lively, the black network very regular, the spots of the first row on the forewing very round, small. Such specimens were caught also on the Galyatető,. Mts. Mátra. Holotype: 1 <? Vác (Naszál) 5. VII. 1926., leg. U h г у к, in the Collection of the Hungarian Natural History Museum. Paratypes : 2 £ from the same place, 4. VI. 1925., leg. Parlay, in the Collection of the Museum ; Mátra (Galyatető) 3 $ 28. VI. 1925., leg. P a r 1 а у, 4 <? 20. VI. 1927. and 1 ej 21. VI. 1927., leg. U h г у к, in the Colleótion of the Museum ; 1 $ from the same place, 18. VI. 1925., in the collection of L. Kovács. Forma szadaensis f. n. The britomartis collected on the low southern slopes of the Mts. Cserhát, around Szada, have a ground color tending to yellow.. The black elements of the pattern are also rather well developed, strikingly extended in the base of the hindwings. Holotype : 1 S Szada VI. 1909., paratypes 3 S from the same locality and date, leg. A. S с h m i d t, all in the Collection of the Hungarian Natural History Museum. Forma matrica f. п. The britomartis flying arouad Mátraháza in the Mts. Mátra, at a 600 meters altitude, have slightly elongated forewings, not so round as usual in this group. Their color is somewhat brighter. Holotype 1 c> Mátraháza VII. 1944., leg. F a b r i с i u s, in the collection of E. Fabricius; paratypes of the same locality 1 VI. 1942. and 2 ^ VII. 1944., leg. F a b r i с i u s r in the collection of E. F a b r i с i u s ; 3 S from the same place 16. VI. 1934.,. leg. Gergely, in the collection of Í.Gergely. It is worthy of mention yet that, eastwards to the Mts. Mátra, strikingly small specimens occur flying together with normally sized individuals. Their color is also pale. The brown filling in the basally proximal spots of the third, treak on the underside of the hindwings is rather strong. 2 b. The population of the Bükk plateau. We have left out of the Central Mountains' group the britomartis specimens collected on the plateau of the Mts. Bükk. This is explained, as formerly discussed, by the long and slender form of the processus posterior on the valva of the male genitalia. There appear,however, peculiarities in external characters,, too, justifying their separation. Alar expanse of males 29—33 mm, in the two females at our disposal 30 mm. Shape of forewings rather pointed in apex,, flattening slightly in tornus, with convex margin. Ground color pale, of a bright reddish brown. Color of black pattern a vivid black on forewing. Underside of wings conforms in design with former group, yet lighter and shiny. Females stand nearer to males both in color and pattern, and, in which they deviate from other females of the Central Mountains, they are just as bright. We name this special race of the Mts. Bükk M. britomartis ssp. confulgens ssp. n. Holotype : . 1 Bükk plateau (around Mt. Bálvány), 11—14. VII. 1950., leg. I s s e к u t z, in the collection of L. Issekutz; allotype 1 Ç, same place, 15—18. VU. 1952.,. leg. I s s e к u t z, in the collection of L. Issekutz; paratypes 25c? (1950) and 1 Ç (1952),. same place, of which 22$ and 1 $ in the collection of L. Issekutz, and 3Ç in the collection of L. Kovács, , We had at our disposal sufficient britomartis material from abroad from two localities only, allowing to establish their particular characters. These will be set forth below, to complete the systematical part. This is the more desirable as we have already made reference to them, though we have not met with their description in the relevant literature.
