ANNALES HISTORICO-NATURALES MUSEI NATIONALIS HUNGARICI Tomus 57 PARS ZOOLOGICA 1965. New Oedaleus Fieb., and Bryodema Fieb. (Orthoptera) Species from Central and East Asia By H. STEINMANN, Budapest The working up of the Orthopteran Collection of the Hungarian Natural History Museum began in recent years. A rich material had accumulated especially from Central and East Asia. In the course of indentification of the more than ten thousand specimens, also 2 new taxa were found, whose description and respective insertion into the key of identification constructed for the particular faunas given above are as follows. Acrididae Oedipodinae Oedaleus FIEBER 1853 Oedaleus infernalis pendulus ssp. n. (Figs. 1—6) Head, when viewed from above, short, conspicuously as wide as long. Area between eyes medium wide, but broader than width of one eye when viewed from above. Pits of vertex distinct, well discernible, essentially longer than wide. Ribs constituting posterior margin of vertical pits decurrent between eyes, terminating at their anterior portion. Frontal rib wide, considerably wider than breadth of scape. Head strongly dilating posteriorly of eyes, slightly wider from above than breadth of pronotum measured at anterior margin. In a lateral view, head thickset, only slightly longer than wide. Eyes relatively small. Antennae articulated anteriorly and about median line of eyes. Frontal rib as high as height of scape. Lateral facial rib extending below eye deep, only slightly shorter than length of eye. Median joints of antenna long, about three times longer than wide. Pronotum, when viewed from above, about equally long and wide, anterior margin visibly sinuous, posterior margin slightly elongate and postero-median section widely rounded. Median ridge of pronotum low but well discernible, medially with a conspicuous transversal furrow. Anterior (prozonal) portion of light, X-shaped pattern on surface of pronotum narrow, about half as wide as breadth of white metazonal stripe. In a lateral view, pronotum narrow, slightly arcuate, anterior and posterior margins exclinate, median section only very slightly arched. Entire median ridge lower than vertex. Laterally decumbent section, so-called lateral lobe, of pronotum small as related to other measurements of body, antero-inferior and postero-inferior corners widely rounded. Median transversal incision of breast straight, distance between longitudinal furrows small, smaller than wide.
