form), strong, thick; their inner margins with a large-sized robust tooth each, apically nearly touching. Basal plate of male genital organ typical, medially conspicuously widened, then attenuating at the line of articulation of raetaparames. Genital lobe unpaired, long at rest considerably projecting beyond median line of metaparameres (as that of all other Pseudo chelidura species). Virga short and thick, its basal vesiculum of the forficuloid type, but in contrast to that of P. orsinii and P. sinuata

, bearing also a supplementary sack (Fig. 31). Holotype male: Pic du Midi, Pyrennes, Margiut (gen.prep. No.

412, det. Dr. H. Steinmann). - Paratypen: Hab. Europe 9 (1 male, 2 females) and without labels 2 males and 1 female. - The holotype deposited in the PAN Instytut Zoologiczny, Warszawa, the paratypes bearing the labels "H^b. Europa ?" in the Zoologisches Forschungsinstituts und Museum, A. Koer'g Bonn, those vithout labels in the Természettudományi Múzeum, Budapest. Figs. 34-37. 34= Pseudochelidura sinuata (Lafresnaye, 1824), male end of abdomen with cerci, 35= male genital organ; 36= Eudohrnia metallica (Dohrn, 1864), holotype, end of abdomen with cerci, 37= male genital organ (Original) Identification key to the males of Pseudochelidura species 1 (4) Inner margin of male cerci with a large-sized tooth each, Cerci relatively short, robust, beyond their basal section not, or at most very slightly, inclinate. 2 (3) Posterior margin of last tergite with a lamelliform projection protruding between base of cerci, completely concealing low and short pygidium in the superior view (Fig. 30). Inner margins of cerci near base with a pair of extremely large-sized inclinate teeth, apically nearly touching. Median section of paramere nearly twice wider than its width measured anteriorly at articulation of parameres. An additional sack present above arcuate section of basal vesiculum at base of virga (Fig. 31) minor sp. nov. 3 (2) No lamelliform plate projecting between base of cerci on posterior margin of last tergite, pygidium short, low, triangular, well visible in the superior view (Fig. 32). Inner margins of cerci with a pair of large-sized teeth, situated not basally but in median third of cerci, though confronting each other, by far not touching apically. Virga long, its basal vesiculum forficuloid-type, strongly curved, but without a supplementary sack (Fig. 33) orsinii (Gené, 1833) 4 (1) Inner margin of male cerci with two pairs of large-sized teeth each, one pair on inner margin of cerci, confronted but with their apices slightly posteriorad, the other pair on dorsal surface of cerci, the apices opposite each other. Beyond a widened basal third, cerci sinuous inclinate in the superior view (Fig. 34). Basal vesiculum on shorter basal section of virga originating below median section of paramere, without a supplementary sac (Fig. 35) sinuata (Lafresnaye, 1824)
