Novel 2-substituted ergolinyl urea and thioruea derivatives are disclosed, as well as their use as pharmaceuticals, specifically as neuroleptics. The compounds, which possess central dopaminergic activity, have the formula ##STR1## wherein X is an oxygen or sulfur atom, R.sup.1 is a lower alkyl group, Y is a sulfur atom, S--CH.sub.2 --, C.sub.2 H.sub.4 --, --CH.dbd.CH--, or --C.tbd.C--, R.sup.2 is an aromatic ring of 5-6 atoms, 0-3 of which are O, S or N; or an aromatic ring of 5-6 atoms, 0-3 of which are O, S or N, and which is substituted by C.sub.1-2 -alkyl, C.sub.1-2 -alkoxy, nitrile, nitro, amino, C.sub.1-2 -alkylamino, carbonylamino or halo group, and C.sub.9 C.sub.10 is a CC-single or a CC-double bond and, if C.sub.9 C.sub.10 means a CC-single bond, the hydrogen atom in the 10-position is in the .alpha.-location, or a pharmaceutically acceptable acid addition salt thereof, wherein, if X is an oxygen atom, R.sup.1 is methyl and C.sub.9 C.sub.10 is a single bond, Y--R.sup.2 does not mean --C.sub.2 H.sub.4 -phenyl or --C.tbd.C--phenyl.
