Two new genera and two new species of Cicadellinae from Yunnan Province, China are described in this paper. The type specimens are deposited in Northwest Sci Tech University of Agriculture and Forestry (NWSUAF). Miscana, gen. nov. Type species: Miscana biangula, sp. nov.\;Diagnosis: Crown produced angually anteriorly, median length less than interocular width; crown with a median transverse concavity; ocelli located on a line between anterior eye angles, lateral clypeal sutures extending onto crown and attaining ocelli; frontoclypeus flat between the muscle impressions, anteclypeus longitudinally convex. Thorax with pronotal width greater than transocular width of head, anterior margin arc produced, posterior margin angually concave, disk with sculpturing; scutellum with transverse depression rectilinear and located slightly nearer to apex than base, flat behind transverse depression; forewing with four apical cells, of which base of second is more proximal than base of third, and base of fourth more proximal than base of second. Hindleg with femoral setal formula 2∶1∶1. Pygofer side of male with macrosetae on mid part and on basal and medial ventro margin, pygofer processes absent; subgenital plate triangular, with biseriate macrosetae; aedeagus handle like basally, bent dorsad medially, with paired processes arising near end of shaft, paraphyses absent; connective Y shaped; style not exceeding apex of connective. This new genus is similar to Poochara Stl, but differs from the latter by the following characters: crown produced angually anteriorly; forewing with base of fourth apical cell more proximal than base of second; pygofer processes absent; aedeagus with paired processes arising near end of shaft; style not exceeding apex of connective.1. Miscana biangula, sp. nov. (Figs. 1～7) Length incl. tegm.: 9.1 mm. Body shape as described in the genus. Vertex with a oblique black stripe on both sides near anterior margin, crown with a longitudinal black brown stripe at median and a small black spot on posterior margin behind each ocellus, eyes black, ocelli yellow brown; face yellow brown but red at basal margin area, frontoclypeus with many irregular longitudinal and oblique black brown stripes. Pronotum yellow brown, anterior margin area yellow white scattering with irregular black spots; scutellum with a black marking bordering anterior margin near each of its basal angles, median area with two round black brown spots and a triangular black brown small macula; forewing veins red. Venter of thorax and legs yellow brown, tibia and claws black brown. Venter of abdomen yellow brown, each segment with posterior margin red or tinged with red markings. Male genitalia as in figs.3～7.\;Holotype, Jingdong(1200 m), Yunnan Province, 17 Ⅴ 1957, coll. by A.МОНЧаЛСКИИ. Aspidia, gen. nov. Type species: Aspidia falcata , sp. nov. Diagnosis: Crown produced angually anteriorly, median length less than interocular width; crown slightly convex between ocelli; ocelli located on a line between anterior eye angles, lateral clypeal sutures extending onto crown and attaining ocelli; frontoclypeus flat between the muscle impressions, anteclypeus longitudinally convex. Pronotum with width equal to transocular width of head, anterior margin arc produced, posterior margin almost straight; scutellum with transverse depression located slightly nearer to apex than base and flat behind it; forewing with apical membrane indistinct, base of fourth apical cell is more proximal than base of third. Hindleg with femoral setal formula 2∶1∶1. Pygofer side of male with macrosetae on distal half, pygofer processes apical and short; subgenital plate triangular, extending posteriorly not to pygofer apex, with multiseriate macrosetae; aedeagus with paired processes arising not only near base of shaft, but also near end of shaft, paraphyses absent; connective Y shaped; style short, exending posteriorly only to mid length of connective.\;This new genus is very similar to Sochinsogonia Young, but can b
