The Panarion of Epiphanius of Salamis, Books II and III. De Fide.
Second, revised edition. Translated by
Frank Williams (Leiden: Brill, 2013), p. 20:
14,4 They are called Tascodrugians for the following reason. Their word
for "peg" is "tascus," and "drungus" is their word for "nostril" or "snout."
And since they put their licking finger, as we call it, on their nostril when
they pray, for dejection, if you please, and would-be righteousness, some
people have given them the name of Tascodrugians, or "nose-pickers."75
75 Filast. Haer. 76 appears to describe this group under the name of "Passalorinchitae."
At Haer. 75 he speaks of "Ascodrugians," who dance wildly around an inflated wineskin.
καλοῦνται δὲ διὰ τοιαύτην αἰτίαν Τασκοδρουγῖται· τασκὸς παρ' αὐτοῖς πάσσαλος καλεῖται, δροῦγγος δὲ μυκτὴρ εἴτ' οὖν ῥύγχος καλεῖται, καὶ ἀπὸ τοῦ τιθέναι ἑαυτῶν τὸν δάκτυλον τὸν λεγόμενον λιχανὸν ἐπὶ τὸν μυκτῆρα ἐν τῷ εὔχεσθαι, δῆθεν κατηφείας χάριν καὶ ἐθελοδικαιοσύνης, ἐκλήθησαν ὑπό τινων Τασκοδρουγῖται τουτέστιν πασσαλορυγχῖται.
