"To Katalava Arga" (Greek script: Το κατάλαβα αργά, English translation: "I realised it too late") was the Cypriot entry in the Eurovision Song Contest 1985, performed in Greek by Lia Vissi.
The song was performed third on the night, following Finland's Sonja Lumme with "Eläköön elämä" and preceding Denmark's Hot Eyes with "Sku' du spørg' fra no'en?". At the close of voting, it had received 15 points, placing 16th in a field of 19.
The song itself is a ballad, with Vissi lamenting the fact that she realised the mistake she had done of having a relationship with a person, but she did it too late.
More remarkable, however, is the fact that this song marks the second occasion in Contest history when two sisters represented their country at different times (Lia's younger sister Anna Vissi had previously represented Cyprus at the 1982 Contest with "Mono I Agapi" as well as representing Greece in the 1980 Contest with "Autostop"). The first time that this happened was when the Finnish sisters Monica Aspelund in the 1977 Contest with Lapponia and Ami Aspelund in the 1983 Contest with Fantasiaa took part in the contest.
The song was succeeded as Cypriot representative at the 1986 Contest by Elpida with "Tora Zo".
