should be cast upon fire-bright Bacchic saucer".

Rudolf Pfeiffer observes in a learned commentary that Orphic fragment 35 states "The Titans, who had dismembered [Dionyus], positioned a few saucers upon a tripod and cast the limbs of Dionysus into them; then Zeus assailed them with a lightning bolt and handed the limbs over to his son Apollo for burial. Apollo bore the dismembered corpse to Parnassos." Pfeiffer continues that Callimachus follows this ancient mythographic tradition. However, Pfeiffer adds that the Dionysus who is dismembered by the Titans is typically not the son of Semele but another, more ancient manifestation of Dionysus, the son of Proserpina who is called Zagreus. Callimachus treats Zagreus in Aetia frg. 43,117. That fragmentary text has been deciphered to read ὑἶα Διώνυσον Ζαγρέα γειναμένη (... she who conceived and bore a son, Dionysus Zagreus) [cf. Annette Harder, ed., Call. Haliartus 43b.34 w/ commentary].      — translation RTMacfarlane
