Descriptions of new forms Olibrus kaszabi L. MEDVEDEV, sp. n. (Fig. la, 2) Coloration of upperside dark brown or sometimes reddish brown, very shining, with faint metallic violaceous tint; antennae, labrum and other mouth parts, underside and legs reddish-yellow. Body ovate, with the maximal width in the middle, moderately narrowed anteriorly and posteriorly. Head densely and rather strongly punctured, with their interspaces without microsculpture but with sparce and extremely small punctures. Fore margin of clypeus straight. The first and the second antennái joints thick, joints 3—8 thin, the 3rd joint elongate, almost equal to the following two together, 4—5th joints elongate, 6—8th joints more short, scarcely more long of their width; antennái club elongate, its first joint triangular, practically as wide as long, the second one strongly transverse, more short and wide as compared with preceeding; the third, apical joint 3—4 times as long as the second (Fig. la). Prothorax sparsely and rather finely punctured, interspaces with more dense and extremely fine secondary punctures, without microsculpture. Elytra with fine but distinct suturai line not interrupted near scutellum and going on anterior margin; the first suturai groove deep and sharp throughout to extreme apex, the second suturai groove also deep, disappear at apical slope of elytron and in this region neared but not connected with the first groove. Other grooves very weak, scarcely visible, their intersticies finely and sparsely punctured, forming usually one not quite regular row. Apices of elytra with dense longitudinal punctures, forming here and there longitudinal rugosity. Metasternum with a few fine indistinct punctures and seems impunctured. Fig. 1.
