2. Orthosia porosa E VERSMANN, with the description of a new subspecies When EVERSMANN described his cavernosa, he already had in his hands specimens of the taxon now under discussion, but he as well as others recognized only later that they were confronted in fact by two distinct though superficially similar species. Their separation was made in 1854. The exemplars serving for the description originated from the SW forefoot of the Ural range, the Government of Orenburg (6). As far as the localities are known at present, they lie in two far-removed areas. The eastern group inhabits the largely triangular territory one of whose shorter (western) sides is the line connecting Uralsk with the mouth of the Volga, the eastern one decurrent also from the Ural to the northern shores of the Issyk-Kul, while the hypotenuse touches the northern coastline of the Black Sea, the Caspian Sea, the Aral Lake and the Issyk-Kul. — The western populations inhabit the Hungarian Plains. As to origin, it is a turano-eremic species, with respect to range, it belongs to the rare Turano-Pannonian taxa, with a disjunct distribution. Distribution in Hungary (Map 1). The known Hungarian localities are in the central part of the area between the Danube and the Tisza, and beyond the Tisza from the environs of Debrecen to the southern border of the country. The first specimen in Hungary was caught by Dr. F. Kiss, on the window of his house at Nagykapros-puszta near Polgár, Com. Hajdú, 25 July, 1910. Though F. PLLLICH reported on the discovery in 1913 (17), the important datum was wellnigh forgotten, until, more than 40 years later, two other specimens became known. One of them was captured by Dr. GY. ÉHIK at Ágasegyháza, near Kecskemét, on 9 June, 1953, the other by Dr. L. GOZMÁNY, a year later, in the railway station of Ohat-puszta near Egyek, Map 1. Distribution of Hyssia gozmanyi sp. n.
