The Occurrence and Distribution of Some Xoctuid Species (Lepidoptera) in Hungary By L. KOVÁCS, Budapest In Ihe following, I propose to discuss the problem of indigeousness and the distribution in Hungary of some Noctuid species. The paper is, at the same time, a reply to certain questions put either in personal discussions or in correspondence. 1. The occurrence in Hungary of Ogygia nigreseens (HÖFNER, 1887). REBEL mentioned, in earlier literature, that the species occurs also in Hungary, and cited Herkulesfürdő (Baia Herculeana), now in Rumania, as locality. A female specimen, deriving from about 20 km to the south (Orsova on the Danube), is in fact preserved in the Collection of Lepidoptera, Hungarian Natural History Museum (13 July, 1909, leg. RAICHL). However, there is no record of its occurrence in the present area of Hungary in earlier literature. The first two home localities are given, however, in my faunistic list published in 1953. and no further locality data have been available until 1956, when 1 published a Supplement to the faunistic list. Indeed, only a few new localities became known to date, and the number of collected specimens is also small. Although nigreseens is indisputably a rare occurrence in the country, I have no doubt that it is indigenous in Hungary. This assumption is substantiated by the fact that the majority of the captured specimens are freshly hatched and that our exemplars display features, though less conspicuous, by which they differ from both the western and the Transylvanian specimens. The difference is so well disguised that my attention was first called to it by the photographs made of specimens of di verse origin. Fig. 1 shows 2 pairs each of Ogygia nigreseens HÖFN., and Ogyia forcipula SCHIFF. The first pair of nigreseens derives from the neighbourhood of Regensburg, the other from our Central Range. The forcipula exemplars originate also from the Central Hangt

1 and serve for comparative purposes. The first pair is a rather sharply delineated dark form, the other is paler and with a less distinct pattern. For the sake of security, slides of the genital organs had also been made some years earlier, for which 1 am indebted to my friend Dr. L. ISSEKTJTZ. I submit below the detailed data of our home nigreseens specimens available, grouped as to higher regional units (Map 1.). 1. Budapest (13 June, 1952, çf, leg. GY. ÉHIK); 2. Mts.
