punctures.— L e g s rather slender, segments of first tarsi simple. —A edoeagus ovoidal. Proximal portion of internal sac with two rows of longer dark, curved spines, middle portion with two blind sack-shaped processes, the first sack set directly at beginning of the portion including two dark, curved „twin" spines, second sack situated at centre of this portion and including only one dark, curved spine, distal portion with 4 dense rows of shorter spines, near distal opening 10-12 serrate scales (Fig. 2).— L e n g t h 7.2-8.7 mm. Holotype çf : Hu. occ. ( = Hungária occidentalis) Velencei-tó, Sukoró, tópart, fűzfák töve rostálva, 1951. X. 9, legit Dr. Kaszab.— P aratype çf : Hu. occ., Velencei hegység, Pákozd, Bella-völgy, fűzfák töve rostálva, 1951. X. 9, legit Dr. Kaszab.— Types are deposited in the Hungarian Natural History Museum, Budapest. The species although similar to Xantholinus lichtneckerti sp. n., but differs from it by the presence of the "twin" spines and only a single isolated spine is on the middle portion of the internal sac. Bionomics: collecting data (shore of the lake, near water, sifted debries under willowtrees) suggest that it a stenotopic, hygrophilous, phytodetriticolous species. Distribution: Hungary, where is possibly endemic. The specific name magyaricus is derived from the word magyar, meaning Hungarian. Xantholinus (Meneidophallus) pseudobalaton sp. n. (Fig. 3) Elongate, slender, head dark brown or black, thorax dark, elytra pale pitchy-black, abdomen dark brown, antennae, mouthparts and legs reddish —rufotestaceous. Head ovoidal, longer than wide (40 : 32), from posterior margins of small and flat compound eyes to broadly rounded posterior angles slightly dilated (30 : 32). Rather shining, deeply and sparingly puncturated, surface covered with fine transversal waves except on vertex midlongitudinally and anteriomedially, where it is smooth and shining with only very fine microscopical punctures. — Antennae rather slender, longer than head, 2nd and 3rd segments equal in length, 4th to 10th transverse, gradually thickened apically, last segment obconical, pointed obtusely. — P r o n o t u m longer than broad (40 : 30), slightly narrowed behind (30 : 27) sides straight, both dorsal rows with 8-10 large punctures, lateral rows curved, fused distally with 6-8 punctures, some irregural additional punctures mostly on apical part, disc smooth and shining, covered only by very fine microscopical punctures, both marginal side with trace of very fine waves, especially near anterior angles. —E 1 y t r a a little shorter than pronotum (38 :40), slightly dilated posteriorly (28 : 32), surface shagreened among covered microscopical punctures and shallow, large scattered punctures. — A b d o m e n slender, a little widened behind of the 6th (visible) segment, then narrowed apically, surface covered by fine transversal waves, among sparingly puncturated. — L e g s rather slender, segments of the first tarsi simple. —A edoeagus ovoidal. Proximal portion of internal sac with two rows of longer dark curved spines, middle portion on centre near opposite-situated two blind sack-shaped processes; both including one strong dark curved spine, different from Xantholinus (Meneidophallus ) balaton BORDONI, 1972 in which the first posessing strong spine situated directly at beginning of this portion and only second with strong spine set on centre of this portion. Distal portion furnished with four dense rows of shorter spines at near distal opening with 12-15 serrate scales (Fig. 3).— L e n g t h : 7.1-8.8 mm. Holotype çf : Siófok (Umg.), Lichtneckert —without further indication. — P aratypeçf: Dombóvár, 1947. III. 10, árvíz, rostálva, leg. Gebhardt. —Types are deposited in the Hungarian Natural History Museum, Budapest. Bionomics: collecting data (flood debries, shifted) suggest that the species is hygrophilous and phytodetriticolous. Distribution: Hungary where it seems to be endemic. The species is very similar to Xantholinus (Meneidophallus) balaton BORDONI, 1972, but it can be separated from the latter by the build of its aedoeagus, especially the position of the large, dark curved spines on the middle portion of the internal sac. The specific name is derived from Balaton —name the largest Hungarian lake —and "pseudo".
