The Distribution of the Gnophos-Group (Lepidoptera, Geometridae) in Hungary. II. By A. VOJNITS, Budapest In the first part of the present series of papers (VOJNITS, 1967), I have discussed three species (Odontognophos dumetata TH., Gnophos pullata SCHIFF., and 67. ambiguata DUP.). In the followings, I propose to examine four other Gnophos species occuring in Hungary (Gnophos furvata SCHIFF., G. obscurata SCHIFF., G. intermedia WHLI., and G. variegata Due.). Griiophos furvata SCHIFF. A Submediterranean species, distributed in Central Europe (VARGA, 1964), but besides its main range in Central and South Europe (PROUT, 1915), it was collected also in the western confines of Europe, indeed, also in Belgium (WEHRLI, 1955). In Hungary, the species was collected in most parts of the Central Range (Mts. Bakony, Mts. Velence, Mts. Dunazug, Fót, Mts. Börzsöny, Mts. Mátra, Mts. Bükk), and in Sopron on the Austrian border. G. furvata SCHIFF, does not belong to the "saxophilous" species in the strict sense (as witnessed also by its occurrence in Fót bordering on the Great Plains), though most of its localities are rocky and stony sites, or their immediate vicinity. According to WEHRLI (1955), the species is on the wing in June —August, but he also refers to DANNEHL'S observations in November. G. furvata SCHIFF, flies in Hungary in July —August, the peak of its occurrence being in the second half of July and the first half of August. TURATI (1919) regarded the race flying in Southern Italy as the nominate form. This is brownish with a darker suffusion, lighter ochraceous striguláé and dots. The median field is dark but not conspicuously so. He described the Central Italian race, of an ashy basic colour, strongly distinct dark grey median field, and blackish striguláé, as f. cinerascens. WEHRLI (1955) called attention to the fact that DENIS and SCHIFFERMÜLLER emphasized the "blackish grey" and not brownish colour in their description. Since DENIS and SCHIFFERMÜLLER based their description on a specimen originating from the environment of Vienna, and as there is the very distinct difference in the basic colour given above, it is not likely that the Southern Italian population belongs to the nominate form. For a final solution of the problem, one would need larger series deriving from the areas under discussion. According to my examinations, the Hungarian specimens belong to the nominate form. On the basis of the copious home material at my disposal, it is quite evident that the basic colour of the species rather varies, nor can the correlation between the basic colour of the wings and that of the rocky substrate (WARNECKE, 1929) — established for a number of other Gnophos-species — be demonstrated. The majority of our specimens is brownish grey, but a significant number, originating from our hilly and mountainous areas, is iron grey (Sümeg, Mts. Börzsöny, Mts. Mátra, Mts.
