Old Comedy (mid fifth century BCE); see generally K.J. Dover in OCD(4) s.v. Crates(1).
[1] Not otherwise known. Perhaps a mistake for the comic poet of that name. See G. Kaibel 'Epilykos (3)' in RE 6,1 cols.158-159.
[2] The titles of only six plays are given; Jungermann proposed adding Tolmai. But the Greek signs for the numerals six and seven were easily confused by a copyist.
[3] Perhaps the play by Kallias, and so wrongly attributed here. See Korte col.1624 ; The Rivals of Aristophanes p. 513.

[1] The implicit cross-reference is to kappa 2339. This second Krates -- PCG refers to him as Crates II (saec. V/IV) -- is not mentioned elsewhere.

cf. generally sigma 1264.
[1] Headword and glosses are in fact plurals (likewise in the quotation to follow), but English idiom is less amenable to this than Greek.
[2] Variant reading for stufeligmou/s at Aristophanes, Knights 537-8 (web address 1); the gloss is derived from a scholion on these lines. The Crates mentioned here is universally assumed to be the well-known comic poet of that name: kappa 2339; OCD4 Crates(1). (Kappa 2340 is not regarded as the same man but an obscure namesake: so e.g. Dunbar 228.)
[3] Fragment of a fable in hexameters, using the adjective stufelo/s from which the headword is derived. This passage is included by Crusius in an appendix to his edition of Babrius, p. 21.
