A graph G is called {H1, H2,...,Hk}-free if G contains no induced subgraph isomorphic to any Hi, 1 ≤ i ≤ k. Let G be a 3-connected {K1,4,,K1,4 + e}-free graphs of order n ≥ 30. If δ(G)≥(n + 5)/5, then G is hamiltonian, where K1,4+e is a graph obtained by joining a pair of nonadjacent vertices in a K1,4.
