Both intermediates and catalysts don't show up in the overall net reaction. What distinguishes a catalyst from an intermediate is that a catalyst is there to begin with and becomes consumed (reactants side) in an elementary step only to be reformed again (products side) whereas an intermediate is formed in an elementary step (products side) only to be consumed in another elementary step (reactants side).
Catalysts are involved in the first step of the equation on the reactants side and then reformed in another elementary step as products. Intermediates are formed during an elementary step first as products and then re-used as reactants later in another elementary step. Both do not show up in the overall equation.
Intermediates can be identified when one of the products of a reaction is a reactant in a further step, meaning that the molecule was consumed. Also, the intermediates will not appear in the overall reaction.
