Contributions on the order of {alpha}{sup 2}(Z{alpha}){sup 5} to hyperfine splitting (HFS) and the Lamb shift due to the insertion of the two-loop electron self-energy diagram with overlapping divergences in the electron line are considered. An explicit expression for the two-loop self-energy diagram with overlapping divergences is obtained in the Fried-Yennie gauge. Contributions to HFS and the Lamb shift due to the diagram containing this subgraph are calculated. 5 refs., 1 fig.
