Abstract: Three new genera, seven new species of Penlatomidae from China are described in this p醦er. Poecilocoris baltcatus (Distant) (Scutellcridae), Nevisanus nagaensis Distant and Glau-cias nigromarginatus Stal (Pentatomidae) are recorded as new to China. The genus Acicazira Hsiao et Cheng 1977 is synonymized with subgenus Teratocazira Breddin 1903 of Cazira; Acica-zira gibbosa Hsiao a Cheng 1977 is synonymized with Cazira (Teratocazira) horvathi Breddin 1903. All the type specimens are deposited in Nankai University except otherwise stated. Measu-rements are in mm.Sinometis gen. nov.Type species: Sinometis emeiensis sp. nov.A member of the Hulys group, allied te Poecilometis Dallas and Eatenus Dallas of Austro-Pacific Region. Moderately large in size. Jugum not surpassing the apex of tylus. Ocelli far behind the horizontal level of hind margins of eyes. Antennae with a Poecilometis-type segmen-lation, 5-segmented, lst antennal segment short, hardly reaching the apex of head. Lateral angles of pronotum acufe. Basal medi醤 sukus of abdomen shallow and short.Sinometis emeiensis sp. nov. (figs, l, 2)Light brown or dull brownish, sometimes variegated with reddish orange or pinkish hue. lst antennal segment dorsally with a black streak, apical portions of 2nd, 3rd, St 5th segments -and most of the 4th segment of antenna black. Antero-lateral margin of pronotum broadly ma- tallic green or bronze, moderately concave medially, anterior half coarsely serrate, lateral angles rather prominently produced, acute. Both ends of connexival segments metallic green or bronze. Male genitalia as in fig. 2. Body length: (♂) 17, (♀) 18.5. Head length 3.0, width 2.9. Anten-nal segment lengths 0.9:1.75:2.3:2.9:2.4.

(kept ia the Beijing Agricultural University). Allotype ♀, locality as above, 28. VII. 1962r Wang Yi-zheng leg. Paratype l♀, Sichuan Province.Tibetocoris gen. nov.Type species: Tibetocoris spiniferus sp. nov.A member of Pentatoma complex. Size largish. Lateral margins of head slightly reflexed, parallel medially, then broadly and smoothly curving inward. Juga surpassing the apex of tylus, but not contiguous before it. Pronotum declined, antero-lateral margins sparsely armed with big spines, lateral angles square, reflexed and produced, its apical margin concave. Scutellum with basal half prominently tumid, apical portion narrow. Frenulum extending close to the apex of scutellum. Apical margin of corium sinuate, exocorium broadened medially, membrane long surpassing the apex of abdomcn. Mesosternum keeled, prosternum and metasternum normal. Scent gland auricles moderately long. Basis of venter not Swollen medially.Tihetocoris gpintferw sp. nov. (figs. 3-5)Dull ferrugineus, punctations black. Head length 2.6, width 3.3. Antennal segments I II ochraceous, III IV black, segment lengths 1.0:2.25:3.15:3.3:3. Rostrum extending to hind coxae.. Pronotum length 3.0, width 9.8, anterior angles spine-shaped, antero-lateral margins concave, with 4 large white-tipped spines, lateral angles as shown in fig. 3. Scutellum lengt h6.0, width 5.0, apex yellow, basical angle pits black, small, bordered inside by a small yellowish callose spot. Male genitalia as in figs. 4 5. Body length: (♂) 18.Holotype ♂, Xizang Autoaomous Region (Yi-gong, 2300 m., 30°15'N, 94°50'E), 30. VII. 1978. Li Fa-sheng leg. (kept in the Beijing Agricultural University).Pentatoma sordida sp. nov. (figs. 6-8)A member of ormandii group. Dull ochraceus, variegated with dense black puncturcs, which especially dense at lateral sides of head, anterior and lateral angles of pronotum. Head length 2.5, width 2.55, converging apkad. Antennae with 4th 5th segments blackish brown except the bases, segment lengths 0.7:1.4:2.0:2.2:22. Rostrum extending to 4th obdominal segment. Pronotum length 2.5, width 7.5, antero-lateral margin sharpened, broadly concave, crenulation fine and obtuse, lateral angles as in fig. 6. Scutellum d
