Help with twins/doubles?

I really don’t know what these things are called! I have a song that has these…they are two eigth notes joined with a 2 over them. Just like a triplet but shorter. So how would I do this?

Sorry if this isn’t too coherent…the second coffee hasn’t kicked in yet…

I suppose the song is a jig? The two eights should last as long as three eights would normally last.
