I will talk about probe M5-branes in AdS5 solutions of M-theory. The dual 4d N=1 superconformal field theories arise from a large number of M5-branes wrapping a Riemann surface. The addition of a probe M5-brane can be viewed as the creation of a puncture on the Riemann surface. M2-branes ending on a probe M5-brane correspond to BPS operators in the dual SCFT. Time permitting, I will present similar results for probe M5-branes in AdS4 solutions corresponding to M5-branes wrapping a hyperbolic 3-manifold.
