Catania

 is a city on Sicily.

South towards Syracusa
Take a bus out towards the airport. Get off the bus as soon as you can after it's come off the big spaghetti junction area. Walk back up and over the junction on the lane with the traffic going away from the airport. Take the first slip road on the left for the SP70, (signpost - Siracusa/Ragusa). Follow it under the bridge until it meets with another slip road. From there you can hitch both slip roads on the white line area.

West towards Enna / Palermo
Take a bus out towards the airport. Get off the bus as soon as you can after it's come off the big spaghetti junction area. Walk back up and over the junction on the lane with the traffic going away from the airport. Keep to the right and follow signs to Palermo to meet the top of the A19. It's a bit of a walk to get to the slip road, maybe twenty or thirty minutes. Alternatively you might be better off getting a bus to Librino and walking to the slip roads from wherever it stops, but I'm afraid I don't know the bus routes.
