Abstract. — Recently, the name llieroscopits rnfiiUis (Gmelin) has been incorrectly applied to the species long misidentified as Tlieroscopus micator (Gravenhorst). The correct name for the species in question is Theroscopus oxyphyniiis (Gravenhorst). From the original description, Carlson (1979:423) determined that the name Ichneumon micator Gravenhorst (1807) could not possibly apply to Theroscopus micator of authors and presumed that misidentifications of the species had evolved from Gravenhorsfs (1829) expanded definition of mi-cator. Sawoniewicz (1978) studied the material identified as micator in the Gravenhorst collection, selected a lectotype which apparently agrees with the original description, and transferred micator to the genus Aclastus. For Theroscopus micator of authors, Sawoniewicz used the name Theroscopus rufulus (Gmelin) and suppressed a number of names, including Hemiteles oxyphymus Gravenhorst (the holotype of which he studied), as new syn-onyms of 7. rufulus. Sawoniewiczs usage of the name rufulus is based upon a specimen in the Gravenhorst collection which Sawoniewicz implied as having been labeled by Gravenhorst as Cryptus rufulus. That specimen agrees with Graven-horsfs (1829, V. 2. p. 622) usage of Gmelin's name (cf. Gravenhorst, 1829, V. 3, pp. 1086-1087). Unfortunately, that usage of the name rufulus is in-correct. Gmelin proposed the name Ichneumon rufulus for Synistata species 311 of Zschach (1788). Zschach having published descriptions of numerous in-sects for which he provided no names. Zschachs Synistata species 366 and 312 through 316 were treated by Gmelin as varieties of rufulus and were designated by Greek letters rather than names, the usage of Greek letters for varieties being in the Linnean tradition (see Stearn, 1957:90-94). Be-cause the specimens upon which Gmelin" s varieties of rufulus are based do not qualify as syntypes of the name rufulus (see Stoll et al., 1964, p. 75,
