Kovács, L.: Data to the knowledge of Hungarian Macrolepidoptera. V. The occurrence and distribution of some noctuid species (Lepidoptera) in Hungary

Map 1 : The localités up to the end of 1969, of Ogygia nigrescent; HÖFXKR (empty circles) and Lithophane semibrunnea HAWOBTH (full circles) in Hungary at Kecskeinét. Il is also further characteristic of forcipula that it is locally not rare in ruderal territories in the environment of the capital. 2. Noctua orbona HUFNAGEL, 1766, and Noctua interposita HÜBNER, 1789, in Hungary. CH. BOURSIN, the excellent specialist in the systematics of the Noctuidae has shown in a paper published in 1963 that Noctua orbona and interposita are. contrarily to earlier usage and concept, not forms of the same specie's hut distinct specific taxa, well separable also by differences in their genital organs. His findings evoke great interest and investigations began everywhere to clear up the distribution of the two species. With respect to Hungary, I made the necessary examinations already some years ago and also lectured on the results in our Entomological Society. Though this problem is an organic part of faunistical investigations conducted at an international level, I have only now occasion to make available my data also to the larger lepidopterological public. There is no doubt that both species are indigenous to Hungary, but there are essential differences in their distribution. Whereas the occurrence of interposita is wellnigh contiguous in the northern part of the country, the area of orbona is considerably disjointed. Furthermore, there is only one interposita specimen known as yet from the Great Plains (Őcsa), but of the merely half as many localities of orbona a greater number falls into that region (Tâss and Peszér between the Danube and the Tisza, and Bátorliget in the northeast of the Plains). The details of the distribution of the two species are illustrated by Map 2. In plotting the locality data, I used only reliable informations. To begin with, interposita has not yet been found west of the Mts. Bakony in the Transdanubia. In this latter region, the southern borders of its occurrence appears to be the Lakes Balaton and Velence, then the hilly region around Gödöllő in the east. Locality data are available from the northern part of the Central Range (Mts. Cserhát, Mátra, Bükk), and from the hilly area of Tokaj and the Mts. Zemplén in its eastern section. The map shows a total of 22 localities. Most of the localities derive from the environment of Budapest, the best explored part of the country. This circumstance makes it highly probable that the
