Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
Hypsĭpylē, ēs, f., = Ὑψιπύλη, daughter of Thoas, queen of Lemnos in the time of the Argonauts; she saved her father when the women killed all the men; she also entertained Jason, Stat. Th. 4, 739 sq.; Ov. H. 6, 1 sq.; Val. Fl. 2, 90 sq.; Prop. 1, 15, 18: Hypsipyles patria, i. e. Lemnos, Ov. M. 13, 399.
Hence, Hypsĭpylēus, a, um, adj.: tellus, i. e. Lemnos, Ov. F. 3, 82.
