The headword is accusative plural, presumably extracted from the first quotation given.
[1] An approximation of part of Menander Protector fr. 18.6 Blockley (164-165), via the Excerpta de legationibus of Constantine Porphyrogenitus 158. In early 575 Tiberius Caesar (cf. tau 553 and PLRE IIIb s.v. Tiberius Constantinus(1)) sent Theodorus as envoy to Chosroes (cf. chi 418 generally) to thank the Persian king for the kind reception given to Trajan in a prior embassy. On Theodorus see PLRE IIIb s.v. Theodorus(33). On Trajan see PLRE IIIb s.v. Traianus(3). Find further extracts from this fragment at alpha 2330, alpha 2906, epsilon 1676, epsiloniota 267, and sigma 10.
[2] cf. Zenobius 1.36; see also alphaiota 386 where the Suda mss read fanerw=s ("openly") -- as translated here -- rather than the a)fane/rws ("in secret") which Adler prints.
[3] Again there is a variant reading in the quotation of this passage in alphaiota 386, which reads a)xa/ristoi ("those who lack the gifts of the graces") for this entry's *xa/rites ("the Graces"); cf. Zenobius 1.36. See also chi 124.
[4] The earliest source we have for these names of the Graces is Hesiod, Theogony 907. (See web address 1 below.) Homer mentions the Graces several times, but only once gives a name: "Pasithea" (if Iliad 14.269 is genuine).
