= Synagoge kappa494, Photius kappa1176. The headword is defined here as a singular noun and is found as such (in the accusative case) in Nicephorus, Refutatio 29, with a connotation appropriate to the glosses given here. However, it is possible that what we have here is a confused gloss of the plural form of κύκηθρον , which appears in Aristophanes, Peace 654 (Web address 1), and is glossed similarly in Hesychius kappa4461. Contrary to Hesychius, the connotation in Aristophanes is 'disturber' rather than 'disturbance' (contrast Phrynichus the Atticist 83.18).
For 'gloominess' cf. under kappa 1067.
