According to literature data, G. ambiguata is on the wing from June to August (VORBRODT, 1914; DE LATTIN, JOST, HEUSER, 1957, etc). As PROUT (1915) and REBEL (1903) state, the highest individual density within this period is in July. On the other hand, HOFFMAN and KLOS (1914) place the main period of flight to June, and remark that the imagos may appear in warm years already at the end of May. The Szakonyfalu specimens have been collected in the middle of June (14—17 June). . Since all specimens had been already rather worn, one may imply an earlier appear­ance in J une also in Hungary. The specimens had been listed in literature under the name Gnophos dilucidaria SCHIFF. (KOVÁCS, 1958 ; TALLÓS, 1958). It was during the reexamination of the rather worn specimens and the preparation of the genital slides that their specific relegation became clear. The respective data should therefore be corrected in the above sense. Summary The above discussion might be summarized as follows: 1. The type locality of Odontognophos dumetata dumetata TR. is Dalmatia. The specimens of the TREITSCHKE collection, one lectotype and two paralectotypes, de­posited in the Zoological Department of the Hungarian Natural History Museum, agree with TREITSCHKE'S original description (1827). The basic colour of the fore wings is chocolate brown, with a dark stripe (a "shadow") on the postmedian line. 2. The Hungarian specimens—with the exception of the single exemplar from Gerla—show a high grade of similarity with TREITSCHKE'S dumetata types. The­brown wings and the presence of the dark stripe on the submedian line are charac­teristics of general validity for them. The home populations are therefore regarded as belonging to the nominate form, hence var. saturata FUCHS becomes its junior synonym. 3. The basic colour of the Lower Austrian population is not brown but sand grey with an olive hue. The dark "shadow T " is absent. The animals have a more pregnant overall pattern than the nominate form. I consider this form as a distinct geographical subspecies and name it Gnophos dumetata vindobonica ssp. n. 4. G. pullata SCHIFF, is represented in Hungary by regionally distinct populations. The specimens from the Mts. Börzsöny essentially differ from the nominate form: the discal spot is usually not discernible on the underside of the wings, the distance of the postmedian line from the base exceeds 68 per cent of the distance between the base and the termen, whereas in all other pojDulations this value is around 60%. The male genital organ also shows some dissimilarities against the nominate form. The new subspecies is introduced under the name Gnophos pullata kovácsi ssp. n. 5. Gnophos ambiguata DUP., ranging usually in higher altitudes, had been shown from Western Hungary. This occurrence is a new proof for the zoogeographical con­nection of the above area and the Eastern Alps. References: 1.
